‘reve d’Or’ and ‘Mme alfred Carriere’ are two of the most popular noisette roses available today. This class of roses originated in the United States. all other classes have origins overseas. There have been names of classes that have been made for roses that are truly american sounding such as Floribunda and Miniflora but neither of these classes of roses were originally developed in america.

The Noisette class was born in Charles Town (Charleston), SC, by John Champneys. Champneys had an incredibly interesting life. He was the son of a well-to-do loyalist who decided to remain loyal to England during the revolutionary war and was forced to flee back to london after Charles Town fell. His estate at the time was worth around 20,000 pound sterling. after the war he tried to return to Charleston but was not received with open arms. Being forced to flee back to England he was able to seek restitution for his estate of only 5,oo0 pound sterling. On his way back to Charleston for the sec-

ond time his ship had been hijacked twice and in the process he lost two family members.

When he finally made it back to Charleston he was not able to get the family estate back. He did pur-chase a piece of property just down the river, which had a well-known pleasure garden. This is where he was landscaping and hybridizing. Somewhere between 1800 and 1814 he crossed rosa moschata ‘Musk rose’ and rosa chinensis ‘Old Blush’. The re-sulting seedling was called “Champneys’ pink Clus-ter”.

So how did this new american rose get such a French sounding title? it turns out there were sever-al nurseries that Champneys could have purchased his parent roses from. as it is customary today to give friends cuttings, it was also back then. phillip Noisette, whose family in France was in the nurs-ery business, ran one of the nurseries in the area. phillip had developed a nursery close to Charleston

Editor’s Desk

Three months of the year already gone. Can you believe it? The roses are on the way. all the pruning, planting, planning done, or well on the path, for another exciting year in the garden as well as NrS. The april meeting gives us a chance to meet our Vice presi-dent, Tom Beath, and benefit from his knowledge and experience in landscap-ing as he tells us about general spring rose and garden care. You don’t want to miss it. Thanks to Gary and lycrecia Spencer for another successful Vendor Night. We had a good mix of vendors, and all seemed to be pleased with the sales. This is one of our primary sourc-es of revenue, so thanks to all vendors, as well as you, our customers.

another Nashville lawn and Garden show has come and gone. if you did not participate, you missed a great op-portunity to talk roses and NrS with a lot of interested gardeners. Thanks to all who manned the booth, and helped get the word out. We had a total of six new members join the NrS during the course of this event. Special thanks to lynda and Ken Correll for all the work scheduling the booth - a lot of work and not enough thanks. We still need volunteers for a few things. We need a host for the ice Cream Social in august for the Chile Cook off in November as well as a garden to visit for our annual picnic in June. if you would like to host any of these events, let us know. WE NEED YOU! See you at the meeting

larry Baird —

I’ll always remember the day Jim gave me my first pair of expensive rose pruners. Squeezing them in my hand provided an instant rush of self-im-portance. running around the yard, i snapped them in the air with such glee and mischief that Jim could no longer hide his all-too-familiar “What have i done?” expression. But what else was i to do? He gave them to me at a time when no pruning victims were to be found. This was likely intentional as Jim clings to a steadfast perception that i have a proclivity to get carried away

with myself. Where he got this notion, i’m sure i don’t know.

although i had still not mastered the art of pruning, i was tickled with the certainty that my new pruners affirmed my status as an expert, even if in ap-pearance only. Nothing justified my rosy existence more than these pruners … until Jim came through the door with his next gardening gifts. There is noth-ing that will swell a new rose-grower’s head faster than a fancy pair of gauntlet gloves. Throw in a holster for the prun-ers and you’ve got yourself a rose gar-dener sauntering up to the rose bushes like a gunslinger in the wild west. (Note: best not to spin the pruners like a pistol unless you’re looking for a nasty gash in your brand new red-checkered clogs.)

i recently completed my rose-gardening ensemble with a gardening belt that af-fords me a new understanding as to why men alter their stance the very instant they strap on a tool belt. When i am dressed in full rose gear, it gives me a sense of authority in the garden, if only in my head. in fact, my rose armor has inspired a new theory i plan to explore in this year’s rose garden. i am quite famil-iar with the sensitive rose-rearing tech-niques adopted by growers who nurture their roses with words of love and even classical music. While this may very well be quite an effective method, you have to remember that most of our roses are still toddlers and many of them do not have a clear understanding of who is really run-ning the show in our garden. Jim and i have taken to spoiling them in the past resulting in an unruly pack of thorny little monsters and this may be our last opportunity to show them who is slave and who is master. Simply stated, i have no intention of putting up with any rose attitude this season. No siree, none of that sensitive rose-rearing for me. This year i will garden by intimidation.

packing a pair of pruners on my right hip and a bottle of round-Up on my left, i will point one or the other at some non-suspecting bud union and dare any rose in the area to so much as drop a leaf. i will stand guard and then march back and forth in military precision with a shovel strapped over my shoulder. if they still don’t understand that i mean business, i will, directly within their

sight, peruse catalogs of easy-care ros-es making sure to openly gawk at the Knockout in the centerfold. i will leave literature lying about entitled “Bon ap-pétit for Japanese Beetles” and “Better Homes & Gardens for Spider Mites.”

Now, Jim wants nothing to do with my new regime, but by the time i’m finished with them, my roses will be begging Clint Eastwood to make their day. i know all of this may sound harsh and insensitive, but these young roses need to know their place in the hier-archy of our garden. it’s for their own good and, besides all that, their torture will hurt me worse than it will them. (right, Dad?) So that’s the plan and i am strictly adhering to it. My tough love approach will force our roses to respect my unyielding authority over them. Well, at least until one of them blooms, of course. Then, holster or no, i will likely bow down in awe and obe-dience. Gauntlets aside, i will profess my undying commitment to service any and all whims of our roses, as does any good slave to its master. Jim and i as rulers of our roses? rubbish! Why it’s as ridiculous as Jim’s unfounded belief that i sometimes get carried away with myself.

April Rose Tips Don’t let balmy weather in March

influence early winter-protec-tion removal. Freezes have been known to come in April. Keep the “frost cloth” handy for quick use. Remember this: Weather fore-casters are human. Weather con-ditions are divinely controlled.

Ted Mills, Master rosarian —

Many of us rosarians purchase new roses in April and May. Most of these roses are grown in green-houses and some tend to harbor spider mites due to their warmer environment. After getting them home, spray the undersides of the leaves on the bush with a high pressure water spray to knock off any potential critters. This can be done before the bushes are planted or after they have gone in the ground. This is a case where an ounce of prevention is worth a pound of cure.

April with Your Roses By: Larry Baird, Master Rosarian

With the winter rains and snow most of the country has experienced this year, the last thing we should need to be con-cerned with in early spring should be moisture in the soil; but don’t let that fool you, as the March winds may have had fast drying affect on your roses. So, be especially watchful that the roses do not dry out. By now, all the pruning should be done, and if you have not had a soil test to at least determine your pH, hurry to the agricultural extension office. as the soil warms, it is time to start thinking of fertilizers and additives, the food that makes possible all those May and June roses we have waited for so long. Just be aware, no matter what fertilizers you put on your beds, if the chemical composi-tion of your soil is too far off, it will not be available to your plants.

in our Tenarky district area we are fortunate to have a couple of members, who in addition to being extremely valu-able members have developed fertilizers and additives that we have used over the years with outstanding results. and while Monty’s Joy Juice and Mills Magic rose mix are excellent, ‘we all know, more is better’ so here comes the Osmo-cote, Fertilome, Bayer and all the rest. Well… maybe not. While it is so easy to look at the gigantic rose blooms that win rose shows and say, “i need more fertil-izer,” it is not all in the food. although roses are kind of like the old coon hound on the porch - if the food is there - they will eat it, maybe, this is one of the rea-sons we hear so much talk about how hard it is to grow roses. i tend to think they don’t need all the things we put there for them.

let’s just back up a little and rethink the fertilizer situation. Too much of a good thing sometimes is not good for you; e.g. as in super-sized Big Mac meals. You add too much nitrogen to the soil; you get all leaves and fewer flowers. i have discov-ered in the last few years in my garden, if my roses need more of anything, it is wa-ter. So, let’s try slowing down a little on fertilizer and be sure to supply plenty of water, water, water. There is one other reason to develop a fertilizing plan that

makes it easier on you. The older we get, the harder and harder it becomes to get down there to put on more and more ad-ditives.

if you have managed, as i usually do, to order more new roses than you have room, it is time also to prepare those new beds to accommodate them. Whether you dig deep and prepare ground level beds or build raised beds, there are a few basic principles to follow. if you are going ground level, prepare a hole at least one and one half the size of your root system, about eighteen to twenty-four inches deep. remember the formula 1/3 + 1/3 +1/3. One third the topsoil you took out of the hole mixed with one third compost and one third sand for drainage. Use the same mixture in your raised bed, how-ever this can be purchased ready made from several sources in the area. Just re-member the basic formula.

Now that the leaves are popping out, we have to talk about that dreaded dis-ease, blackspot. as in most of rose grow-ing you will hear a lot of different spray schedules. You can talk to almost any rose grower in our area, and most will say it is necessary. Some have found they have to spray every week, some say every two weeks, but most agree that in our cli-mate we have to spray a fungicide. if you are not sure what to do, ask one of the NrS consulting rosarians, and then ex-periment with your garden to determine what works best for you. as the leaves come so come the garden pests we all know, aphids, thrips, spider mites, etc. i like to refrain from spraying for these, unless i am having a severe infestation, as almost any spray that will kill these pests - will also kill the good bugs that hunt the bad bugs in our roses.

Shortly, we will be enjoying and able to share those beautiful blooms we have missed so much. remember, part of the enjoyment is in sharing with friends and neighbors. also when you share you might want to invite these friends and neighbors to join NrS and learn how to grow their own roses that will brighten the neighborhood for everyone.

and still had strong ties to his fam-ily in France. He sent cuttings to his brother who was running the fam-ily business and ‘Champneys pink Cluster’ was the rose to have at the time. it is rumored that phillip’s brother had pierre-Joseph redoute paint the rose. Sometimes there were some liberties taken with nam-ing plants and the caption for red-oute’s painting read ‘rosa Noissetti-ana’ and ‘rosier de phillip Noisette’, hence the class name Noisette.

The early noisette roses were small flowers in large clusters and climb-ing. The roses were fairly hardy and noticeably drought tolerant. There was a spurt of hybridizing the noisettes in the early to mid 19th century. The Tea roses were bred with some noisettes and this made the flowers slightly larger in smaller clusters but increased the color pal-ette that was available. Noisettes are climbers and need to be given plenty of room. They are fragrant and re-peat blooming.

‘reve d’or’ bred in 1869 by Jean-Claude Ducher’, it is a deep yellow with moderate tea fragrance and will bloom in flushes throughout the sea-son. it needs little care.

‘Mme alfred Carriere’, named after the wife of a wealthy rose fancier was bred by Joseph Schwartz in 1879, is a creamy pink with yellow highlights with a strong fragrance and average bloom size of 4 inches and will re-peat bloom throughout the season.

To see and hear more about the noisette roses and other great old garden roses that need little care, please come to the Old Garden rose Symposium on May 21st at the Wil-son County Fairgrounds brought to you by Jeff and Jennifer Harvey with the help of the Wilson County Master Gardeners.

Tenarky Winter Workshop hosted by Nashville Rose Society Declared a Success By: Mary Bates, ARS Consulting Rosarian

The highlight of the Tenarky Winter Workshop was seeing Ted and Mary alice Mills seated in the lobby of the Marriott Hotel before the opening cer-emonies and Friday night dinner. They were surrounded by rosarians from all local societies anxious to say “hello.” Ev-eryone was so pleased to see them at the event. Dan Brickman of the Tri-State rose Society had graciously agreed to drive them down to the workshop. Dressed in his dark blue “Bankers suit” with a crisp white shirt and red tie of roses, Ted looked ready to judge roses as we have seen him do so many times in the past.

as we sat listening to Ted, the conver-sation turned to the art of exhibiting; and he told us a story about an austra-lian exhibitor who visited his home and requested a tight hybrid tea bud from the garden. Working with a small sable brush and “Kleenex spit balls,” this tal-ented rosarian soon turned the rose into a potential Queen of Show. Mary alice reminisced about how all her friends were “worried about her” as she had just turned 29 during the war years and was not yet married. Soon she met a hand-some young soldier that she had known earlier and together they were tasked with the job of collecting flowers for the upcoming reunion. roses from a neigh-bor’s garden started a life-long love af-fair for each other as well as roses.

after a lovely dinner and opening remarks by Tenarky District Director Sam Jones, Troy Marden, co-host of the Nashville public Television hit show, Tennessee Gardener, presented a slide presentation of “passion for plants.”

The next morning the seminars start-ed early with Tom Seibert of Weeks roses presenting a slide show of “New and Great roses for 2011.” Tom covers the southeastern U.S. for Weeks roses. Tom told rosarians to expect a shortage of roses for 2012 as Jackson & perkins has not planted roses for the coming season. Weeks provided the roses for the auction for which the Tenarky Dis-trict is most appreciative as this is an

important fund raiser for the district.

Carolyn Shockley from arkansas was next on the agenda and gave a presenta-tion of her favorite roses including the new roses that will be available next year. Excitement grew for the new roses that would soon be auctioned as she flashed beautiful rose photos on the screen.

Gary rankin and Monica Valentovic, professors of Department of pharmacol-ogy & Toxicology at Marshall University, presented “Handy products for Grow-ing Good roses.” Their presentation in-cluded valuable information about new rose-care products they have evaluated as Co-Chairs of the arS product Evalu-ation Committee, but they also included information on various garden tools in-cluding where to find occasional good deals (Big lots) and tips on the use of the various tools. Monica even pleased those who do not like to use chemi-cal sprays with her natural formula for spraying roses for aphids and spider mites. (Mix 1 TBlS cooking oil, 1TBlS dish detergent-Dawn citrus orange or lemon, 1 TBlS Baking Soda with one gallon of water and just spray on your roses.) For more details see Mary ann Hext’s article on page 5.

pat Shanley, arS Chairman of Mar-keting and Membership, presented “Big apple roses and Bigger arS Chal-lenges.” Everyone was amazed at the dramatic photos of the rose gardens of New York City with skyscrapers in the background. pat spoke about the need to raise funds for the american rose Society during this economic downturn. also, pat announced her candidacy for arS Vice president and asked for every-one’s support.

Jeffrey Ware, Executive Director of The american rose Society, presented “Campaigning for the Grand american rose Society.” Jeff is a familiar face and everyone enjoyed having him visit with us. Jeff related how arS has made the difficult decision to reduce the office and garden staff in order to save costs. recently a change in the publishers of

the american rose resulted in a cost savings of $18,000, but there is still a need for additional funds. The cam-paign is under way to raise an addi-tional $100,000, and everyone’s help is needed. Ted Mills spoke of the need to support the american rose Society and their fund-raising efforts, as they are the heart of our local societies.

The afternoon business meeting brought discussions of the current fi-nancial dilemma that the american rose Society faces. robbie Tucker of rosemania challenged arS and the lo-cal societies “to treat our rose societies like a business.” robbie suggested rather than increase prices on membership or advertising that if the new membership drive proved to be “cost effective” and actually “retained membership,” per-haps the vendors and suppliers should be asked to help. pat Shanley, as arS Chairman of Marketing and Member-ship, accepted the challenge and sug-gested adding arS membership fliers to all outgoing rosemania shipments and stated she would continue to work hard to promote membership.

at the Saturday night dinner and auc-tion, rose sales were brisk. The most popular and in- demand roses were the fragrant ‘Crescendo,’ the rose named for the Nashville Symphony, and the new roses from Weeks and Whit Wells.

Dan Brickman presented the Out-standing Consulting rosarian award to richard Weidner, a rosarian who not only has served multiple terms as Cookeville president and Vice president but also drives to Knoxville each month to Co-Chair the Beginners Workshop for the Tennessee rose Society. Con-gratulations, richard!!!

Tennessee rose Society president, Kathy Brennan, extended an invitation to attend the Tenarky District Conven-tion and rose Show that will be held at the University of Tennessee agriculture Campus this fall. a welcome recep-

One of the most informative and enter-taining programs at the recent Tenarky Winter Workshop were Drs. Gary rankin and Monica Valentovic, profes-sors at Marshall University in Hunting-ton, WVa, and very active members of the Huntington rose Society. They are also members of the american rose So-ciety’s product Evaluation Committee which evaluates new rose care products to see if they are worthy of an arS rec-ommendation. Some of the products and tips they shared are as follows:

● An adjustable rake to easily get be-tween rose bushes. available at Big lots for only $3.99 (most had bought more expensive ones).

● Cheap single by-pass pruners for rose show prep—buy ones with colored han-dled as they are easier to find.

● Knife sharpener for pruners. Gary’s was from ace Hardware for $5.

● Use a Scotch Brite pad to remove the gunk on your pruners.

● Buy a cheap ($1) spray bottle and put in it a mixture of lysol concentrate (1 cap to 1 cup of water) to spray pruners as you work so you won’t spread disease from rose to rose. This mixture will not rust the pruners.

● Purchase a carpenter’s back brace from any hardware or home store to support your back while working the roses. it also has places to carry items, (Gary is modeling his in the photo).

Handy Products for Growing Roses from Tenarky Winter Workshop By: Mary Ann Hext

● Gloves - Purchase goatskin gloves from rosemania or The rose Gardener to keep from having cuts and scratches while working in roses. Mud gloves are great for wearing when spraying as are Cool gloves (have a rubber coating) and Bionic gloves with tip pads help with hand problems. Neoprene or Nitril dis-posable gloves are also good for mixing and spraying as they don’t absorb the chemicals.

● A headlight, available at sporting goods stores, is great for going to your rose garden at 3 a.m. before a rose show in search of the “queen.”

● Bone meal, green sand, and worm castings are recommended to put in the hole before planting a new rose.

● Monty’s Joy Juice (yellow formu-la first, then 2 weeks prior to a show change to orange formula).

● Other products to promote growth and blooms are Super Thrive and re-sponse.

● Use a cup full of Shultz Starter in a bucket of water when soaking bare root roses before planting.

● Liquid Fence is great for repelling deer if sprayed every two weeks. They also carry rabbit repellent.

● FreezeProof (also sold by Liquid Fence) is recommended for spraying roses in april when frost is predicted. Must spray six hours before the frost and cover the leaves (both sides) and canes. it has glycerin in it and is expen-sive but will last 4 weeks. During the test trial there was a problem with the

sprayer on the bottle, but that has since been corrected.

● Mills Magic Rose Mix and Mills Easy Feed were recommended as good organic fertilizers.

● Bayer All-in-One is recommend-ed for rose growers with 10-15 roses. Granular can be used once per month and is a fungicide and insecticide. it is earth-worm safe. Bayer rose and Flower for insects is also food safe and kills Japanese beetles, aphids, thrips, and mites.

● Immunox Plus is expensive but good for spot treatment for insects and diseases in small gardens. Keep sprayer 18” from flowers.

● A book called “Good Bug, Bad Bug” is very helpful in identifying insects.

● Jaz Rose Spray is useful in humid climates. it reduces heat stress and lessens the amount of watering. it is also good for potted roses.

● Monica’s recipe for organic growers for spraying roses is:

• 1 Tbs. of cooking oil (olive oil or canola oil)

• 1 Tbs. dish detergent (Dawn lemon or orange—no ammonia)

• 1 Tbs. plain baking soda

• 1 Gallon water

Shake continuously to keep the oil and water mixed. This works both as a fun-gicide and as an insecticide for aphids and spider mites. it changes the pH, and the oil prevents the fungus from getting into the leaves and smothers the mites.

Check the arS website for other recom-mended products.

Rose Rosette Disease By: Dr. Raymond A. Cloyd

rose rosette disease is a well-known infection of roses, including cultivat-ed, native, and introduced wild rose species. The disease was first discov-ered in North america (e.g., Manitoba, Canada; Wyoming; California; and Nebraska) in 1941 and is now prevalent throughout most of the Midwest. roses appear to be the only plant type suscep-tible to this disease. although multiflora rose (rosa multiflora) is extremely sus-ceptible to rose rosette, different rose types may also be infected including climbers, hybrid teas, floribundas, min-iatures, and antique or “old-fashioned” roses. The causal agent associated with rose rosette was initially considered a virus-like organism or double-stranded ribonucleic acid (rNa); however, it has now been determined to be an aster yellows phytoplasma (an organism present in phloem tissue that cannot be grown on artificial media) in the apple proliferation group (16Sr1-B).

Symptoms

rose rosette disease may cause the following symptoms:

• Rapid stem elongation • Leaf distortion • Leaf chlorosis with yellow mosaic patterns • Leaf reddening • Abnormal narrow leaflets or smaller leaves than normal • Thickened stems • Premature development of lateral buds • Excessive production of thorns

Multiple stems may also be produced at the ends of branches resulting in a ‘witches’-broom appearance. in addi-tion, lateral growth may be larger than the parent rose canes. Flower buds may abort and opened flowers may be deformed with fewer normal petals. Expression of symptoms varies depend-ing on the rose type or cultivar, plant age, and/or stage of growth (e.g., phe-nology). roses exhibiting symptoms of rose rosette may resemble plants that have been exposed to herbicides such as

glyphosate (roundup) or 2, 4-D, or have a nutritional deficiency. Multiflora roses infected with rose rosette are extremely sensitive to damage by a late frost com-pared to non-infected plants, thus con-tributing to severe dieback. in addition, infected roses may be more susceptible to fungal diseases such as powdery mil-dew. infected plants, depending on size, may die in 2 to 5 years. Symptoms of rose rosette, in general, are less severe on garden roses.

Causal Agent

rose rosette is vectored or transmit-ted by the eriophyid mite, phyllocoptes fructiphilus, which is native to North america. phyllocoptes fructiphilus is robust, spindle-shaped, and yellow to brown in color, 140 to 170 microns in length, and approximately 50 microns in width. The mite has four legs, which differs from other mite species that typically have eight legs. Mites may be observed with the use of 10X hand-lens or high-powered (200X) microscope. The mites are typically located in the angles between leaf petioles and axil-lary buds. adult mites overwinter on rose canes between partly opened buds and the angles between rose stems and petioles.

phyllocoptes fructiphilus needs living, green tissue in order to survive. in early spring, the mites migrate onto develop-ing shoots where females lay eggs. Fe-males may live up to 30 days; laying one egg per day. Young mites develop with-in the leaf folds of new shoots or under leaf petioles. The mites may move from plant-to-plant via attaching to insects. They may also be dispersed via air cur-rents (wind) from infested rose plants. Mites may start a new infection, by feed-ing on the succulent, rapidly growing tissues, after landing on an un-infected garden plant or multiflora rose. phyllo-coptes fructiphilus most often transmit rose rosette disease to plants from May through July. as such, most symptoms of infection appear in July and august. Mite populations are most abundant from June through July with the peak

occurring in September.

Symptoms on multiflora rose may ap-pear up to 90 days or more after mites have inoculated plants. adverse condi-tions such as drought and/or stress may influence transmission of the rose ro-sette disease to plants. The disease may be spread by infected pruners, so always thoroughly clean pruners with a disin-fectant (e.g., lysol) between pruning each rose plant. rose rosette may also be spread or transmitted by grafting. in fact, graft transmission tests have shown that the disease may be present or reside in the roots of multiflora ros-es. any remaining roots may produce infected shoots in 18 months or later, which can serve as a source of inoculum for non-infected roses.

Management

There is no cure for rose plants that exhibit symptoms of rose rosette dis-ease. infected or symptomatic plants must be dug-up, including the roots, and disposed of immediately. if possi-ble, eliminate all multiflora rose plants from the vicinity. There are several insecticides/miticides that may be ef-fective against p. fructiphilus including abamectin (avid), bifenthrin (Talstar), carbaryl (Sevin), endosulfan (Thiodan), and/or petroleum-based horticultural oils, if coverage is complete and applica-tions are performed frequently enough (every two weeks from april through September). However, efficacy may vary depending on the extent of the mite infestation. Furthermore, it is not really practical to try to suppress populations of the mite with insecticides/miticides. The most prudent solution in dealing with rose rosette disease is to complete-ly destroy infected rose plants.

Tenarky Winter Workshop

(Cont’d from page4)

tion will be held in the new Beall Family, rose Garden. This fun event will be held in Knoxville on September 23rd, 24th and 25th.

an arS Consulting rosarian School was held on Sunday morning with opening re-marks by Jeff Ware who made a profound statement to the crowded room of rosar-ians: “You are the american rose Society. You are the face that the public sees and depends upon for rose care.” The Consult-ing rosarian School led by Dan Brickman is Tenarky’s best-kept secret on how to grow good roses, but lots of new rosar-ians must be discovering the school as the room was packed. Expert rosarians Noah Wilson, Mike Thompson, Monica Valen-tovic, Gary rankin and Dan Brickman shared with the group their methods for growing roses.

The Tenarky District now has three new arS Consulting rosarians and a lot of folks who now know even more about growing great roses. Congratulations to Susie Ep-person, Carol Graff and Denise Thorne!

a special thank you to our District Direc-tor, Sam Jones and our First lady, Nancy, for their expert direction of the Workshop. if you missed this exciting Tenarky Dis-trict Convention and Workshop, there will be another one held this fall in Knoxville on September 23rd, 24th and 25th on the University of Tennessee agriculture Cam-pus. We are looking forward to seeing ev-eryone there. For more information, visit www.tennesseerosesociety.org.
