Final Report for Trial No. 1980 – Sarracenia for a sunny windowsill 2013-2015 1

RHS Trial of Sarracenia for a Sunny Windowsill

Introduction to Sarracenia Sarracenia (common name pitcher plant) is a genus of 8 species of rhizomatous perennial carnivorous plants. They range from fully hardy to frost hardy and are found in nutrient-poor, acidic bogs from Northern Canada down to Florida in the USA. In spring, Sarracenias have cup-shaped, nodding flowers. Sarracenias can be herbaceous or evergreen and have pitchers that catch and digest insects to provide the plant with the nutrients in needs to survive and grow. Some species have some non-carnivorous leaves called phyllodes. The pitchers and their lids often have attractive markings and colouring.

Trial Location The Trial was kindly hosted by RHS Gold Medal winning Matthew Soper at his Hampshire Carnivorous Plants nursery near Southampton. www.hantsflytrap.com

Objectives The objectives of the trial were:

To identify Sarracenias which were: o Easily grown by amateurs on a sunny windowsill or similar o Attractive throughout most of the year with foliage (pitchers) of interesting

colour, patterns and form. Note: this objective was amended after the trial had started as most Sarracenias need several months’ cold or cool winter rest (e.g. in an unheated porch or conservatory) rather than being on an indoor, sunny windowsill all year round.

To clarify the nomenclature of the successful entries

To recommend the Award of Garden Merit (AGM) to entries found to be outstanding for the above purpose

Judging The Sarracenia Trials Assessment Forum members (8 of whom were members of The Carnivorous Plant Society) assessed the trial from November 2013 until November 2015; in 2013 (5th November), 2014 (25th February, 8th April, 25th June, 27th August, 18th November) and in 2015 (18th February, 7th April, 30th July, 21st September, 24th November), recommending the Award of Garden Merit to plants using the following criteria:

Colour & contrast

Venation and fenestration

Form and shape of lid, mouth and pitcher

Habit – height, proportion and stability

Vigour and quality

Number and effect of pitchers

Trial assessment 5th November 2013

Entries There were 63 entries in this trial, submitted as 3-4 year old plants by breeders, nurseries and individuals in the UK. Cultivation Entries were potted up into 10.5cm pots using growing media of 50% sphagnum based peat and 50% perlite on arrival in October 2013. This was to ensure that all plants were in the same sized pot and growing media for the trial. The plants were trialled on a raised bench in an unheated glasshouse. The glasshouse had full sun with light whitewashed shading through the summer months. The pots were stood in 5-7.5 cm (2-3”) rainwater in spring, summer and autumn. During winter they were stood on damp capillary matting and the glasshouse was not heated. Entries were cut back on 25th February and 18th November 2014 and on 18th February 2015 to remove any dead material. This was to reduce the risk of dieback from downy mildew. This exercise was done as follows:

The pitchers were carefully cut so as to only remove the dead (brown) material, whether this be the entire pitcher or just the tip of the cap

The phyllodes (non-carnivorous leaves) were not cut back if the tips were brown

As the flowering shoots had not yet grown very tall, it was agreed that they would be left in place for the time being. The trial host cut them back a couple of weeks' later when they were around 5 cm (2") tall. If they had been cut back when they were shorter than this, botrytis could have developed, worked its way down the stem and caused the crown of the plant to rot.

The largest plant of each entry was re-potted into a 1 litre container on 18th February 2015, the other 2 plants of each entry were left as they were in their original 10.5 cm pots. On 7th April 2015 any pitchers which had started to die back (or previously had their tops removed) were removed completely, leaving only fully intact pitchers on the plants. Pest and Disease During the course of the trial the systemic insecticide Admire (active ingredient imidacloprid) was used as part of the nursery’s pest control system against aphids. Plants of one entry (entry number 59, S. 'Manta Ray') had mealy bug on them when they were received which had been particularly difficult to control. These were quarantined and as the pests could not be cleared, the plants were not assessed as part of the trial. The remainder of the trial plants remained pest and disease free. Other Findings Once the top end of the flower stem had bent over so the bud was in a nodding position, the flower would take about a week to open.

Plant Name Corrected to S × moorei ‘Brooks’s Hybrid’

This plant was named after Brooks rather than Brook so there was the choice of either Brooks’ or Brooks’s. RHS botanists followed the International Code of Nomenclature for Cultivated Plants (8th ed) - Art. 35.13 where it states that for consistency we should use ‘s . For example for Bowles we use Bowles’s e.g. - Anemone hupehensis ‘Bowles’s Pink’”


Sarracenia Hybrids The following is a list of published Sarracenia hybrids detailing the crosses used to create them:

S. × ahlesii = S. alata × S. rubra S. × areolata = S. alata × S. leucophylla S. × catesbaei = S. flava × S. purpurea S. × chelsonii = S. purpurea × S. rubra S. × courtii = S. psittacina × S. purpurea S. × excellens = S. leucophylla × S. minor S. × exornata = S. alata × S. purpurea S. × formosa = S. minor × S. psittacina S. × gilpinii = S. psittacina × S. rubra S. × harperi = S. flava × S. minor S. × mitchelliana = S. leucophylla × S. purpurea S. × moorei = S. flava × S. leucophylla S. × popei = S. flava × S. rubra S. × readei = S. leucophylla × S. rubra (syn. S. × farnhamii) S. × rehderi = S. minor × S. rubra S. × slackii = S. minor × S. oreophila S. × soperi = S. alata × S. flava S. × swaniana = S. minor × S. purpurea S. × wrigleyana = S. leucophylla × S. psittacina

Hybrid which is in press and not yet published: S. × miniata = S. alata × S. minor

Other hybrids which don’t appear to be validly published but are referred to include:

S. × pureophila = S. oreophila × S. purpurea S. × psittata = S. alata × S. psittacina


Recommended Care Guide for Growing Sarracenias at Home Forum members recommended the following care and growing guide:

Spring / Summer

Keep your plant in a dish / tray of rainwater so that the water level is ¼ of the way up the pot. Top up the water level regularly as it is essential that the plant is always stood in water. If rainwater is not available then distilled, de-ionised or reverse osmosis water can be used instead. The use of tap water will kill your plant if it contains any lime.

In spring, take care not to damage the fragile emerging pitchers.

For best growth, position your plant somewhere in full sun such as a south facing windowsill or conservatory. It should be sited away from a radiator. Ventilation such as an open window would benefit the plant but is not essential.

Should your plant suffer from aphids, use your preferred method of aphid control. If spraying, it is best to do this in the evening to prevent scorch. Use of a systemic insecticide will not harm your plant.

Your plant can always be put outside for a few days over the summer if you don't think it's catching enough insects. Don't try to feed it yourself and never apply fertiliser.

Your plant can always be put outside over the summer if you wish. Autumn / Winter

Depending on the origin of the parent species, which ranges from Eastern Canada to Florida, approximately towards the end of October, some of the foliage will start to die back. Ones which originate from Florida can start to loose pitchers earlier, even in August. This is the time to give your plants its winter rest for about 2 to 3 months.

Put it somewhere bright with a temperature below 7°C (4-5°C is ideal), such as a cold greenhouse, a porch or outside. It is best to avoid prolonged frosts and not let it get below -7°C.

Cut off any dead foliage and, during the rest phase, just keep the plant damp rather stood in water – sitting it on wet capillary matting is ideal.

Depending on conditions normally towards the end of February your plant will come back into growth and can be moved back to its sunny indoor spot and stood in rainwater again.

Repotting

If the sides of the plastic pot are distorted then your Sarracenia definitely needs re-potting.

The end of February is a good time to re-pot.

A plastic pot should be always be used as a clay one may leach salts into the compost.

The recommended compost mix is 50 % sphagnum based peat and 50 % perlite (vermiculite will break down too quickly). Other growing mediums are still in the process of being trialled.
