• large showy flowers • large gumnuts. • Aroma or smell can also be a significant
feature - some Grevillias smell like dirty socks!

Plant descriptions
• Plant descriptions provide useful information in recognising and identifying plants
![Page 20: describing plants - TAFE NSW...Identifiable characteristics • Identifiable characteristics are the features that describe a plant - in other words, they tell you what the plant looks](https://reader034.vdocuments.mx/reader034/viewer/2022052500/5f15eb6672bd0b12c7003b05/html5/thumbnails/20.jpg)
Now let's look at an example. Below is a description of Callistemon viminalis.
Its description is as follows:
• 'A graceful weeping bottlebrush which will grow to about 4 metres and a width of about 2 metres. Growth will vary depending on the growing conditions. The foliage is light green and the new growth is bronze. It has a greyish scaly bark. It has large red bottlebrush-like flowers.’
![Page 21: describing plants - TAFE NSW...Identifiable characteristics • Identifiable characteristics are the features that describe a plant - in other words, they tell you what the plant looks](https://reader034.vdocuments.mx/reader034/viewer/2022052500/5f15eb6672bd0b12c7003b05/html5/thumbnails/21.jpg)
![Page 22: describing plants - TAFE NSW...Identifiable characteristics • Identifiable characteristics are the features that describe a plant - in other words, they tell you what the plant looks](https://reader034.vdocuments.mx/reader034/viewer/2022052500/5f15eb6672bd0b12c7003b05/html5/thumbnails/22.jpg)
• All of the features mentioned above are examples of identifiable characteristics.
• The significant features include: • large red bottlebrush-like flowers • 'graceful weeping' appearance • The growth habit is determined by its size (4
metres) - it is either a small tree or a large shrub
