A GUIDE TO BRACHYCITON SELECTIONS

It takes a really special tree with special offerings to be called a feature tree.  Often used to break from single-species planting, to frame an entrance or as a focal point for the eye, a feature tree needs to live up to great expectations and offer amazing colour, structure, texture and/or form.

Brachychiton is a species that does just that, available from Speciality Trees. Brachychiton consists of approximately 31 species of large shrubs or trees, all except one, originating from Australia. Many of them are called pachycauls, (trees with large or swollen trunks) with the most noticeable one being the iconic Queensland Bottle Tree (Brachychiton rupestris). 

The seeds for the bigger Brachychiton develop in hard follicles creating a boat-shaped fruit which will remain on the plant for some time after the foliage has developed. These are very distinctive looking and make interesting educational specimens for playgrounds, schools and kindergartens, in fact anywhere looking to create a sensory garden.

While the Illawarra Flame Tree (Brachychiton acerifolius) has the most eye-catching red flower display of the group, flowering time may be inconsistent from one year to the next. This intermittent display together with flowering in warmer months on bare limbs is contradictory to what most people expect from a summer native.   When they are in flower, however, their beauty is breathtaking! Like Jacaranda, with its suburban purple haze effect, there is no missing this iconic tree when covered in red bell-shaped flowers.

Brachychiton can cope with a range of conditions from wetter coastal districts to the semi-arid interiors of Australia. All Brachychiton prefer to have a good wet season each year but due to their ability to store water in their trunks, can also endure substantial dry periods.

While the Illawarra Flame tree requires sizable garden space as a feature tree, the range of smaller hybrids, offer landscapers and designers more planting flexibility.

‘Bella Pink’, ‘Jerilderie Red’ (growing to 8m) and ‘Griffith Pink' (growing 5-8m) work superbly as a street tree or backyard feature tree due to their compact height and smaller footprint.  The addition of populneus in their genetics ensures a fuller form which more adequately compensates for a slightly less intense flowering regime. Known as reliable performers, each hybrid variety produces the customary bell-shaped flowers on a dense foliage structure and without the seed pods! Pleach it for a feature specimen or keep it dressed to the floor for screening - it ticks all the boxes for a small flowering native evergreen, and there are few other trees in this category!
