Brachychiton (Kurrajong) species
This is one of the Kurrajongs. I am not sure of the name as some seem to be lumped under the title Brachychiton diversifolius. This is the lovely sight at the entrance to a country town near here. The rainfall is a little more and is more reliable. I guess the pH of the soil is less there also which would make a big difference to the growth rate and ultimate size.
This is a tree of lower rainfall areas and quite harsh summer conditions, appearing in western New South Wales.
The flowers are like small bells in this delightful bright pink colour, followed by black boat shaped seed pods. Last week there was a carpet of spent flowers under the canopy of the tree.



I am intrigued by these pictures and the fact that the trees shown are described as Kurrajongs.
I grew up around Mulwala in Southern NSW and the trees we knew there as Kurrajongs are quite different, and botanically Brachychiton populneis.
Which I guess is why nurserymen etc have to use the botanical names as common names are often colloquially different.
I am interested in the cold hardness of Brachychiton in general and in particular the species diversifolius. I am growing it outside in Austin, Texas and it seems to have tolerated 28 degrees F. this winter. Thank you
Brachychiton diversifolius (populneus) and B rupestris (Bottle Tree) are both frost hardy to -7C (19.4F). The others are not listed as being frost hardy.
I am thinking of this tree on a suburban block… looks a bit big though… it is replacing a Liquidambar. Does anyone know if the roots of this tree go far (wide, not deep)?
We have a B. populneus ssp. populneus (the one with the poplar-like leaves) grwing in our garden that must be dozens of years old and 8 to 10 metres high.
Does anyone know whether these guys are suitable for creating and alley ?
