Kurrajong is an Australian tree, Brachychiton populneus, which along with other species of the genus make interesting house plants due to their interesting leaves. Kurrajong leaves resemble poplar leaves as the epithet populneus suggests. It’s a common tree of sandy plains in Eastern Australia. The seeds are remarkably nutritious and were popular Aborigine tucker (wild gathered food). It is unlikely I will ever be able to harvest seed of this tree in the Malvaceae (mallow family), but Rowan White on the Radix Root Crops FB group reminded me that the swollen roots of young trees could also be eaten. My tree wasn’t exactly young at 9 years (seed propagated along with Brachychiton acerifolius), when I first decided to have a go in 2012, at the same time as I moved it to a bigger pot…
There were 3 young roots worth trying so I harvested them and baked them in their skins together with potatoes. They seem to need a bit longer than potatoes. The skins peeled easily off after baking and they were crispy with a good mild taste. If you have a ready supply of seed, they can be grown and harvested a bit like carrots when quite young!
This spring the tree died (at 15 years old) with no sign of life in the above ground parts, but when disposing of the plant I noticed that the young roots looked healthy, so I harvested them and repotted the remainder of the root to see if it might resprout and after several weeks in the window sill it now has fresh leaves, so not dead after all!
I didn’t get round to eat the young roots…they were left inside for a month and looked withered and inedible, but cutting in to one it looked good inside and indeed it was tasty and almost free from fibre….so we ate it in a stir-fry dish last night!
