The seeds are edible when cooked properly.

This plant is also called the Lucky Bean Plant. The pinnate leaves are also considered poisonous to animals. Do not plant this tree next to a swimming pool, patio area or near any power lines as the root zone is very extensive. The roots can also break apart any irrigation(sprinkler lines) in your lawn. It is best to grow this plant in a small container about 8
inches in diameter. Remember to keep plant(s)away from your pets.

I have personally not tried to grow the black bean tree, but at some point in time, they were widely planted around public parks, libraries, and the like, and many stands of healthy, mature trees can be seen in the Miami, Florida area. I have not noticed that there have been any recent new plantings, however.

The generous seeds (three to a pod is typical) carry poison unless processed. Traditionally, tribal folk around Brisbane used to 'wash' away the poisons before cooking and bashing pulp into a 'damper' mix, for bread or cookies. (See J. Hauser, Brisbane) to learn fascinating detail about this truly valuable and historic tree. "Castanospermine" would yield fruit too for further research. That knowledge derives from traditional wisdoms tried and tested over many centuries (or more) around Moreton Bay, and so those values might be attached to the ongoing connection to that knowledge and land of the relevant primary custodians, where it is native at least.

This is a relatively attractive tree with very nice orange blossoms that grow in small clusters off the middle of the larger stems (not near where the leaves are). Unfortunately the blossoms are hard to see until you get underneath the tree. Makes great shade. Only for relatively warm areas of the US (can't handle a lot of frost). Seeds germinate easily, and seedlings like lots of water. As the name suggests, it's a native of Australia, though it can also be found on New Caledonia
