Black Bean Tree, Castanospermum australe

The seeds from this tree are a real novelty.


Not only do they come in large boat like pods, but nature has packed them in like large sardines, or perhaps rounds of cheese.

Would you believe this tree made it into the top 10 toxic plants according to interflora?

I'm talking with the plant panel:Karen Smith, editor of Hort Journal  and Jeremy Critchley, The Green Gallery wholesale nursery owner.



The reason the black bean tree made it into the top 10 toxic plants is because those large seeds weighing about 30g each, that I mentioned earlier are actually toxic.

You’re not meant to eat them, but interestingly the Black Bean seeds are also used as food in some aboriginal communities after extensive preparation to remove the toxins, of course!

Not really for your garden because the tree is quite large growing to 15 + metres.

The roots are also water seeking and this tree should not be planted near drain pipes or buildings.
