That actually would be my preferred species over japanese depending on circumstance. I'm mainly partial to the secundifloras because they are native and the seeds make the necklaces for the leaders of the peyote ceremonies, look like big red beads, and quite poisonous.resistant to rats?
Beautiful looking tree. It looks like it only gets about 25ft tall though.

Interesting find. I have about 3 started now. They seem less appealing if that is the case. Please let me know if you find any more info.
we watered in a few times the first year and havent really touched it since and it seems to be doing good.
its not very big yet (9-10ft) but we have noticed that it has recently started to take off.
as i understand the one we have is not a N-fixer, but thats ok.
It's been tough for me to figure out of the Japanese Pagoda Tree is really a nitrogen fixer. The Wikipedia article on this species says that it used to be considered to be part of the Sophora genus, but, as mentioned above, it's listed as part of the Styphnolobium genus by Wikipedia ( https://en.wikipedia.org/wiki/Styphnolobium_japonicum ) which apparently doesn't fix N.
Does anyone with experience with the Japanese Pagoda tree know if this is a good candidate as a N fixer for a plant guild in an 8b (moving towards 9a...) plant guild in the Southwest (Dordogne) area of France?
