Good write up on the silk tree. I am glad you mentioned the many common names. Around here, mimosa refers to the wattle acacia tree.
I appreciate the instructions on the scarification and the very thorough description of it's uses.
The whole legume family of trees is amazing.
I know of a fellow in India, who unfortunately passed away a few years ago; his name was Raju Titus. He followed the principles of Natural Farming of Masanobu Fukuoka, San. He used an acacia tree he called Subabul, and I think it was the Leucaena leucocephala. He used this tree as ground cover, and to supply nitrogen and fertility for his soil. Just like Fukuoka used white clover to grow his wheat and rice. Raju grew wheat and vegetables with the aid of this tree; he also fed his goats and sold the surplus wood they produced !!!
Raju had a beautiful farm and was totally independent and self-sufficient without any outside inputs (fertilizers etc).
So I am glad to see you looking into the silk tree for your area, and I hope it works out and grows everywhere like a weed.
For our farm, the golden rain tree, Koelreuteria paniculata, also a nitrogen fixer, wants to grow everywhere and I am delighted to see it.
