Anyone have round-leaf cassia seeds?

Hi every body,

My name’s Bach Mai Xuan and I’m a young farmer in Vietnam. I have been doing Natural Farming and Permaculture for 2 years in Thanh Hoa, VietNam. Temperature In Kerala normally ranges from 15ºC to 37ºC and rains about 1500-2000mm.

I’m looking for perennial cover crop. I have read some documents, and those said round-leaf cassia (or Wynn cassia) will be adapted with tropical climate. But I couldn't found anywhere sell it except some big company in AU.

Anyone help me?

Thank you very much!

I don't know, but I hope somebody more knowledgeable chimes in! Welcome to the forums! What is your usual weather like?
