Bay, we treat this Malabar chestnut as an indoor plant, as it can purify the air quite well. Here is the mother plant. In February, there was almost nothing to do in the garden, I cut some indoor plants and see if I can multiply them from cuttings. And the answer is yes, all five plants are rooted (some need 8-10 weeks, and some need up to 12 weeks.).I looked it up, the nuts are edible and the leaves are too. Native to south and Central America, it sounds like a tropical plant. Will you have to keep it in your greenhouse? Where did you get the cuttings?
