I bought 6 cuttings from various red, purple, and white flesh varieties online about a year ago. They’re all alive and some are growing great. Even in zone 8a I have to bring them in in the winter. I don’t have a green house so they spent months in the dark garage. They were semi neglected and through some mishaps 2 got snapped at the base. The bases have started growing offshoots. After leaving the broken stems laying on the concrete floor for months with no soil they still managed to double their size and grow another foot or 2 with no soil and are fine. They’re all replanted and doing well now. It’s honestly been harder to kill them then keep them alive, lol. They’re really cool plants and hopefully I can find better places to keep them.
I looked briefly into moringa trees and they’re definitely going on my plant wish list. I love plants with lots of uses and I definitely appreciate the fast growth and hardiness.
I’m reminded of the mimosa trees I see everywhere around here. You can have a decent sized bush with just a year of growth and a developed tree in 3-4.
