Last year I ordered moringa seed online, scarified by boiling water method, let soak for 24 hrs. Planted five in various areas of yard. Morning sun one is over 9 feet tall, others range down to five ft for ones in the most shaded areas. Next year I'll have seeds for more.
Also went out to a local park and got some bean pods from mimosas found at park, used above method and planted 4 or five seeds (2 in hole) and after one season they are about five feet tall.
Also ordered aronia berry cuttings and got a couple of them going, they are ony about three feet tall.
Inexpensive and effective.....
