Dear gardeners, I have a suggestion to collect as much information as possible based on your personal experience growing rare species of annona. I am interested in your impressions about the taste qualities of fruits (sweetness, aroma, bad aftertaste, presence or absence of fibers), the period from planting seeds and the beginning of fruiting. What information do you have on the following species of annona: A.crassiflora, A.coriacea, A.vepretorum, A.salmaznii, A. sylvatica, A.neolaurifolia, A. stenophylla and others.
I have a couple of these species, and while I unfortunately can't offer any information on time to fruit and taste, I can share my experience with germination.
A. crassiflora I got recently; 90% of the seeds came up within 4 weeks, and they have nice, meaty stems. I expect them to be vigorous growers. A. vepretorum has a quite low germination rate in my experience, only 20%. Out of the ten seeds I tried growing, only two sprouted, and one is stunted. The one that is doing well does seem to grow fairly well though, as it's nearly a foot and a half tall after 9 months.
