The people I’ve talked to have all said that it fruits very sporadically and has few fruits. Don’t know how many plants they have though. I wonder if it’s just not getting pollinated enough, and if hand pollination would help with fruit set. Perhaps the natural pollinators are a bit shy of the plant.
Will definitely keep at least a couple, and will see if cross pollination is necessary/helpful (of course, if I can keep them alive until they get old enough to fruit).
