It’s not really about there being something better for the space. I’m fascinated with all fruits, but when I get a fixation on a particular species, I wish to grow it for its own merits, with no mind payed to more “suitable” alternatives. And besides, I’m particularly fond of berries to begin with. The more species I can grow, the better.
Am I likely to fail? Probably. But I’d rather fail firsthand than settle for thinking it will “probably” fail.
