Been hearing from friends...here's the good news "Indian Shallot" is a TRULY perennial multiplier, tops die back in summer, lift bulbs and store else they will rot.(I feel 99% sure it is a "Potato Onion", which is a shallot cultivar). Allium canadense truly perennial for me and others for years now IF grown in DAMP soil, tops die back in May, no need to lift the bulbs. "Chinese Chives" (allium tuberosum) super reliable, almost invasive but some folks not wild about the taste. I can deal with small amounts, tends to remind me of Society Garlic, which is not an Allium My strain of Allium fistulosum is proving reliably perennial for me and others, grows year round, great seed setter. Jury still out on a few strains of Potato Onions we are trialing but looks hopeful. Tops die back in early summer, lift bulbs else they rot. Chris moved to Live Oak, is trying some there in that colder climate. "Eliska's Bunching Onion" a good multiplier, truly perennial, good seed setter......VERY close to my A. fistulosum, possibly the same. Been growing a Mystery Onion from Jon and Debbie Butts a few months now....definitely multiplying all summer, Jon says about 1 of every 12 makes a viviparous reproductive stalk much like that of Allium canadense. Now the bad news: After growing EXTREMELY vigorously at H.E.A.R.T. in Lake Wales for just under a year, the base species of Perennial Sweet Leek (Allium amperalosum sp?) that Josh Jamison grew in large numbers, have now all apparently died and vanished. I checked mine yesterday.....still alive but has actually gotten smaller. BUMMER as the flavor was excellent and the clumps were huge and grew FAST from seed and division. He gets MUCH colder there than I do in south Tampa, is in a bowl, gets teens now and then, but even that extra chilling did not seem to help it be perennial. See pics.
