So, I'm growing in zone 7a, and have found that most alliums that are fall-planted do overwinter well here. Two exceptions: the I'Itois multiplier onions, and these Rakkyo multipliers. My first guess is that both these cultivars have very small bulbs which cannot withstand the winter freezes as well as the larger bulbs.
Hi all. As I many have mentioned earlier, a few months ago when I was buying rakkyo (Allium chinense) bulbs to grow in my garden, I made a truly astonishing discovery; a bulb with what was clearly a scape growing out of it. Because of this that bulb got special treatment (a pot of it's own, immediate planting, and watering on houseplant schedule. eventually the little sheath at the top opened and revealed a single "thing" which I took for a bulbil. however I left it alone, and eventually the "outside of the bulbil split revealing it was in fact a flower bud Accordign to everything I have read, Rakkyo NEVER makes flowers. Not the "nearly never" of garlic a firm "absoutely never" (then again it isn't supposed to produce bulbils either, or indeed a scape, like sofneck garlic, it's supposed to repoduce EXCLUSIVELY through bulb division.) the flower alas aborted (or more accurately the pod it produced aborted) without production of vialble seed (I probably prodded it too much). Now we get to my question, The flower is gone but I still have the plant sitting in a pot inside my house (I brought it in when I thought there might be a frost) What do you think I should do now? Specifically, should I keep the plant indoors for the winter (in the hope the warm condtions induce another flower) or take it outside like the rest of the bulbs to winterize and risk it freezing to death (because it's been inside it has something like 3x the leaf mass of the ones that got planted outside, so I'm a little worried that if I put it out now, the extra leaf growth will freeze and take the plant with them (the inside growth is a lot longer and softer than the outside ones). Can allliums even GET a second scape from the same plant, or does it have to divide and start again? Since as far as I can tell, what happened here isn't supposed to happen period, informations seems lacking and I am in the dark.
