I wonder. I'm a complete novice with daylily seeds, but I had huge numbers of seedlings seemingly go dormant which are now showing new growth. I actually thought they were dead, but it appears that next to none were. Their growth is corresponding to the dormant daylilies outside, but I didn't let the seedlings get exposed to cold (at least freezing cold). Seemingly, they went dormant anyway. Now, like the mature plants, they have started to grow again. Probably half, maybe a bit more, of the seedlings did this. I was looking today and many of the seedlings are corresponding to the parent(s) growth habits. Of those where both parents are known and dormant, all appeared to have died and now are growing. Where both parents are evergreen the seedlings have maintained green fans except for one or two exceptions (and some even grew
) and others where the seedlings had parents that were one of each, some seedlings stayed green and some siblings appeared to have died and are now waking up. I'm surprised I didn't toss a lot of pots with seedlings, but usually there was one visibly with a touch of green so I just kept treating all of them the same. I really thought a lot had just died but I think now very few actually did. If it's a dormancy situation, it wasn't triggered by being subjected to freezing temps. The timing of both going dormant and restarting active growth corresponds to the mature plants. I'm somewhat bemused by it all, to tell the truth. The new growth on the seedlings is broader on those coming out of dormancy, too. They look different at this stage than those that stayed green and growing. The latter still have slender leaves which all of them started with. I'm a bit puzzled. The plan was to get a head start by keeping them growing all winter, but they seemed to have taken a nap anyway.
