I have cut the scapes with proliferations on them and planted in pots indoors for the winter, and magically one of them bloomed, in the pot, several times in March! I couldn't believe it. It was from a cross with a species which is probably why. This year I just decided what the heck - the prolif isn't going to make it if I leave it on the scape as it's getting cold, so for the past three weeks, every time I see one, I just break it off (none of them have roots at this point) and stick it in the ground a few inches from the parent plant. Amazingly, all of them appear to be growing. I guess it's been the right combo of coolish temps and some rain (after a very hot, dry summer). Apart from the magic indoor-blooming one, most prolifs I have planted take 2-3 years to reach blooming size. I don't normally bother with them unless they are on a plant that doesn't increase quickly, so it's worth it to get more fans through planting prolifs. Some daylilies are covered with them! I've seen scapes with four or five prolifs, all depends on the plant. Another fun aspect of daylilies.
