I had three this year. The first was on Aldersgate and then two from Green Arrow. Aldersgate was the first thing to bloom so the prolif is older than the other two by nearly a month. I left it on the scape until the top of the scape had died completely down to the prolif, but I got worried I'd forget it was there. I didn't really want water roots, but I wanted to see what was going on with it, so I fixed up a plastic water bottle and filled it with dirty creek sand and left enough of the lower scape to stabilize it in the sand at the right level and then filled it water. Seems to have worked. The Green Arrow scapes made pods, so the prolifs there had a lot longer time on the scape and got bigger and showed more incipient air roots. I can see Roots through the sides of the plastic and growing in the bottom on all of them. A photo of the three in dirty sand. They've been in a south window inside since I removed them from the scape. The smallest is Aldersgate in front:


Here's the Aldersgate prolif after being dumped out ready for planting in a pot, it didn't have even much sign of air roots when it got put in the sand:


Here it is in a 6-7" standard clay pot. This wasn't what I'd originally planned for it, but it may be how it lives through the winter:


The two Green Arrow prolifs have to wait for another day. They are larger and the roots showed up faster than on the Aldersgate prolif, but they haven't been in the sand nearly as long. Back in the window for them!

Looks like you have a good idea for rooting prolif's Donald, I have been putting them in water but I may start adding the sand.

I get lots of prolifs but have never started them in water.
I dip them in a rooting activator, stick them in a pot of peat/perlite mix,
and put them a shady spot for awhile. They root like crazy.

Sand rooting is also a good way to root plants.

This is the first year I have tried prolifs, not knowing what exactly to do with them I just stuck most of them in the ground like regular daylilies. I had one huge one with a few small ones together on one plant. The tag was dug up and misplaced by critters, I placed that one in a pot. Showed some seedlings for size comparison.

I had a prolif this year that was so energetic, it had produced 2 additional little fans on itself.

I usually just stick them in soil in pots. It works well for some cultivars but others do kark it. Unfortunately, it is usually the ones I have lots of that survive. This year I will try the water and sand!

I like that sand and water idea, too! Sounds like a successful way to get prolifs to root! Thanks for the idea, Donald!

I've had crazy luck with proliferations, free fun. I've utilized all sorts of methods of growing them with varied results. I guess I get most excited when a hybrid I'm not expecting any from produces. They tend to end up being gifted out once (somewhat) established just like loose roots or fans from division. I tend to be a little rude to them (unless they're the aforementioned "special" or have come from a particularly small division that could use a little help in bulking up).

I stuffed 7 or 8 in a large pot a few weeks back and my mom was quick to inform me they were dying. "Nope, they'll be fine" was my reply. And they are indeed, just fine. They'll be in the ground soon and survivors will end up being gifted as known, named varieties. A friend's wife called late in July thrilled with a good bloom that was 4 years in the making. Worth far more than the little bit of effort I put into it. You can't buy that with a $500 bill.

At the very least they're fun to play with.

All great ideas.

My H. lilioasphodelus have lots a blossoms and scapes, each one with a pup (proliferation). I am going to try sand and water on them. None took last year when just placed in soil.
