I got some new Daylily fans this fall from a NGA member. I potted them all up in pots and have them in my garage under lights and want to know if anyone has experience with leaving them in pots all winter. Some of them are pretty small fans which makes me nervous about planting them outside. Let me know if you think they would survive my winter if I planted them in the ground, either in or out of the pot. Also would they be best in my garage where it is kept at 50 degrees all winter or would they be better out in my garden shed that is not heated? Any suggestions would be appreciated. I just don't want to kill them.
Thanks,
Jeanne from Iowa

How long have they been potted, and did they come from a similar climate?

Gardenglassgems: I am not a huge grower of Daylilies although I am starting to add to my collection. I have found every time, that when I bring potted Daylilies in that I had outside for the summer and never got to plant, they winter extremey well inside a basement with light, and probably without light as well. I even forget about them, and the soil in the pots is rock hard, often. I even found one this past Spring that went unnoticed behind a step ladder all last Winter, and is now planted out and a couple blooms late Summer. I don't think one could kill them if they wanted to! Cheers!

@sooby They have only been potted up for 2-3 weeks. That's why I am afraid to plant them outside cause our nights have been getting cold and we get frost most mornings.

@FrankMosher Thanks for that information. I think I will stop watering them and leave them in a 50 degree area for the winter and then take them to the patio in the spring and start watering them. I will pray all winter that they will come back. I have several pots of each kind so I could keep them over winter a couple different ways and see what happens. Shrug!

I forgot to mention something in that they are "lilies" and as such, whether in the ground or in the basement, they need to go dormant and automatically do. While I store Dahlia bulbs in the basement in sawdust away from light, and kept dry, I also do the same thing with Oriental bulbs which I had growing on a deck. So with Daylilies, I would keep them dry, and I don't think light matters. Remember, I am not an expert on Daylilies, but I might become so if I live long enough????? Highly unlikely!!! LOL.

Frank, daylilies are not lilies, they are not even in the lily family, and they can be grown as houseplants over winter in a sunny windowsill, I've done that several times. Most have not gone dormant although one or two have. Most that had died back and gone dormant outdoors in late fall started to grow once they came into the house. I suspect that if Jeanne keeps them at 50F they too will try to grow but holding back on the water somewhat will slow them down.

Jeanne, I kept a daylily in a pot in front of a window one winter watering it only a bit once in awhile, the area it was in was kept around 55 degrees. Mine made it thru the winter and was planted the next spring. That is the only time I kept one inside over winter, so I am not an expert. I would not let them get bone dry as when they are planted in the garden even when they go dormant they still get water when it rains and snows.
If you want to be happy for a lifetime plant a garden!

I agree with Betty that you don't need to withhold water. While it's true the bulbous roots will store water they would fare better with a drink when they need one.

Also, in the spring, you'll want to re-acclimate them outdoors as you do other plants and most likely they won't skip a beat!

Best wishes! Thumbs up

Thank you so much Frank, Sue, Betty, and Sheila. Great advice. I do have a few south windows that I can put them in if I remember to give them water. Some of the others I will keep under light in the garage and will water them every so often over the winter. I really do think they will be fine. I really appreciate all your advice.

Sooby: They were. "Hemerocallis is now placed in family Asphodelaceae, subfamily Hemerocallidoideae, but used to be part of Liliaceae (which includes true lilies)."

Frank, I said they are not in the lily family but yes they were until modern methods determined that Linnaeus's placement wasn't appropriate. The genus Hemerocallis has not been placed in the Liliaceae since the 1980's. They were moved from there into their own family, Hemerocallidaceae. Some taxonomists afterwards placed them in the Xanthorrhoeaceae but not all went along with that. The Asphodelaceae placement is the most recent (APG IV - 2016). So it's a few decades since they were moved out of the lily family where they did not belong.
