Lilies (true lilies such as Asiatics etc.) can be planted just about anytime the ground can be worked. If planted too late in the season they probably will not bloom the first year but will most likely send up foliage at least.

Daylilies are not actually a bulb, they do have tuberous roots that will store extra food/water. Daylilies can usually be planted at any point up til about a month before cold weather starts to move in. If you plant them just before it gets real cold they may still make it with mulch, but they do better going into winter with a good root system. If these are in bags the one thing you want to be very careful of is rot, plastic leads to condensation and if you have a daylily plant that has sat in that type of condition for awhile then chances are there are quite a few that are really rotting. If possible I would try to open any before you buy them to see if they look or smell bad.

Excellent!! Thanks so much!!

Where I live in zone 8, daylilies can survive the winter sitting on top of the ground unplanted. I don't know about the colder zones. I have better success with lilies since I started potting the bulbs I get in fall in pots instead of in the ground, and I keep them all winter in my cold but non-freezing garage, then plant them out in spring after they have come up in the pots. I have to be careful but they do well. Lilies I planted out in fall had a poor chance of coming up in spring, I think squirrels get a lot of them.

I just bought 14pc perennial butterfly garden has day lilly liatris spicata and astilbe is it ok to plant now?

Well, you can't store them so you'll have to plant them now. But since we don't know where you're located, what state the plants are in or what your weather and soil conditions are like, nobody can tell you if you'll be successful.

Ps it's best to post a new question if you're starting a new topic. People don't necessarily look at a thread that's 13 years old.
