Thanks, Becky. I actually did put the healthy ones into the ground today and I will hope for the best. Like you said, even if I don't get flowers this year I should get greenery and flowers next year.

Lilies are fine to plant now, they'll bloom this year. By windflower, do you mean those from South Africa? They aren't hardy here, so fine for spring planting. Unless it is mushy or molded (can't wipe off) get it in the ground. Even if it won't bloom this year, it has a better chance for next year in the ground than in your garage.

Plant them or throw them away. They may not bloom.

Yes, definitely plant the lily bulbs ASAP. Lilies can handle some chilly weather, so they'll be fine, and a frost won't harm the bulb at all since it is planted too far down. Plus, lilies don't really go dormant, so they don't do well at all out of the soil(and they'll probably be starting to sprout by now too, which isn't good) As for the other lilies, I would be planting them outside if I was you, just cover them if we get a late frost. Make sure you cut the blooms off when they are done flowering, for their first year especially they shut put their foliage energy into roots rather than seeds. They should probably be hardened off, put them outside in a partially shady area for a couple days, then start moving them into the sun for a couple more days and they should be good to go. If they are in little pots just be sure they don't dry out too much in the sun. To be honest, any time I've bought lilies from a greenhouse or started them indoors I haven't bothered hardening them off, I just plant them, keep them well watered for the first little bit and they've been fine. Probably not the best gardening practice, but I've always gotten away with it(with lilies, anyway)
