I have no experience with these. In fact, I didn't know what they were, but your question intrigued me. I found this link from the Floral Design Institute, which includes their flower library with conditioning and design tips. Here is a link that might be useful: Floral Design Institute Flower Library

I bought these too this year - mine say to plant after the frost Jan-May. And I did read you had to pull them up in the fall.

Hello, How are these in your garden? Did you have to dig them up and store them for the winter? I had dahlias that stayed in the ground this past winter (which I thought was pretty cold) and they came back fine. Did you plant these in the spring or fall? Thanks in advance for your info/experience. Anita

Kendra, where are you? What zone? Anyway, if the bulbs look OK, and you can dig the soil, I would just go ahead and plant them and see what happens. Jackie
