I just bought 2 butterfly plants ( asclepias) at walmart the other day. I had my eyes out for them last year but didn't see any. I had seen then there a few weeks ago and thought it was too early to start buying flowers. I was afraid I would not get any if I waited sooooo. They came packages like you see claimants, in a tightly closed plastic bag inside a box. Now I'm wondering how I should care for them till spring. They are a spring/early summer bloomer. There is absolute nothing about planting on the box. I thought maybe I should put them in a pot and care for them in the house till it is time to plant them outside.
