i have asclepias incarnata which is also called called pink butterfly-weed or swamp milkweed it likes wet places but will naturalize almost anywhere!i have it planted in my rain-garden and by the road where it is very high and dry,i just had to water it during the really dry spells the first year i planted it by the road.

I have lots of Asclepias tuberosa estabished plants ready to start blooming. The roots are long and tuberous. What are you offering to trade? You would be VERY happy with these plants, nothing small about them?
