South Kitsilano: I have some seeds of Asclepsia purpurascnes and I plan to plant them in a pot on our backyard deck facing south. To get the most sun, and to not spread throughout our shady garden. I don't think these will survive our winter but I can overwinter them in a shed which will not go below 10 degrees C but does not get much light. Has anyone had any experience doing this? I hope to feed monarch butterflies....
Asclepias purpurascens is a very hardy plant, no problem with overwintering in your area, even in a pot. Being deciduous, the top will die down for the winter, and will start growing again from the roots in spring.
