General Information

Plant Care Instructions By Steve Brigham

In the mild Southern California coastal climates, many kinds of milkweeds may be grown in the garden. Two of the best are Asclepias curassavica and Asclepias physocarpa, both of which are evergreen and nearly everblooming in frost-free areas. However, many cold-hardy species such as Asclepias tuberosa may perform poorly due to lack of winter cold and summer heat.

Is Indoor Plant?
