Asclepias tuberosa (Butterfly Weed)

A favorite native for sunny sites. Loose masses of green foliage grow to about 2' tall and produce late summer sprays of vivid orange flowers. Attracts monarch butterflies (and lots of others) and loads of other pollinators as well. Good cut flower. Deer proof. Loves hot, sunny and dry conditions.  Those cool looking red and black bugs that cover this plant in late summer are Milkweed Bugs.  They don't really harm the plant but they will suck the juices out of the seed making them useless.  If you are trying to save the seed keep them away.
