Butterfly Weed Seeds

Silky Deep Red butterfly weed produces electric red and orange, umbel-type flower heads from summer until frost. It is a tropical butterfly weed which grows to 3 ft. tall and spreads to 1 ft. wide and makes a stunning, accent or background plant.

Don't confuse Silky Deep Red with the common butterfly weed, which is not nearly as showy. And yes of course, it is the King of all the plants if you happen to be a butterfly.
