The blue porterweed is a favorite plant in the garden for the butterflies. It is an excellent plant to add to a butterfly garden as the nectar is sought out by a variety of butterfly species.

This plant has tripled in size and makes a great ground cover, and does really well in full sun. It flowers year round and has coarsely toothed leaves. The stems with the flowers grow pretty long, which gives the garden a great layered look with bursts of green and blue.
