Erigeron glaucus, Beach aster, is a small herbaceous perennial, with evergreen rounded leaves and gorgeous bee and butterfly attracting flowers. It grows 1' tall by 2' wide..great for the side of a path. I am constantly amazed by the amount of butterflies that land on these flowers! Seen so many that it is best to have a manual on California butterflies to keep up with this plant. Seriously, you can sit for 5 minutes and see 30-40 different species of insects light on the flowers.
