Erigeron glaucus

Erigeron glaucus is a very flowerful & easy plant to grow in dry sun.  It blooms continuously through the summer, with the largest number of flowers coming in June.  Bloom can start in April & end in October.  Bees love it.  The normal flower color is blue-lavender.  'Sea Breeze' has pink flowers & seems to be the form most commonly sold in Seattle.  The plant is low & spreading, not more than one foot high & up to 3 feet wide.  It looks nice cascading over rocks & walls.  It is drought tolerant, but can't do entirely without water during the summer.  Water regularly, but not heavily, or more than once a week.  The stems of this plant & sometimes also the leaves survive the winter.  Don't cut it back to the base, just remove the obviously dead parts, mostly the flower heads.  It is native to the California & Oregon coasts, where it grows on bluffs, sand dunes & beaches.
