Evening Primrose Hookeri

Evening Primrose Hookeri is a perennial flower that is able to stabilize a disturbed site and will only fail if it is crowded by taller plants.  It stands at about 3 feet tall and has yellow flowers.  It can tolerate sand and seasonal flooding and it would be an excellent choice to use in a butterfly garden.  Coastal regions make a good habitat for this primrose, but it will grow elsewhere.
