Evening primrose is an upright biennial plant that commonly grows in meadows and disturbed sites.  This native is highly drought tolerant and attracts bees, birds and butterflies.  The pale yellow flowers open at night, close by noon and are fertilized at night by moths and bees.  It blooms during the second year of the life cycle.
