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. 
Direct sow on cool soil in late fall after a hard frost to early spring. Needs light to germinate.  If sowing indoors, seed will need stratification. Water from bottom as needed.
