Hooker's Evening Primrose
Oenothera elata
  
About Hooker's Evening Primrose (Oenothera elata) 18 Nurseries Carry This Plant Oenothera elata is a plant of the Onagraceae (Primrose) family known by the common name Evening Primrose or Hooker's Evening Primrose. It is a relatively common and widespread plant of wetlands and seasonally wet areas as well as disturbed areas. It is typically not found in standing water but nearby. There are two recognized subspecies, ssp. hookeri and ssp. hirsutissima. It is native to much of western and central North America. Ssp. hookeri was formerly considered a separate species, and some sources may still refer to it that way. It blooms copiously through the summer, the shade of its flowers varies from yellow to orange. Like other "evening" primroses, the flowers close up during mid-day. It is a prolific seeder, and gardeners will need to be prepared to pull up numerous seedlings from areas where it is not wanted. Although it is typically found in moist areas, it is also surprisingly drought tolerant. It develops a stout taproot and woody stems with age. It is a tough plant that is easy to grow.
