Southern beeblossom (Oenothera simulans) is an erect herbaceous annual that occurs naturally along roadsides and in pinelands, open woods and sandy fields. It flowers spring through summer and attracts a wide range of small pollinators, including moths and bees. The pollen grains are held together by a threadlike substance and can only be collected by pollinators that are morphologically specialized. Its flowers open at night (hence the family name, evening primrose), so only pollinators that forage at night can pollinate them. Birds have been known to eat Southern beeblossom seeds.
