Southern beeblossom (Oenothera simulans)
Click on terms for botanical definitions.
Southern beeblossom is an erect herbaceous annual. It produces wandlike spikes of fuzzy, reddish-pink buds that open in the evening as delicate white four-petaled blossoms. They turn pink the following day and then wither away. Each flower has four narrow sepals, eight prominent stamens with reddish-brown anthers, and a long pistil that flares open at the tip. Stems emerge from basal rosettes of long, lanceolate leaves with toothed margins. Stems are long, slender and widely branched, giving the plant a lanky appearance. Stem leaves are sessile with entire or toothed margins and are alternately arranged.
Southern beeblossom 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.
Oenethera simulans was previously named Gaura angustifolia. The genera Gaura and Calylophus were once separate but have now been combined with Oenothera based on DNA evidence.
