Seeds Tina James’ Magic Evening Primrose

(Oenothera glazioviana) [Introduced 1987 by SESE.] The large fragrant blooms burst open suddenly at dusk. The crisp, yellow, showy four-petalled flowers circle a spire of reddish, swollen buds. Blooms are ^2/₃ open within 10 seconds or less, and fully open within 1-2 minutes! Blooming lasts 5-6 weeks or more. Will bloom indoors as a cut flower for approximately a week. Dim lights to induce flowers to open indoors in the evening. Produces a flat rosette of leaves the first year, followed by 3-4 ft. yellow spires the second year. Very hardy. During the evening the flowers are pollinated by night-flying moths as large as hummingbirds. This variety was discovered by garden writer Tina James who hosts ""primrose parties"" every year. Makes an interesting container plant for a deck or balcony and is a great conversation piece.
