Named after a flower enthusiast and introduced as 'Tina James' in 1987, this large-flowered, (4") pure yellow evening primrose has a trick up its sleeve. Weedy looking during the day—it is best to site it with shorter flowers in front to hide its awkwardness— it sheds its coarse look when it bursts into bloom in the evening hours, for the flowers pop open from tightly-furled buds in under a minute. The star of many a nighttime garden party, evening primrose attracts both revelers and night-flying pollinators. Allow this biennial to shed some seeds for a yearly show, but remove most after flowering to avoid excessive self-sowing.
