Oenothera caespitosa

Common name tufted evening primrose
Family onagraceae
Life cycle biennial/perennial (Z4)
Flowers white to pink (late spring)
From seed germinate at room temperature
detailed seed-starting info below

The descriptions sound like a typical evening primrose, what with the flowers lasting for a day and fading from white to pink. It will be interesting to see how it differs from other similar species - the species name refers to the dense tufts of basal foliage. Some sources report this being a rampant spreader, so I'll be on the lookout for those tendencies, too. Mostly described as a wildflower, not a garden subject.

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston.
