Clarkia speciosa ssp. immaculata

Clarkia speciosa ssp. immaculata
Pismo clarkia

Common name Pismo clarkia
Family onagraceae
Life cycle annual
Flowers magenta/white (spring)
Size 18"
Light sun
From seed germinate at room temperature
detailed seed-starting info below

Magenta flowers with a white eye, over a trailing plant with slender leaves. Some sources say it's perennial (but only to zone 7). It has certainly behaved like an annual in my zone 6 garden, where it has performed best in pots allowing it to cascade over the rims. In my experience, it seldom looks tidy, but very cheerful in bloom.

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