- Description
-
Clarkia is a genus of flowering annual plants that contains 40 different species. With one exception that is native to South America (C. tenella), the plants are native to western North America. Clarkia typically grow to 2 to 3 feet high, with some species longer. The flowers resemble hollyhock and can be white, pink, or red and many species are spotted. The leaves tend to be small. These plants provide habitat for pollinators, such as the Clarkia bee that relies exclusively on the plant. The genus is named after Captain William Clark, one of the leaders of the Lewis and Clark expedition and the common name, "Farewell-to-Spring" relates to the fact that the plants bloom at the end of the wildflower season.
Seeds can be sown lightly on the surface as they need light to germinate. This plant requires excellent soil drainage, full sun or light shade, and prefers cool night temperatures and light, sandy soil with modest fertility. When planting, allow 8 to 10 inches in spacing. Allow to dry out between waterings. Its season is summer to frost, unless exposed to high temperatures.
