Clarkia amoena (Lehm.) A.Nels. & J.F.Macbr |
Clarkia amoena (farewell to spring, godetia, or satin flower; syn. Godetia amoena) is a flowering plant native to western North America, found in coastal hills and mountains from British Columbia south to the San Francisco Bay Area of California.
Description
It is an annual plant growing to 1 m tall, with slender, linear leaves 2–7 cm long and 2–6 mm broad. The flowers are pink to pale purple, with four broad petals 1.5–6 cm long. The fruit is a dry capsule, which splits open when mature to release the numerous seeds.
Taxonomy
Five subspecies are currently recognised, although intermediate forms are commonly found:[1]
- Clarkia amoena subsp. amoena (Lehm.) A. Nelson & J. F. Macbr. – (farewell to spring)[2]
- Clarkia amoena subsp. caurina (Abrams) C.L. Hitchc. – (northwestern farewell to spring)[3]
- Clarkia amoena subsp. huntiana (Jeps.) F.H. Lewis & M.E. Lewis – (Hunt's clarkia)[4]
- Clarkia amoena subsp. lindleyi (Dougl.) C.L. Hitchc. – (Lindley's clarkia)[5]
- Clarkia amoena subsp. whitneyi (A. Gray) H. Lewis & M. Lewis. – (Whitney's farewell to spring)[6]

Farewell to spring is commonly cultivated as a garden plant, and cultivated varieties are known.
It a cool season plant and will tolerate temperatures below 0 °C (32 °F) in gardens or greenhouses. It is a facultative long day plant, i.e., it flowers faster under long day conditions but long days are not necessary for flowering.[7] The plants grow best with minimal fertilizer rates compared to most other cut flower and flowering potted plant species. Sakata Seed Co. developed cut flower (tall; 'Grace') and flowering potted plant (short; 'Satin') cultivars introduced in the 1980s that offer great performance and uniformity.
