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[edit]
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[edit]
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.
