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]

Cultivation[edit]

High quality cut stem bunches of 'Grace Salmon' and 'Grace Rose Pink' grown in a winter and spring greenhouse.

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.

A gallery of satin flower cultivars is presented below.
