Growth—

We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors in many parts of this country. The following notes are based on the general needs of the genus. Succeeds in an acid or calcareous sandy or gritty well-drained soil, disliking shady positions^[1].

Propagation

Seed - sow spring or autumn in situ. Germination usually takes place within 2 - 3 weeks at 15°c^[2]. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-20. <temperate.theferns.info/plant/Cochlearia+oblongifolia>
