Growth—

Prefers a dryish well-drained sandy loam and full sun^{[1, 2]}. Heavy clay soils may induce winter rots^[2]. Succeeds in poor soils. There is some confusion over this name. ^[3] says that it is a synonym of O. grandiflora. Ait. whilst O. lamarkiana DeVries non Ser. is given as a synonym for O. glazioviana^[2]. The flowers open in the evening, they are richly scented and are very attractive to moths.

Propagation

Seed - sow in situ from late spring to early summer^[2]. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-21. <temperate.theferns.info/plant/Oenothera+lamarckiana>
