Cultivation

A species from New Zealand, ''Parsonsia variablis'' (Variable-leaved Parsonsia), was introduced into cultivation in England in 1847 as a greenhouse plant and was noted to have a sweet scent, however the flowers were regarded as "not very showy". This species is thought to be a form of ''Parsonsia heterophylla''.
