How to Grow

Cultivation

Thrives in light, moderately fertile, well drained soil in full sun or light shade; may need support if grown in richer soils (see staking perennials). Shelter from cold winds in areas prone to frosts. May die back to a woody base in cold winters

Propagation

Propagate by softwood cuttings from stems or basal shoots in early summer. Plants can be short-lived so regular propagation is recommended
