About

Anchusa azurea 'Dropmore' is an upright, clump-forming perennial that has a relatively short lifespan. It features alternate, smooth, and stiffly hairy leaves that are linear-elliptic to lanceolate in shape, with bases that either clasp or sit directly on the stem. From late spring through early summer, it produces vibrant blue flowers that are arranged in terminal spikes, elevating above the surrounding foliage.

About the genus

Care notes

Cultivation
Grows in any moderately fertile, moist but well-drained soil in full sun, although it can also tolerate partial shade. It thrives in moist soils but dislikes winter wet. Plants may require staking.
Pruning
Dead-head after the first flush of flowers to encourage a second flush. Cut back top-growth after flowering to encourage the development of overwintering basal rosettes.
Propagation
Propagate by seed, root cuttings in winter or by softwood cuttings from the base of young shoots in spring.
Pest resistance
Generally pest-free
Disease resistance
Can be susceptible to powdery mildews
