CultivationGrow in full sun or partial shade (although autumn colour is better if grown in full sun), in a well-drained but moisture-retentive soil
PestsFireblight may be a problem.

Flower DescriptionThe flowers are larger than in A. arborea and more numerous than seen in A. laevis, and are pure white and fragrant.
