Masses of white daisy-like flowers with brownish yellow centres are produced in loose clusters from June to October. This white wood aster originally from North America was a favourite shade-loving plant of Gertrude Jekyll who used it in her own garden teaming it with bergenias. A great plant for a shady border.

Garden care: After flowering cut the flowered stems to the ground and apply a generous mulch of well-rotted garden compost or horse manure around the base of the plant.
