Pearlbrush (Exochorda) is a small genus of deciduous shrubs from China and central Asia, grown for their spring show of white flowers; common members include E. racemosa and the hybrid 'The Bride'. The key to growing them is full sun and well-drained soil, as they are grown for their pearl-like spring blooms.

About

Exochorda is a small genus of flowering plants in the family Rosaceae, native to China and central Asia (Turkestan). They are used as ornamental plants with the common name pearl bush, or pearlbush. Numerous species have been described on the basis of differing appearance and geographical separation, but a systematic study revealed that the different types are closely related and probably all descended from a single species that formerly had a wide distribution that has been fragmented by habitat loss. As a single species the correct name is E. racemosa.

How to grow it

A valuable garden hybrid is known as E. × macrantha C.K.Schneid. or Exochorda 'The Bride'. Lemoine's catalog of 1904 [as cited by C. K. Schneider, translated by Wikipedia] stated "We obtained this hybrid by fertilizing E. alberti with pollen from E. grandiflora. The clusters of flowers which terminate each shoot, are erect or horizontal, each one with 8 to 10 large flowers, well opened and unfolded, snow white. This new shrub has the vigorous growth of E. grandiflora. As an isolated specimen the effect is magnificent." This plant has gained the Royal Horticultural Society's Award of Garden Merit.
