Botanical Name

SYRINGA x hyacinthiflora 'Blanche Sweet'

Plant Common Name

Early-flowering Lilac

General Description

One of the earliest-flowering lilacs, Syringa x hyacinthiflora is the hybrid between common lilac (Syringa vulgaris) and the East Asian native Syringa oblata. Selected in 1981 by lilac guru John Fiala, 'Blanche Sweet' bears large conical clusters of fragrant chalky-blue, pink-tinged flowers at its branch tips from early to mid-spring, a week or more before common lilac blooms. It forms a rather open medium-sized shrub with oval mid-green leaves.

Plant this shrub in full to partial sun and well-drained mildly acidic to mildly alkaline soil. It is most floriferous and least lanky in full sun. It requires relatively chilly winters and moderate summers to grow and flower its best. The early blooms may be damaged by late freezes. Although relatively resistant to powdery mildew, it may develop symptoms in humid droughty weather. Mass 'Blanche Sweet' in screens, windbreaks or hedges, or use it singly in a shrub planting or mixed border. It is ideal near a path or patio, where its perfumed flowers can work their magic. The flowers are also wonderful in bouquets.
