Easily grown in average, medium, well-drained soil in full sun to part shade. Prefers moist loams, but tolerates wide range of soils and has good drought tolerance. Prune as needed immediately after flowering. For best cross-pollination and resulting fruit display, plant shrubs in groups rather than as single specimens.
'Summer Snowflake' is a compact, dense, upright, multi-stemmed, deciduous shrub which typically matures 3-5' tall with a similar spread. Non-fragrant, creamy white flowers in small, flat-topped umbels (to 2-4" diameter) appear in a profuse spring bloom, with sporadic continued bloom occurring throughout the summer (hence the cultivar name). Flower clusters appear in two rows or files, hence the common name of doublefile viburnum. Umbels have a lace cap effect (small, non-showy, inner fertile flowers with a showy outer ring of sterile flowers). Fertile flowers give way in late summer to orangish-red, berry-like drupes which mature to black. Fruits are attractive to birds and wildlife. Ovate, dark green leaves (to 5" long). Reddish to bronze-purple fall color. Fruits, flowers and autumn foliage color may all be simultaneously present on plants in early fall.
No serious insect or disease problems.
