Viburnum Summer Snowflake
‘Summer Snowflake’ is an upright cultivar that matures to 5-8’ tall (infrequently taller). Leaves, flowers and fruits are typically smaller than those found on typical f.tomentosumplants. White lacecap-like flowers bloom in spring (late April-May), but continue to bloom sporadically through summer (hence the cultivar name) and sometimes into early fall. Fruits, a few flowers and autumn foliage color may all be simultaneously present on shrubs in early fall. Introduced by the Canadian Ornamental Plant Foundation.
