‘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. tomentosum plants. 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.
