Hydrangea arborescens 'Haas Halo' (smooth hydrangea)

Considered a top performer in Mt. Cuba Center's Hydrangea trial, 'Haas Halo' offers a wonderful blend of beauty and pollinator value. It offers an upright habitat with large lacecap flower heads. It blooms from mid-June to early July and grows to about 7 feet tall and wide, with 8 inch blooms. It will grow best in moist to occasionally dry soil in full to part sun. It is believed to handle the heat and humidity better than some other smooth hydrangea cultivars. These large lacecap blooms are highly attractive to bees and butterflies and complement the deep bluish green leaves.
