Hydrangea arborescens ‘Haas Halo’ #3 (Smooth Hydrangea)

‘Haas Halo’ is a cultivated variety of our native Smooth Hydrangea (Hydrangea arborescens). This selection has huge, creamy white, 14″ lacecap flowerheads which are borne on upright stems that do not let them droop to the ground. The flowers are extremely popular with pollinators! These upright, mounding, deciduous shrubs prefer a partially shaded site, but perform nearly as flawlessly in full shade despite the decrease in flowering. A full sun exposure will produce the heaviest flowering, but a consistently moist soil is necessary. Blooming occurs on new wood, so pruning should take place from late fall to early spring. They can also be cut to the ground in winter to control the size.

‘Haas Halo’ was rated as the best preforming native Hydrangea cultivar in Mt. Cuba Center’s Native Hydrangea trial!
