'Haas Halo' Smooth Hydrangea was selected by Rick Ray of Pennsylvania for its extraordinarily large white lacecap flowers. They are produced for a long period in mid summer, and are displayed on sturdy stems which do not flop, unlike many mopheads. 'Haas Halo' is tolerant of full sun as long as good moisture is consistently present, and its 14" flowers make lovely cut or dried flowers. Excellent for a natural look along woodland edges. 2020 PHS Gold Medal Plant!
