Hydrangea arborescens 'Haas Halo' offers stunning 14 inch wide lace cap blooms with pure white sterile florets surrounding greenish fertile florets. This is a unique form of the species which usually offers just mopheads. The foliage is thick and blue-green. Bushy and upright, with stronger stems to resist flopping and sterile florets that last from June to August, it is a graceful choice. The arborescens group native to North America is exceptionally hardy and easy going but like other hydrangeas requires good moisture to thrive in full sun.
