Hydrangea arborescens ‘NCHA4’ (Incrediball® Blush)

2 Photos


Hydrangea arborescens ‘NCHA4’, is an outstanding result of Dr. Thomas Ranney’s cutting-edge plant breeding at North Carolina State University. As with many pink-flowered cultivars, the coloration of the inflorescences is most intense before the fertile flowers bloom. When the flowers mature, the inflorescence takes on lighter shades of rose but retains some dark coloration on the backs of the sterile flowers. Selected for its compact nature, Incrediball® Blush wild hydrangea formed a 4’ tall by 5’ wide mound, making this hydrangea an excellent choice for gardens with limited space. Cutting back Incrediball® Blush resulted in significantly larger flowers; however, this is not recommended because it led to weaker stems that flopped and broke under their own weight. This trial revealed that, when grown in the mid-Atlantic region, this cultivar performs best in full sun.
