Invincibelle Garnetta® (‘NCHA6’) Smooth Hydrangea comes from the work of Dr. Tom Ranney of NC State University. The blooms appear in early summer, emerging in garnet shades which mature to a good deep pink. Hydrangea arborescens Invincibelle Garnetta® starts blooming somewhat later than other Smooth Hydrangeas, and will rebloom sporadically through the summer, especially if spent blooms are removed. The color is a standout, and the habit is neat and compact.
