Double pink, star shaped flowers

Hydrangea macrophylla Double Dutch™ Alkmaar

Delicate, yet sturdy double pink, star shaped flowers on a beautifully branched, compact plant.

One of three Hydrangeas in the Double Dutch series, Double Dutch Alkmaar opens with star-shaped, double flowers - certain to add a delicate feel to any garden space. A re-blooming mop-head, flowering begins in May/June and continues through the summer months with pink clusters of double florets that cover the plant like a blanket of stars. A unique flower form, coupled with an extended bloom time and strong stems, makes the Double Dutch varieties ideal for container plantings as well as an excellent choice for the garden. Note: Hydrangeas in the Double #Dutch series will vary in color intensity based on the pH of your soil.
