Hydrangea Macrophylla x Paniculata 'Princess Diana' WOWTime®

Double, star-like blooms
This is a new plant said to be part macrophylla and part paniculata but hard to see anything but those blooms! Wow is right for this plant with a great compact nature with strong stems and leaves will hold up this unique colorful blooms. Flower color is dependent on the pH (shown pink here) but we're excited to see the rich blue it will become.
