Hydrangea macrophylla 'PIIHM-I'

Hydrangea macrophylla ‘PIIHM-I’

For a species whose susceptibilty to winter dieback resulted in a never-blooming cycle of endless dissappointment, Endless Summer® hydrangea are a game changer. They were developed because of their ability to bloom new growth (instead of just old). Now, despite dieback, this plant yields flowers with pink coloration in alkaline soil and periwinkle blue hues in acidic soil. A late summer colorful anchor for shaded areas. As blooms fade, they contrast nicely against the fall foliage shift from deep green to burgundy-red.
