NANTUCKET BLUE™ BIGLEAF HYDRANGEA
Hydrangea macrophylla 'GRENAN' is commonly known as Nantucket Blue™ Hydrangea. This fantastic, repeat-blooming selection features blooms on new growth throughout its growing season, blooming from early summer to early fall. Flowers are bold with lavender overtones in low pH (acidic) soils and shades of purple to red in higher pH (alkaline) soils. Dense, serrated dark green foliage provides a nice background and turns a nice burgundy red in fall.
Nantucket Blue™ Hydrangea thrives in partial sun and partial shade in rich, fertile, evenly moist, well-drained soils. This selection reblooms on the current year's growth as well as new growth (both new and old wood). Therefore, it is beneficial to prune immediately after flowering to control size and growth. And don't worry if a late freeze nips the flower buds on the old wood, you still have the current year's growth!
