Hydrangea macrophylla Pistachio

Prized for its kaleidoscopic blooms, Hydrangea macrophylla Pistachio is a compact, bushy, deciduous shrub boasting a profusion of multi-color domed flower clusters in shades of chartreuse green and hot pink. Colors will vary depending on the pH of the soil, being more blue in more acidic soils. Blooming on both old and new growth, this reblooming hydrangea flowers consistently and provides gorgeous flowers all summer long, as flower buds are produced not only in the fall but also in spring and summer. The flowers are borne above the handsome foliage of broadly ovate, toothed leaves. Pistachio hydrangea is great for small gardens and is the perfect size for patio containers.
