Noted for its long-lasting flowers, Hydrangea macrophylla 'Amethyst' is a compact mophead hydrangea with large and bold, rounded flower heads, packed with soft pink or pale violet-blue florets, depending on the soil pH. Blooming from early to late summer, the remarkable blossoms age to reddish pink with lime green markings and last for weeks in their final color, lime green. The foliage is medium to light green with large, glossy, serrated leaves. 'Amethyst' is perfect to create a low hedge and lovely in containers.

- A sun to part shade lover, it is best grown in rich, medium moisture, well-drained soils. Full sun is tolerated if constant moisture is provided.
