Hydrangea macrophylla ‘Eternity’ features spectacular, starry, rich pink double flowers adorned with a creamy center. When an individual flower opens, it resembles a lacecap hydrangea with large sterile flowers radiating on the edge. However, unlike the lacecap hydrangea, the inflorescence eventually fills out completely, creating a particularly pretty mophead effect with double flowers. The flower heads are either pink (acidic soil) or blue (alkaline soil). Blooming from mid-spring to early fall, the attractive blossoms are borne on sturdy upright stems, guaranteeing a better display. Compact, this elegant hydrangea makes a fantastic specimen plant and looks lovely in containers. It can be grown as an indoor floral potted plant and is ideal for small gardens!
