  • Pollinator-Friendly
  • Unique Hydrangea
  • Premiere Plant

Some people adore lacecap flowers for their delicate beauty, while others appreciate the pollen for butterflies and bees. This premiere plant, the first ever smooth hydrangea with plum-purple lacy florets, accomplishes both, with strong, wiry stems of a dark ruby hue, that sway gracefully with the wind. Imagine big drifts, flowing through a Piet Oudolf-style garden, and come winter, frosted diamonds and songbirds adorning tawny crowns.

Soil Grows well in most soils; avoid wet and poorly drained sites. Mulch is recommended in the landscape.

Pruning Blooms on new wood - cut back by about one-third its total height in early spring, just as the new growth begins to emerge on the stems. Smooth hydrangeas may be cut back harder, however, this prevents woody cells from developing, prohibiting the plant from achieving its maximum stem strength.

Uses Versatile and showy, smooth hydrangeas offer dozens of landscape applications: foundation plantings, perennial gardens, hedges, cut flower gardens, naturalizing, pollinator and wildlife gardens.

Growing Tips We recommend full sun for smooth hydrangeas in the cooler end of its hardiness range; afternoon shade is a good idea in warmer climates, however. The flower color of smooth hydrangeas is not influenced by soil chemistry. Makes an excellent cut flower, both cut and dried.
