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.
