Wooly Shower Orchid Bush. The actual flowers are tiny and inconspicuous, but they are borne in the center of three showy white 1in long bracts that look like velvety propellers. The bracts gradually change through pink, lavender, and finally gray over the course of several weeks. Stunning Bracts: showy, silver-pink "wooly" bracts that surround small, inconspicuous flowers, creating a cascading effect. A fast-growing, woody vine that can quickly cover trellises, arbors, or fences with its dense foliage. Prefers full sun to partial shade and thrives in warm, humid climates, adding a touch of the tropics to any garden.
