(Clematis) Clematis Huldine is known for incredible floral displays and a vigorous growth habit. The pearly white 3-4 inch flowers are composed of six non-overlapping petals, each featuring three pinkish-mauve central bars on their undersurface. Huldine is considered one of the best reblooming clematis vines. Blooming July through August, Huldine looks spectacular when grown over an arbor where bottom sides of the flowers can be viewed with ease. Plant in full sun, and Huldine provides several weeks of color while attracting butterflies and hummingbirds. Enjoy a vertical display with clematis!
