‘Heirloom Cardinal Climber’ Hummingbird Vine Seeds

Cardinal Climber turns summer heat into a vertical show. Finely cut, tropical-looking leaves create a light green screen, spangled with clusters of 1½-inch crimson stars that serve as vivid drinking fountains for hummingbirds.

The fast 8-foot vine is ideal for a sunny trellis, obelisk, or fence where its airy foliage can soften a hard edge without looking heavy. Flowers continue into fall while warm weather holds.
