Cloak a forlorn fence, trellis, or other sturdy structure with a blooming, evergreen coat! Purple blossoms resembling lovely wisteria blooms decorate this tropical vine in winter and spring. It is not overly vigorous like some vines. It grows to a height of about 6 feet. Thriving in many light conditions, purple coral pea prefers heavy soil, as long as it drains well, and it requires little care after it is established. Prune plants in spring after bloom.
