A favorite of Thomas Jefferson at Monticello and so easy to grow! Just plant some seeds in spring and by August and September they put on a spectacular show covering a fence. Hyacinth Bean the plant with the funny botanical name Lablab purpureus. This variety is a Botanical Interests Hyacinth Bean called “Ruby Moon”. I came to appreciate the plant years ago on a visit to Monticello. Exquisite clusters of amethyst flowers and purple pods it is a dazzling ornamental. All you have to do is remember to drop a few seeds in the ground in spring. Hyacinth bean is a dazzling ornamental with stunning, pinkish-purple flowers and shiny, dark purple pods that stand out against the purple and green foliage. Twining stems quickly climb a fence or trellis, trail across the ground for an attractive ground cover, or spill over container edges. Contains toxins; not recommended for eating.
