Kennedia nigricans is a vigorous, trailing or climbing perennial plant native to southwestern Australia, prized for its deep purple to almost black pea-like flowers. Belonging to the Fabaceae family, it produces lush, trifoliate green foliage that provides a dense, attractive backdrop for its blooms. The flowers typically appear in spring and summer, making it a popular choice for ornamental gardens, trellises, fences, or rockeries. This species prefers well-drained soil and a sunny to partially shaded position, and it is moderately drought-tolerant once established. Kennedia nigricans also has nitrogen-fixing properties, which can improve soil fertility, and it is valued for its ability to cover ground quickly or climb structures while offering a dramatic floral display.
