Growth

Seeds of the purple hyacinth bean

The hyacinth bean grows as a vine, producing purple flowers and striking electric-purple coloured seed pods. Lablab bean is a good choice for a quick screen on a trellis or fence. It grows fast, has beautiful, fragrant flowers that attract butterflies and hummingbirds, and it even produces edible leaves, flowers, pods, seeds and roots. Dry seeds are poisonous due to high concentrations of cyanogenic glucosides, and can only be eaten after prolonged boiling.^[3]
