Pueraria tuberosa

Pueraria tuberosa, commonly known as kudzu, Indian kudzu, or Nepalese kudzu, is a climber with woody tuberculated stem. It is a climbing, coiling and trailing vine with large tuberous roots. The tubers are globose or pot-like, about 25 centimetres (9.8 in) across and the insides are white, starchy and mildly sweet. Leaves are trifoliate and alternate, while the leaflets are egg-shaped, with round base and unequal sides. They are 18 cm (7.1 in) long and 16 cm (6.3 in) wide and are hairless above. Flowers are bisexual, around 1.5 cm (0.59 in) across and blue or purplish-blue in color. The fruit pods are linear, about 2–5 cm (0.79–1.97 in) long and constricted densely between the seeds. They have silky, bristly reddish-brown hair. Seeds vary from 3 to 6 in number.
