This member of the Fabaceae
family was first described by Carl Linnaeus in 1753. It is found on
high altitude in the mountains of Southern North America and Mexico.
It grows in a rich peat with some to lots of sun and plenty of
water. It will, within the first year, get scarlet red flowers. The
vines will reach three metres, the caudex 20 centimetres or more.
It is commonly cultivated in many
parts of the world for its edible seeds and immature seedpods.
