General Information

Vigna frutescens is a herbaceous perennial plant growing from a woody rootstock (the tuber is often 5cm wide). The stems scramble over the ground, twining into the surrounding vegetation for support; they are usually 50 - 150cm long, but can be up to 400cm when supported by other plants. After being cut back by fire, the plant will often start flowering when the stems are only 7 - 20cm long and still erect, before the leaves appear[
