The rough-haired, perennial climbing plant grows very quickly in suitable locations and can cover several dozen square meters there, depending on the climbing base. If it climbs up a tree, the chayote can grow to over five meters high. The chayote forms a rhizome from which it sprouts again in spring in locations with seasons.
The heart-shaped, stalked and simple leaves can grow to the size of a hand, around 15-25 centimeters. The ribbed leaf stalks are around 7-20 centimeters long. The leaves are egg-shaped to round in outline. They have a few small and three to seven large teeth or small lobes on the edge and are usually pointed or pointed. The leaves are hairy on the upper side on the veins. Shoots with dry leaves whose tendrils have not encountered any climbing opportunities often hang from the plant. The bare tendrils have three to five parts. The young leaves are hairy and then become bald.
