Growing Notes

The vining foliage likes something to grow on, so place it near another plant for structure, give it a little arbor or arch of bamboo, or just let it cascade out of the pot.
Prune off the vine in summer once it has dried completely, or not.
If grown from seed the caudex will grow much faster if left submerged under the soil, but the characteristic deep corking that makes these plants sought after only developed after they are lifted above the soil.

Special Interest

Another common name for this plant is Hottentot bread, referring to the edible nature of the caudex, which is used as a staple in South Africa by native populations. Being a dioscorea it is basically a sweet potato!

Dioscorea are high in steroids and at one time trialed as a commercial crop for this use.
