How does the air potato spread?
Air potato is a vigorously twining herbaceous vine, often arising from an underground tuber. It produces large numbers of bulbils (aerial tubers), which facilitate its spread and make it extremely difficult to eliminate because new plants sprout from even very small bulbils.
Can I eat air potato?
The edible air potato, or “winged yam,” does grow wild here and there in patches across Florida. Both the hanging “air potatoes” and the roots beneath the ground are edible. The edible type is called Dioscorea alata.
What kind of soil does an air potato need?
Aerial potato produces tubers in leaf axils on the vine and these are large enough to harvest as well as the tuber in the ground, but they are less productive than winged yam. To grow them you’ll need compost rich, freely draining soil. I grow my best by planting them in a hole dug two spades deep backfilled with home-made compost.
How are air potatoes related to white potatoes?
Despite the name, they’re not related to white potatoes (Solanum tuberosum), which is in the nightshade family (Solanaceae). Air potatoes are a member of the yam family (Dioscoreaceae). In Florida you still don’t want to eat them. Both the underground tubers and aerial bulbils may contain a variety of toxic compounds.
How does an air potato resprout in the winter?
It typically climbs to the tops of trees and has a tendency to take over native plants. New plants develop from bulbils that form on the plant, and these bulbils serve as a means of dispersal. The aerial stems of air potato die back in winter, but resprouting occurs from bulbils and underground tubers.

What does the air potato do to the ground?
Tubers underground and bulbils in the air serve the plant as food-storage spaces and as reproductive organs. Grabbing a vine to rip it out of the ground sends the bulbils flying and disperses the seed, even though it’s not really a seed. Nevertheless, even a tiny bulbil that falls to the ground is a new plant waiting to sprout up and out.
How big does an air potato plant grow?

What does an air potato spud look like?
Air potato bulbils resemble miniature spuds but are actually modified branches that are aerial tubers. Tubers underground and bulbils in the air serve the plant as food-storage spaces and as reproductive organs. Grabbing a vine to rip it out of the ground sends the bulbils flying and disperses the seed, even though it’s not really a seed.
