Anyone here growing edible Air Potatoes? (Dioscorea bulbifera)


Keep us posted! I wanna see how their growth compares in a temperate climate versus the tropics.

My new trellis is already crawling with loads of yams vines, probably too many for the space. The new players on the scene are D. japonica, esculenta, dodecaneura, pentaphylla, bulbifera “Hawaii” and the possible Suavior. All are growing vigorously by now, but the old CV-1 roots I planted haven’t sprouted yet, which leaves me concerned. I was hoping to grow them from last years roots, to get strong vines growing, but if they fail me, I’ll have to settle for first-year vines from my last bulbils.

I placed my two purple alatas at the base of the Açaí palm, where I hope the shade will provide a cooler microclimate conducive to well-pigmented roots.

I’ll take some pics in the coming days, so y’all can see how they’re going.


My bulbifera didn’t sprout leaves yet, it’s just begining, just the polystachya. I live to grow yams, i’m starting to understand them now… i think i lost my alatas from last year. Just hope the ones you sent me this year sprout! :sweat_smile:


My yams growing…

Dioscorea polystacha growing fast…

Dioscorea bulbifera sprouting…


Hello Ceasar! How are you my friend? Do you have dioscorea trifida? In Brazil they call it cará mimoso… Thank’s! :smiley:


They’re looking good!

My D. trifida was a disaster last season. They grow best with space, without competing plants, and I grew all of them in tubs with other hungry plants last season. Most of them hadn’t formed tubers by the time the vines dried. Only one formed a tiny tuber, which I discarded back into its soil because it shared space with some scabby potatoes. I was concerned that it might have been infected with scab, or at least that it might have become a carrier. I sent that soil to my mother’s flower garden, and a vine sprouted there (together with some polystachyas and a potato). I’m not sure I’m comfortable propagating it, but if it seems healthy enough at harvest time, I might be tempted to do so. I’ve been on the lookout for more of them at Walmart (where I bought my original seed piece), but I haven’t seen them for sale since. If my current plant is unhealthy and I don’t find anymore at market, I’ll have to pay a visit to one of the Ag Research Stations, which have this species together with several others. I’ll keep you posted on how things go with this one.


I will update all te situation too, here and on my thread. I bought more alatas on ebay from India and on the italian nursery where i get my plants last year. :sweat_smile:
