Hello can you grow Oca in the tropics maybe during the cooler drieronths? No frost up here, just concerned about planting in the wet season as its ver hot 35 degrees plus most days.

Hi Malcom, in Tasmania you can usually find oca for sale as providence growers (Salamanca market or roadside stall at Nieka), and sometimes in store when it’s harvest time at hill st, young’s veggie shed and organic grocers.

I am seeking Yellow Yam in Australia. I live in Perth Western Australia. I want to grow the yam for personal use. I think Jamaican Yam is of the plant species in the genus Dioscorea. Are you able to assist please?
