I would like to grow these wonderful sweet potato here in Nevada. We ate them in New Zealand and they are beyond good.

I found Kumara at Whole Foods in Encino, but they had them labeled "Japanese Sweet Potato." If I hadn't just seen them on a trip to NZ, I never would have known! Hope it helps.

I also long for NZ Kumara, and have been unable to find them in the states. Where can I order tubers for growing or for eating? I'll start a greenhouse if needed. Thank you.

I would like to try to grow kumara potatoes in our green house as you say they need a long growing season. Can you advise me where I can buy tubers/seeds? Many thanks Graham

I get my slips from Pioneer Garden and Seed in Villa Park IL. I grew sweet potatoes for two summers with great harvests. I am not sure why they say 5b is not good for sweet potatoes.

I ate kumara everyday when visiting NZ and loved it! Because it was less sweet than USA sweet potatoes. I am craving it and need to find out how and if I can get seeds and grow it in Virginia? Would love your help on this!
