'Evangeline' was developed at a horticultural research institute in Louisiana and has Intellectual Property Rights. This means that it could only be available to commercial growers who probably pay a royalty for the slips for their crops. You could try the Sweet Potato Research Station at: PO Box 120, Chase LA 71324. These restrictions seem onerous for home gardeners but help pay for the development costs for new varieties. Try them, they may be willing to send you a few slips.

Thanks for that, but I also remember some Maori potatoes being very similar also to the look of this type I ate..my ex use to grow a lot of heirloom veges and it looked similar to what hr grew back then... Might buy 1 again and grow it to see how it grows...as a vine or an up right plant.

Hi there, I bought a bag of mixed kumara & in it was 5 varieties & 1 was a purple fleshed purple kumara. I think its maybe a relative of potato.. as I am allergic to nightshade family & on eating 1 of these set my tongue and throat tingling, spat it oit and rinsed my mouth out.. any ideas!?

Potato is a member of the Solanum (nightshade) family while kumara (sweet potato) is a member of the Ipomoea family which includes other plants such as Morning Glory, a totally different Genus.The purple 'kumara' may have been a knobbly potato packed with the others by mistake.

Log onto - www.kumera.co.nz for a list of varieties. If you contact them they should be able to help you. Sweet potato is very easy to grow from cuttings. Just put cuttings into a jar of water and they will soon grow roots, then plant them. All the best.

Do you cut the end of runners off
09 Feb 17, John (Australia - temperate climate)
You certainly can cut the runners back. Kumera/sweet potato is a member of the same family as the blue flowered Morning Glory vine and needs containing to stop it spreading. Do not cut it back too hard as the leaves are also feeding the plant. the runners will form more sweet potatoes where they are in contact with the ground and can form roots. You could also put a stake in when you plant them next time and tie all of the growth to the stake then at the end of the season cut the growth off, let it dry and use it for mulch or compost. Trust this helps.

You can eat the tender shoots like spinach!

When is the best time to plant sweet potato for Adelaide, S.A.? I have grown them in the past and only got a few as Curl Grubs ate the rest of my produce, they were planted in a raised bed.
