I am also trying to find out if there is such a thing as kumara "seeds" and where they can be found?

Annie...We simply bought a small kumara from a local supermarket, suspended it with toothpicks in a cut off coke bottle of water. When the shoots, or "slips" began to sprout (2-3wks) we then placed them in a small jam jar of water until roots began to develop, then planted out in fish bins of potting mix. We were late- late Dec & Jan, have just harvested. A lot were long & skinny, but perfect for the hot air cooker & crockpot. Some were like the shop sizes! We ended up with about 3-4 kg from a single 300g kumara (it's still growing sprouts on the laundry windowsill)! Hope this helps someone out there. Best wishes...

If your lucky you can find some at local garden places for tipu which you can grow out of the kumara tubers by place half of it into water.. they should grow stems/vines which you can snap off & placing those into water to help roots grow... or just cut sections of the tuber off..... but when planting them... they need that late spring early summer heat. Then harvest around now or when frosty etc...... just my 5 cents here lol

Australian Seeds in Western Australia list a native sweet potato - Ipomoea costata but I don't know of any suppliers of seeds of the popular varieties. They are grown from cuttings as they establish quickly and will yield in their first season. Seedlings would probably take another year.
