It may be frigid out there but there are lots of dreams of summer's heat manifest in sweet potato seedlings from last year. Below you'll see sweet potatoes that you have NEVER seen before. Never unless you saw some of my pictures on Facebook that is. Why? Because these are from true botanical sweet potato seed. Each seed contains its own jumbled genes of a unique individual rather than clones of a particular variety (I've got lots of those growing too).
Seedling Sweet Potato Selection
My seedlings from last year (from three seed sources which included seed produced minimally here) were cut. I didn't do it last fall as I wanted to test them for storability under my conditions first. Sweet potatoes are stored warm, by the way, and mine are stored in a wooden chest by a wood stove.
White is apparently semi-dominant, which was certainly the case for my seedlings. White and purple made up the majority of my plants. Purple ones tended toward being longer season or spindly - both of which aren't interesting to me but I did get a few that were exceptional purples/reds with shorter, stouter tubers. I also got a few bronze skinned-white fleshed ones that might be worth growing as I get requests for these sort of starchier sweets quite often.
Most were smooth skinned but as you can see on the right, there were a few that were bumpier. Perhaps this is more common in wild types. White and purple, by the way, tend to be drier and less moist making them better for certain types of recipes like chipping and stewing. I did get two oranges within 2017's seedlings. The pale orange that you can see here and a stouter, shorter darker orange.
I sorted the sweet potato seedlings by form, colour and podding ability first then tasted some of the more interesting ones. The best seedlings were put in a tray for slipping.
One of my favourites was a red skinned, red-purple fleshed one with good yield. We'll see how it does this year!
Last year, I instructed two partner farmers as part of the West Carleton Calorie Project to look for and gather seeds for me. Myself and Our Farm had success so these seeds have been started for this year's trials!
I look forward to comparing yields with 2017's seedling tubers and common short season cultivars like Covington, Beauregard and so forth.
Hoping for a little luck and summer sun to keep this project rolling into 2018.
