|True potato seed information and growing instructions|
|This mix includes seeds derived from OSSI open source varieties.|
|True potato seeds are breeding seed and germination is not guaranteed.|
Beginning this year, we no longer offer seeds from previous years. Instead, seeds collected over the past five years are all mixed together. There is little difference in germination over five years and this increases the diversity of the mix, while reducing the complexity that we have to manage.
Diploid potatoes are not commonly grown in North America. They are native to the Andes. Diploids tend to be smaller and have lower yields than common tetraploid potatoes, but they compensate for this with richer flavors, beautiful colors, and unusual shapes. There are two very good reasons why diploids aren’t commonly grown in North America: most of them have little to no dormancy, which makes them difficult to store over the winter, and many of them have short day photoperiods, which means that they don’t produce tubers until fall. These deficits are not universal. Some plants grown from this mix will have dormancy and quite a few will tuberize in the summer, although it might take them a little longer than it would in the fall and they might have other quirks like longer stolons when grown in the summer. Still, if you grow a full packet, you can expect to get plenty of plants that will make tubers in the summer.
This mix contains seeds from both low dormancy (phureja type) and high dormancy (stenotomum type) diploids and crosses between the two. The seed parents are plants that I have selected to keep, so they are either heirloom varieties, varieties that I have released, or varieties that I keep only for breeding.
Some people are deterred from growing diploids due to the problem of low dormancy. This is really not such a big deal if you are willing to store tubers in the refrigerator. If you put your seed tubers in the refrigerator right after harvest, most will last long enough for spring planting. The alternative is to just eat them and grow more from seed again the next year. The tubers will be different every time, but that’s part of the fun as far as I’m concerned.
The picture above is an output photo of a full bed of seedlings grown from this mix, so it will give you a pretty good idea of what you can expect. What it doesn’t show are the plants that produce tiny tubers or no tubers or that died early in the season. You will always get some of those when you grow potatoes from seed.
The mix of parents change from year to year, typically by about 20%, so seeds of different years can supply additional diversity. Seeds that are a year old may also germinate a little better than current year seeds.
This mix is also available in bulk packets: one gram packets contain approximately 1,100 seeds and 5 gram packets contain approximately 5,500 seeds.
