I think that 2019 will be the last year that we offer this variety. It is a perfectly nice variety, but it is not as good as my more recent selections and also not as easy to use in breeding.
Quinault is the first new variety introduced from our breeding program, grown from open pollinated seed of the variety ‘Rojo’. Mature tubers come out of the ground a light/red purple, sometimes partly tan, but become the darkest red of any variety that we grow after a couple weeks of exposure. Plants are of medium height, usually reaching between five and six feet here by the end of the growing season. The one purpose that this variety is not suitable for is as an ornamental. It is a slovenly looking plant with sprawling stems and droopy leaves. That doesn’t affect food production, of course, but it is a better plant for the back yard than the front.
Quinault doesn’t really measure up to the heirloom varieties. The yield is generally lower and the flavor is fine, but nothing special. The main reason that I released this variety is simply that there had never been a seed grown variety produced in North America and very few anywhere in the world. Quinault will be of more interest to people who are interested in doing yacon breeding than as a general purpose variety. It is early to flower, at about 155 days. It has greatly improved seed set and pollen production compared to the heirloom varieties. Unfortunately, germination rate of the seeds that it produces is lower than most of our later seed-grown varieties (although still superior to the heirloom varieties).
What you will receive:
You will receive the stated number of rhizome pieces, packed in damp peat. You should keep packets refrigerated and check them periodically to make sure that the exposed cuts are not molding. If mold develops, cut back to clean flesh and plant or pot as soon as possible. Rhizome does not store well, so it is always better to plant it than to store it if you can.
Seeds are open pollinated. Because yacon is a polyploid hybrid, the seeds will not grow true to type. They are suitable for use in breeding or conservation efforts and could be used to select varieties similar to the parent type.
