for those wondering about the cross butternut grizzgal and i referenced. its was/is a hybrid thats been grown out and stabilized into a 'new heirloom'. many people dont understand all heirlooms were crosses at one point and they were grown out by breeder till it stabilized and reproduces true to its self. but anyway point being you can grow it and save seed from it for next seasons going forward.
South Anna Butternut Winter Squash
https://www.southernexposure.com/products/south-anna-butternut-winter-squash/
OSSI variety. (
C. moschata) 100 days. A new Downy Mildew resistant butternut developed by Edmund Frost of
Common Wealth Seed Growers. Stemming from a 2011 cross between Seminole Pumpkin and Waltham Butternut, the final stages of selection are ongoing. Expect excellent DM resistance, productivity and keeping quality, as well as rich sweet flavor. Immature fruits are mostly dark green. These ones take longer to turn fully tan, but when they do you can be sure that they are ripe. South Anna will avoid the crop failure that can occur in years when DM comes early, and provide higher, better quality yields in years with average DM pressure. Can be planted late, allowing for later harvests that will keep better into the winter and spring. Small (3 g) packet has about 23 seeds.
This is an Open Source Seed Initiative variety. The OSSI pledge: "You have the freedom to use these OSSI-Pledged seeds in any way you choose. In return, you pledge not to restrict others’ use of these seeds or their derivatives by patents or other means, and to include this pledge with any transfer of these seeds or their derivatives."
