Description:

South Anna is a new Downy Mildew resistant butternut developed from a cross between Seminole Pumpkin and Waltham butternut. Edmund Frost made the cross in 2011 and has been working on it each year since, intensively selecting for Downy Mildew resistance, productivity, eating quality, brix, dry matter, keeping quality, and butternut shape. This is F7 seed (the seventh generation after the cross). While selection work will continue through 2018 and 2019, the progress made to date is exciting. Expect 95% butternut-shaped fruits, with good productivity, Downy Mildew resistance, rich sweet flavor, and very good keeping quality. Immature fruits vary between light and dark green in color (most immature butternuts are light green). The dark green 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 Downy Mildew comes early, and provide higher yields in years with average DM pressure. The healthier foliage also leads to better fruit quality, with sweeter, riper fruits of a rich tan color. When used as a late planting, South Anna grows strong until frost, allowing for later harvests that will keep better into the winter and spring.

South Anna is an Open Source Seed Initiative (OSSI) variety. OSSI is a movement to help protect seed from corporate monopolization. Read more at osseeds.org.

    How long are the vines? Because my garden is small, I trellis all of my vining crops. But I learned the hard way that some squash vines can grow 50 feet long - way too long to trellis!

    • These have long vines. It would take a very strong trellis, such as a cattle panel arch. On the flat I use 9 foot row spacing. Don't be shy about training or cutting vines that are starting to go where you don't want them to.

    hello, i would like to cross my tromboncino squash with your seminole x waltham (i'm looking for a long skinny squash that tastes like butternut when mature). i don't know the longevity of squash pollen, but if you'd want to send me some pollen, i would be more than happy to send you some F1 seeds back in exchange (if the pollen happens to survive the trip.) thanks!

    • I don't think the pollen would make the trip, though I've heard you can keep a male flower in the fridge for a couple days.
      We have some seminole pumpkin that crossed with tromboncino accidentaly, so maybe I'll look into that, starting with some attempts at self pollination (its getting late in the season) and then some taste tests of the cross. I also have a couple seminole-waltham plants with long skinny necks that I could work with (if they do decently on eating quality tests).
      Thanks for the offer and the idea. Edmund for cwsg commonwealthseeds@gmail.com

    How many squash do I need to save seeds from to maintain genetic vigor in future generations? I have about 25 plants that are all doing great! Is that enough to maintain genetic diversity and strength or would it be beneficial to buy more seeds to plant next year alongside the seeds I save from this year? Thanks for such awesome seeds!

    • Elisha,
      Since this is a variable population its ok to save seed from only your favorite few plants and to keep selecting from there each year to get (or maintain) what you want. (In a stable variety I would recommend at least 10 cucurbit plants but I think even then you can get away with less for a generation or two). Each Seminole-Waltham plant has a lot of genetic variation in it at this point. Also, each fruit has seeds whose male parents are many or all of the plants in the patch. Cucurbits do not have much inbreeding depression like corn or broccoli. In fact, many cucurbit varieties have been bred using repeated self pollinations of single plants (though many lines are tried during this process). This technique narrows the genetics much more than selecting from fruit that has multiple male parents. Some breeders believe that incorporating more plants and more genetics will yield a more resilient variety however. In any case if you're not self pollinating and you're saving seed from a few favorite plants there will be plenty of genetic diversity maintained here.

    Edmund, I am getting a good harvest. Some of the baby squash are dark green with butternut shape and some are light green with Seminole pumpkin shape. They are charging through Downey mildew that has killed the Waltham butternuts. Tromboncino and Palav Kudu are also not bothered by mildew. All other cucurbits are dead!

    My first planting of these failed to germinate due to cool wet April conditions, Replanted May 9 and have 2 fruits both very dark green and looking like Seminole pumpkins, Just letting you know, no butternut shapes yet.

    • I now think I mixed these with another squash seed. Mine have classic young butternut coloration.

      Further Internet research shows pics of the same dark green color in immature Seminoles so gues I will wait and see if they ripen to butternut tan. I'll say this, they have taken over the trellis going up 6', back down and over three rows!

    Does Seminole Waltham winter squash need to to have something to climb up? And how much space between plants?

    Posted by Debra Cox on 05/10/2015

    Answers 1

    • Two to three feet between plants and nine feet between rows.... While they will climb all over the place, they can be grown on the flat.

    Is this seed the F3 from an F2 selection, or is it the F4 from an F3 selection?

    Posted by Deirdre Birbeck on 04/08/2015

    Answers 1

    • This seed was selected from F2 generation plants in 2013. We planted and observed the F3 generation in 2014, and entered it in our winter squash variety trial. We have F4 seeds currently (selected from the F3 generation) but not enough to sell. Next year we should have F5 seed for sale (in bulk as well as packet sizes).
