Kale, True Siberian (Organic)

Brassica napus. 25 days baby, 60 days full.

A Siberian type that was recommended to us by Dr. Alan Kapuler of Peace Seeds as a highly productive, hardy kale. A variety that is becoming harder and harder to find. Resembles other Siberian kale types and you can see its relationship with red Russian kale, which is the same species. We think it is the best Siberian kale because it tolerates our Northwest winter weather better than other strains and the plants are big vigorous monsters. Plant size is important when it comes to kale since dwarf types don’t produce nearly as much food. Produces tons of tasty kale raab in the spring. Tolerated water logged soil better than many other varieties.

Seed produced by Deep Harvest Farm on Whidbey Island, Washington.

As required by the Oregon Department of Agriculture and the Washington Crucifer Quarantine, all Brassica family seed lots have been tested and found negative for blackleg (Phoma lingam) by an approved, certified lab.

Geographical Origin


Sow indoors with good potting soil February through September. Transplant about 3-4 weeks after sprouting. In our region, kale can grow through the winter without protection, and survives best when sown in June or early July for this purpose. Alternatively, direct sow March through September.

Seed Saving

To maintain genetic diversity and prevent inbreeding, collect seeds from 10 or more plants of B. napus varieties, or 30 or more plants of B. oleracea. Cut seed heads when pods are dry, place on tarp, thresh by hand or by dancing.  Winnow and screen to clean. Isolate from other Brassicas of the same species by ½ mile.

    Love. This. Kale.


    Where did you grow this variety? Washington

    We love kale–it feels like the backbone of our garden. We’ve been fighting cabbage root maggots, and in the early season, we lost pretty much all our brassicas except our kale plants (thank goodness!). This was our first time growing this kale, and it might be edging out my previous #1 Frilly red russian. The plants are enormous, producing a TON of food. And yet throughout the whole season, the leaves are so tender, almost like a thick lettuce. There are fewer places to hide aphids since they are mostly smooth, and we are eager to see how the summer planted plants overwinter. Absolutely give this a try if you love kale! (Or even just like it.) 🙂

    Where did you grow this variety? Midwestern US

    I started Baltic Red, Dazzling Blue Lacinato, and True Siberian seeds so that I can pop some kale into the ground for the winter once my last round of lettuce is done. I have never had better germination rates than these! I think out of the 40 seeds I started all but 1 seed germinated and all seedlings grew exceptionally fast and vigorous. The seedlings from these seeds actually surpassed the growth of some other kale seeds that I had planted 3 weeks before!
    Overall great quality and I can’t wait to enjoy the kale this winter!
