HOW TO GROW SIBERIAN KALE
Start indoors 4-6 weeks before last frost, plant out 4 weeks before frost. For fall harvest, transplant 13 weeks before first frost, without additional protection. In a hoophouse, you can plant 2-3 weeks later. Plants are hardy when small but may not feed you until spring. Direct sow anytime after last frost up to 6 weeks before first frost. For seed production, plant in late summer in the Pacific Northwest and coastal British Columbia for a more cold hardy plant. Becomes sweeter with frost and edible to about 22–25˚F. Survival at low temps 10˚F or cooler requires good mulch or snow cover to protect from wind freeze. Will cross with rutabagas. Row covers reduce cabbage worms and extend winter harvest. Soil pH 6.1-6.5. Hardiness zones 3-9. Biennial.

Frank Morton’s first award winner, selected among the top 5 Best New Vegetable Introductions of 1997 in the National Gardening Trials. Combines the broadleaf frills of ‘Siberian’ with the color of ‘Red Russian’. Great raw flavor for salads, especially the young mature leaves of full-grown plants. Gives good fluff to flat salad. Bolting purple stems of overwintered plants are very sweet, colorful, and heavy salad items—also perfect for light cooking or stir fry. Exhibits Clubroot tolerance.

Wild Garden Seed
Certified Organic by Oregon Tilth
Seed grower since 1994
Karen and I began Wild Garden Seed in 1994 at the same kitchen table where her laptop is sitting now. The seed business was an adjunct to our Wild Garden Salad business until September of 2001, when we left salad selling behind and rededicated all of our energies to making a livelihood as seed growers, breeders, and sellers. There were some very tough years there. In 2002 we began a joint venture with our friends John Eveland and Sally Brewer, owners of Gathering Together Farm, to grow and sell organic seed under the Wild Garden name. Gathering Together Farm provided the infrastructure, means of production, and home office services, Shoulder to Shoulder Farm provided the seed management, processing, research, and marketing. We shared many complimentary farm functions over the years: the insectary benefits of diverse flowers in a long period of blooming, the harvest synergies of biennial crop production together, peaks and ebbs in farming cash flow, and seasonally opportune infrastructure sharing. All of these made the farm function better and helped lift Wild Garden Seed into a self-sustaining, farm-based seed enterprise with an international reach. We sold seed to 41 countries in 2014, our 20th anniversary.
