Leafy Green
White Russian Kale is a frost-tolerant, open-pollinated variety with distinctive white-ribbed leaves that bring both visual appeal and cold-season hardiness to the garden. Ready to harvest in 50 to 59 days from transplants, this compact kale thrives in zones 3 to 10 and actually improves in flavor as temperatures drop into late fall. The white-veined, jagged foliage is a lighter variation of the popular Red Russian kale, offering the same serrated character but with a more delicate appearance. Harvest individual leaves starting about two months after planting, and the plant will reward you with tender, high-quality leaves well into the colder months.

The eating quality of White Russian Kale genuinely improves with light frost, making it one of those rare crops that actually gets better as the season turns cold. Its white-ribbed, serrated leaves are visually striking in the garden and on the plate, and the plant's compact growth habit fits neatly into small spaces. Whether you're after full-size mature leaves at 50 days or younger baby greens at just 20 days, this cultivar adapts to multiple harvest windows, and its frost tolerance means you can extend the season well beyond what most greens allow in cold climates.
White Russian Kale is harvested as individual leaves beginning about two months after planting, a method that keeps the plant productive throughout the season. The young leaves work beautifully as baby greens, ready at just 20 days for salads and tender preparations, while full-size leaves suit braising, sautéing, or incorporating into soups and stews. The variety also performs well as a microgreen, reaching harvestable size in just eight days, making it versatile across multiple production scales and kitchen applications.
Sow 2 seeds per cell in 50- to 72-cell plug flats, or 3 to 4 seeds per inch in 20-row flats at a depth of 1/4 inch. Keep soil temperature above 75°F (24°C) until germination, then reduce air temperature to about 60°F (16°C). Seedlings should be ready to transplant in 4 to 6 weeks.
Transplant outdoors when seedlings are 4 to 6 weeks old, spacing plants 12 to 18 inches apart in rows 18 to 36 inches apart. Kale prefers cooler growing temperatures of 55 to 75°F, with optimal growth at 60 to 70°F.
Beginning about two months after planting, harvest by clipping individual leaves rather than removing the entire plant. This selective harvesting keeps the plant productive and allows continued leaf production throughout the season. The eating quality will improve into late fall with light frost, so delay harvesting until after the first cold snap if you can, as this enhances flavor and tenderness. You can also harvest much younger leaves for baby greens at around 20 days, or as microgreens at just 8 days if preferred.

“White Russian Kale emerged as a lighter-veined sibling to the ever-popular Red Russian kale, maintaining the same jagged, tenacious leaf character but in a more delicate color palette. The exact origins of its initial cultivation are not fully documented in available sources, though it represents the broader Russian kale family that became a staple of cold-climate gardening. As an open-pollinated variety, it has been preserved and passed along by gardeners who value both its visual appeal and its remarkable ability to thrive when other crops fail in harsh conditions.”
