Siberian kale, scientifically known as Brassica napus, is a hardy heirloom leafy green celebrated for its exceptional cold tolerance, tender texture, and mild sweet flavor. This resilient variety thrives during cool weather and is especially valued for extending fresh garden harvests well into fall and winter when many other crops struggle.
The broad slightly ruffled leaves possess a tender texture and delicate sweetness that make Siberian kale wonderfully versatile in the kitchen. It performs beautifully in fresh salads, soups, stir-fries, smoothies, sautés, and countless cooked dishes while still maintaining excellent texture and flavor. Young tender leaves are especially prized for fresh eating.
Growing Siberian kale is straightforward and rewarding for gardeners of all experience levels. This adaptable variety thrives in fertile well-drained soil with full sun but also tolerates partial shade, making it suitable for a wide range of growing conditions. Sow seeds directly into the garden in early spring or late summer for dependable cool-season harvests. Regular watering and occasional fertilization help support vigorous healthy growth throughout the season.
Cold hardy, nutritious, and highly versatile, Siberian kale remains one of the finest heirloom kale varieties for gardeners seeking dependable harvests and exceptional cool-season performance.

How to Save Seeds
Most kales belong to the Brassica oleracea family, which includes broccoli, cabbage, kale, and Brussels sprouts, so isolation by approximately one mile is recommended for maintaining seed purity.
Siberian kale is an exception because it belongs to the species Brassica napus, meaning it can cross-pollinate with rutabagas and related varieties.
Mulch plants heavily to help them survive winter conditions. Siberian kale will typically flower and produce seed during its second growing season.
Allow seed pods to fully dry on the plants before harvesting and storing seeds in a cool dry location for future planting.
