White Russian

Family: Brassicaceae Vegetable

Velvety leaves unfurl in a cool, luminous palette—White Russian kale brings a crisp, fresh crunch with a gentle sweetness that lingers like spring air.

The foliage forms an upright, richly textured rosette of tender, medium-to-large leaves, ideal for repeat harvests as new growth keeps coming. Grow it for bold, leafy salads and vibrant sauté-ready greens, or blend into smooth sauces and hearty soups for a garden-to-bowl staple.

Culinary Notes

Chef's Note

White Russian kale has a tender, velvety texture with a gentle sweetness that plays nicely in raw preparations—so it won’t turn leathery when you dress it lightly and move fast. When cooked, it wilts without collapsing, making it ideal for quick sautéing or stirring into beans and broth for a green that stays chewable.

Best Uses

raw massaged salads where it stays snappy and not too tough
quick sauté or wilted greens for a bright, clean mouthfeel
thick soups/stews where it keeps color and chew
smooth green purées/pestos that benefit from its mild sweetness

Flavor Profile

crisp, cool crunch gentle sweetness mildly bitter, leafy finish tender velvety bite

Frequently Asked Questions

Why are my Brassica oleracea (“white Russian” kale) leaves getting holes and damaged edges, and what should I do?

Holes with ragged edges are most often from cabbage worms/cabbage loopers or flea beetles (both are common on Brassica oleracea). Hand-pick caterpillars early in the day and spray Bacillus thuringiensis (Bt) on the undersides when larvae are small; for flea beetles, use row cover from seeding until plants are well established and remove weeds that host pests. If damage is severe, reapply Bt after 5–7 days and keep foliage dry enough to prevent secondary issues like leaf spots.

How often should I water Brassica oleracea during the main growing phase, and what soil moisture level is best?

During active leaf growth (about weeks 3–7), keep soil consistently moist but not waterlogged: aim for roughly 1 inch (2.5 cm) of water per week split across 2–3 waterings as needed. Water at the base early in the day so the leaf surface stays drier, and avoid letting the soil dry out completely between waterings because Brassica oleracea can develop tougher, less tender leaves. If your finger inserted 2 inches (5 cm) down feels dry, water; if it feels soggy or leaves are yellowing quickly, reduce frequency.

When is White Russian Brassica oleracea ready to harvest?

Harvest at about 50 days when heads/leaf rosettes are firm and the leaves are fully expanded but still tender (typically 8–12 inches tall for many home plantings). Pick outer leaves first for a longer harvest window, cutting cleanly with a knife about 1–2 inches above the crown; stop before the plant becomes woody or leaves turn overly coarse. If growth slows and leaves thicken rapidly, harvest promptly to maintain the best flavor and texture.
