Brassica napus 'Red Russian'
vegetableRed Russian is a tender Siberian-type kale (Brassica napus, the same species as rapeseed, rather than the curly Brassica oleracea kales). Its flat, oak-shaped, blue-green leaves carry striking purple-red midribs and stems, and the texture is notably more tender and the flavor milder and sweeter than curly kale, making it the best choice for raw salads and massaged-kale dishes. Fast-growing and very cold-hardy, it produces baby leaves in about a month and full leaves in 50 to 60 days, sweetening further after frost.

Hardiness Zones
Zones 3 – 9

When to Fertilize
At planting and every 4 to 6 weeks
Fertilizer
Nitrogen-rich or balanced 10-10-10
Direct sow Red Russian 1/2 in. deep as soon as the soil can be worked in spring, or start indoors 4 to 6 weeks before the last frost and transplant 2 weeks before it. For a fall crop, sow in mid to late summer. Thin or space plants 12 to 18 in. apart in rows 18 to 24 in. apart; sow closer and harvest young for baby-leaf salad mix. Grow in full sun and rich, well-drained soil with steady moisture. Feed with nitrogen for fast leafy growth, and harvest the outer leaves regularly to keep the plant producing.

Proactive ways to stop trouble before it starts — tap a name with an arrow for its full guide
Cover with floating row cover from transplant, handpick green caterpillars, and treat heavy pressure with Bt
Row cover excludes the moths; Bt controls larvae if they get established
Hose off colonies on leaf undersides and plant dill or alyssum to draw their predators
Row cover on young plants stops the shothole feeding; flea beetles ease off as plants size up
Handpick the shield-shaped bugs and their barrel-shaped eggs, and clear brassica debris in fall
Pick Red Russian as baby leaves at about 30 days for salads, or let leaves reach full size at 50 to 60 days. Harvest the outer leaves first, snapping them at the base, and leave the central growing point so the plant keeps producing for months. Flavor turns sweetest after a frost. In mild zones it overwinters and offers tender spring shoots before it finally bolts.
Kale is one of the most nutrient-dense vegetables grown: a single 100 g serving supplies several times the daily requirement of vitamin K, large amounts of vitamin A as beta-carotene, and around 90 to 120 mg of vitamin C, plus the eye-protective carotenoids lutein and zeaxanthin and useful calcium. Red Russians purple pigments add anthocyanins on top of the standard kale profile.
