Brassica napus 'Red Russian'
Red Russian Kale
Open-pollinated cultivar; the species B. napus originated from a cross between B. oleracea and B. rapa in the Mediterranean/European region
Overview
Brassica napus 'Red Russian' is Red Russian kale (Ragged Jack kale), a cool-season annual forming an upright open rosette 24-36 inches (60-90 cm) tall and 18-24 inches (45-60 cm) wide. Deeply lobed oak-leaf-shaped blue-green leaves with red to purple veining and purple-red stems. The species is B. napus (a natural hybrid of B. oleracea x B. rapa), not B. oleracea like most kale cultivars. The deeply lobed flat leaf shape (like a frilly oak leaf) distinguishes Red Russian from curly kale (B. oleracea var. sabellica) and Lacinato kale (B. oleracea var. palmifolia). The leaves are more tender and thinner than curly or Lacinato types — suited to raw salads. In the mustard family (Brassicaceae). Open-pollinated — seed can be saved. Cold-hardy: the purple pigment (anthocyanin) intensifies after frost. Cool-season crop: bolts in sustained heat above 80°F (27°C). Harvest outer leaves by cut-and-come-again starting at 4-6 inches (10-15 cm), or full-size at 60-90 days. Cabbage worms (Pieris rapae), aphids, and flea beetles are primary pests. Not deer-resistant. Non-toxic (edible crop). Full sun to partial shade. Annual. Growth rate is moderate.
