Jeok Gat Korean Red Mustard Seeds – Deep Purple-Red Leaves, Spicy & Tender, Microgreens to Pickling, 40–50 Days

Jeok Gat – Korean Red Mustard (Brassica juncea)

Jeok Gat is a strikingly beautiful and deeply flavorful mustard variety popular in Korea and North China — vigorous, fast-growing, and extraordinarily versatile. Its leaves are a rich, deep purple-red with ruffled edges and a contrasting green mid-rib, making it one of the most visually dramatic greens you can grow. Young leaves are thick, tender, and delightfully spicy with an excellent bold mustard flavor. Mature leaves develop more complexity and intensity, making them ideal for pickling, cooking, and juicing.

Harvest at any stage — from microgreens at 7–14 days, to baby leaf for salads, to full maturity at 40–50 days for pickling and stir-fries. A versatile cut-and-come-again green that thrives in cool weather and performs best in mild climates. Flowers and seed pods are also edible.
