Southern Giant Curled is a traditional Southern mustard green with frilled leaf margins and a robust spicy flavor. Mustard greens have been cultivated in Asia for thousands of years and in the American South since the colonial era.
Mustard greens are absurdly easy in the PNW — they germinate in cold soil and grow fast. Southern Giant Curled is a classic variety with ruffled, bright green leaves. Sow in early March for April/May harvest, then again in late August for fall. The heat level varies by growing conditions — cool, well-watered plants are milder.
Direct sow in early spring (March) or late summer (August-September). Sow 1/4" deep, 4 seeds per sq ft. Mustard is fast — 21 days for baby greens, 40 days for full size. Thin to 4-6" apart. Keep moist — drought stress makes leaves intensely hot and tough. Harvest outer leaves or cut whole plants at 4-6" for baby greens. Mustard bolts quickly in heat — spring plantings are best harvested by late May; fall plantings produce through winter in mild years. Mustard greens have a spicy kick that mellows with cooking.
