General Description

The favorite southern mustard green, 'Southern Giant Curled', is an heirloom cultivar of India mustard, a cool-season annual that originates from Asia. The leaves can be harvested as quickly as 56 days after sowing and are excellent for cooking. This 1935 All-America Selections Winner has remained popular because it’s a good garden performer with excellent flavor. It is also relatively cold-hardy.

'Southern Giant Curled' produces rosettes of large, oval leaves that are bright green and curly. It also produces a large, turnip-like taproot but this is rarely eaten. Warm weather causes plants to "bolt", or produce flowers. Clusters of four-petaled, pale yellow flowers appear atop waist-high stems. Crescent-shaped green pods filled with dark red-brown seeds follow the flowers. The dried pods split open to disperse the seeds.

This is an easy mustard crop for the south. Grow India mustard in full sun and well-drained neutral to alkaline soil. It will not tolerate severe heat or hard freezing temperatures. The leaves are most flavorful when nights are cool. Warm weather causes bitter tasting foliage and early bolting. The best planting times are early spring or late summer or early winter. Where year round temperatures are mild, it makes a great winter crop. To prevent self-sowing, remove the plants once bolting occurs.
