Mammoth Red Rock is a large, late heirloom red cabbage grown since the late 1800s for its unusually big, deeply colored heads. Unlike compact early red types, it produces solid round heads of six to eight pounds with rich purple-red leaves throughout. It is a main-season to late variety that sizes up over a long growing period and stores well, retaining its vivid color in the cellar. The bold pigment makes it a striking addition to salads, slaws, and pickles, and the heads are firm and slow to split. Mammoth Red Rock needs generous spacing, fertile soil, and steady moisture to reach full size, rewarding patient gardeners with large, colorful heads for fall and winter use.
