ually grows as tightly clustered leaves in a compact "head", and maybe a few loose outer leaves around the base.In warmer weather, it flowers. The head splits open and gives birth to a stalk that uncurls itself as it forces the split head farther open. The stalk grows 2-4 ft tall, then branches and develops numerous small, 4-petaled, cross-shaped yellow flowers that eventually develop into elongate seed pods. There are hundreds of cultivars
