Tight, round head of maroon and white leaves. Small, light-jade leaves shaped like baby spinach. Sold in bunches with stems attached. Strong flavor, somewhat bittersweet, but mild enough as the main element of a salad. Narrow, dark green heads of large leaves with firm ribs joined at the bottom.
Outer leaves are larger, darker and softer.
Inner leaves are small, rigid and light green. Strong, peppery flavor. Also, add to sandwiches and creamy soups. Strong, somewhat bitter. Spinach is great on its own or mixed with other greens.
