Besides basic red beets, nurseries and garden catalogs offer seeds of golden yellow and white varieties. The tender young leaves are edible. Sow in early spring (or in late summer, for a fall crop). Plant seeds 1 inch apart in rows spaced 1½ feet apart, or broadcast them in wide beds; thin seedlings to 2 to 3 inches apart. Harvest 45 to 65 days after sowing.
