Annual Biennial

A cultivated group of biennial plants, selected for its round, swollen root/stem and known and eaten as turnip. Turnips are usually purple at the top and white beneath the ground. Green leaves, covered with short, rough hairs form a rosette-like bunch. They are fast-growing and can be harvested over a long time. Both leaves and the swollen roots are edible. If left grown into the second year, they will form an erect stem bearing bright yellow, cross-shaped flowers followed by elongated seedpods
