General Description

The delicious, sweet, mild turnips of 'Hakurei' are small, pure white and round but slightly flattened. Japanese in origin, this cultivar is very fast-growing, being ready to harvest as early as 35 to 38 days from sowing. This is a turnip for non-turnip lovers to try because its roots are so mild and sweet. The dark green tops also taste delicious cooked or eaten raw in salads.

Some classify turnips in the Rapifera group. Turnip varieties come in many shapes and sizes. The larger the root, the more pungent the flavor. Large turnips are grown for animal fodder. These annual or biennial, cool-season plants form loose basal rosettes of broad fleshy green leaves with rough hairs and long stalks. The leaves may be deeply lobed or violin-shaped. Turnips have round to oblong fleshy taproots of white or yellow. Tall sprays of bright yellow flowers appear in spring or summer, often in the second season of growth. Rattlebox seed capsules follow, opening to scatter many reddish-brown to black seeds. The seeds may also be used to make mustard.

These cool weather crops prefer full sun and moderately fertile, humus-rich, neutral to slightly acid soil with ample drainage. They generally mature quickly, from 50 to 80 days depending on variety. Sow them in early spring before temperatures heat up or in late summer for fall harvesting. In areas with mild climates they make an excellent winter crop. Hot weather or prolonged chilly spells may cause them to flower ("bolt"), which usually results in bitter-tasting, dwindling plants. These brassicas are frost hardy and many will take a few degrees below freezing. They are not heavy feeders and may not need fertilizer if grown in rotation with nitrogen-fixing legumes. Some are shade-tolerant and good for planting between taller vegetables such as corn. These wonderful, variable greens are generally easy to grow and very tasty.
