Tyfon (Brassica rapa) is a cross between a stubble turnip and a Chinese cabbage. It was originally bred for forage, and is used as a cover crop and as a compost crop.

However, young leaves are tender, mild and highly nutritious in salad or as greens. Very easy to grow and very fast growing. Best when young and tender. "Cut and come again" at 30-40 day intervals if cut at one inch. Older leaves get hairy and are better cooked as mild greens that absorb other flavors well. If the plant does bolt, the leaves actually get milder, more succulent, and less hairy.

Sow 12" rows in late spring after soil has warmed, and thin to 6" spacing, or broadcast as a cover crop. Tolerates crowding. Prefers full sun and loose, well drained soil with moderate to good fertility, but grows well in any reasonable soil, even heavy clay. Hardy and bolt resistant to 10° F, but will bolt in heat. May overwinter.

Alternate sowing recommendation:
" Plant seed 4" apart 4-6 weeks before the last spring frost or 8-10 weeks before the first fall frost, or later in mild winter areas."
