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."

First time growing these, planted this spring.
I did a little row of it, they grow super fast huge leaves. Much bigger leaves than the swiss chard I sowed about the same time. Slightly fuzzy, Thin, with a juicy rib like the red mustard I grow. The caterpillars prefer the kale and collards, so these were less hole-y. Tasted OK, I probably need help making my greens more tasty in general. The chickens like them fresh. Very productive in spring, but have gone downhill fast through July. Too hot? Too much rain? Shade from cucumbers? I just don't know. Updating in October- some survived and started growing again, plus I sowed some fresh seed. They are growing fast again.
Update following March - some survived our mild winter and are bolting, just as RicCorey described them, will submit a picture.
