The story

Broccoli was bred in Italy from wild cabbage, probably in Calabria, and Roman gardeners grew it; Italian immigrants brought it to America, where it was rare until the 1920s. It is a cool-season crop that sulks in heat.

Planting

Full sun and rich soil; set out plants in early spring and again in late summer for the better autumn crop, 18 inches apart.

Growing

Water steadily, feed with compost, and mulch. Cover against cabbage worms. It tolerates frost.

Harvest and use

Cut the central head while the buds are tight; side shoots follow for weeks. Autumn broccoli is sweeter.

What to watch for

Cabbage worms, aphids in the head, and bolting in heat.
