Plant Common Name

Brussels Sprouts

General Description

If you love Brussels sprouts then you will really enjoy growing 'Diablo.' It is an outstanding variety of this cool season vegetable that was first cultivated in late medieval or renaissance times in what is now Belgium. The Brussels sprout was brought to the United States in the mid nineteenth century and began to be heavily cultivated there in the mid twentieth century. Typically grown as an annual, it traces its ancestry to Brassica oleracea, a fleshy-leaved, short-lived perennial from coastal areas of western and southern Europe.

A heavy-bearing, flavorful, disease-resistant selection, 'Diablo' forms strong upright thigh-high stems lined with long-stalked fleshy cabbage-like leaves. Tight rosettes of leaves resembling miniature cabbages develop in the leaf axils, maturing from the base of the plant upwards. Similar to cabbage in flavor, these "sprouts" do not fully develop until late in the season, and become most delectable after light frost. Hot weather causes flaccid, loose, bitter-tasting buds. Although cool weather enhances flavor, plants may flower (or "bolt") following extended chilly spells.

This cool weather crop prefers full sun and fertile, organic-rich garden soil with ample drainage. In areas with short growing seasons it is sown in early spring, but in regions with long hot summers it is best planted in summer for winter harvest. It makes a good winter crop for mild climates. Time from sowing to harvest is approximately 110 days. As with all members of Brassica oleracea, it is susceptible to a number of pests, including cabbage loopers and several other types of caterpillars.
