Family

Botanical Name

BRASSICA oleracea 'Bubbles'( Gemmifera Group)

Plant Common Name

Brussels Sprouts, Bubbles Brussels Sprouts

General Description

If you love Brussels sprouts but live where high heat and humidity are common, you should try 'Bubbles.' It is an outstanding, easy-to-grow, heat-tolerant variety that is also resistant to powdery mildew and drought. It forms strong, upright, knee-high stems lined with fleshy, cabbage-like leaves. In 88 to 90 days after planting, Brussels sprouts are mature and ready to harvest from along the stems.

The Brussels sprout is a cool season vegetable first cultivated in late medieval or renaissance times in what is now Belgium. It 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.

Brussels sprout plants have strong upright central 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 "buds" 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. Days to harvest vary from cultivar to cultivar but most mature in 80 to 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.
