Cruciferous Vegetables Challenge – One Plant, Many Vegetables

Cruciferous vegetables belong to the mustard family, named for their four-petaled, cross-shaped flowers. Remarkably, broccoli, cabbage, kale, cauliflower, Brussels sprouts and kohlrabi are all one species, Brassica oleracea, bred to emphasize different parts.

Breeders selected for leaves in kale, flower buds in broccoli and cauliflower, side buds in Brussels sprouts and swollen stems in kohlrabi. Romanesco broccoli even forms fractal spirals. Overcooking releases sulfur compounds that cause strong smells.

Cabbage is the basis of fermented foods like German sauerkraut and Korean kimchi. Mustard, wasabi, horseradish and radishes are also crucifers. Some people find these vegetables bitter because genes affect how they taste certain compounds.
