Brassica /ˈbɹæs.ɪ.kə/

Common name: Kale · Cabbage · Broccoli · Cauliflower · Brussels sprouts · Kohlrabi

Brassica A genus of about 40 species in the mustard family, native to Europe, the Mediterranean, and temperate Asia, and central to world agriculture. Through centuries of selection, Brassica oleracea alone has yielded cabbage, kale, broccoli, cauliflower, Brussels sprouts, and kohlrabi from a single wild coastal ancestor. These are cool-season crops that like full sun, fertile soil, and steady moisture, and many also serve as striking ornamental kales in autumn beds and containers.

Care summary

Water Evenly moist soil; consistent watering

Fun facts

  • Kale, cabbage, broccoli, cauliflower, Brussels sprouts, kohlrabi, and collard greens are all one species.
  • Each crop was bred for a different plant part — leaves, buds, flowers, stems, or side shoots.
  • Kale's flavor actually improves after a light frost, which converts starches into sugars.
