How an Unappetizing Shrub Became Dozens of Different Vegetables
15th March 2026
Every crop we consume came from a wild ancestor. Through breeding, people selected for bigger grains, juicier fruit, more branches, or shorter stems – gradually turning wild plants into improved yet recognizable versions of their originals. The rare exception is Brassica oleracea, wild cabbage: the origin of cabbage, bok choy, collard greens, broccoli, Brussels sprouts, cauliflower, and much else.
Wild cabbage is unassuming: some untidy leaves and a few thick, coarse stems on the browner side of purple that poke out from the soil. Nothing about it looks appetizing.
Nothing about any of its cultivars looks appetizing, either.
