7. What is the best Brassica? I collect here the most common for readers negligent in their Brassica studies:

   species	examples

   oleracea	kale, cabbage, collard greens, broccoli, cauliflower, Chinese broccoli, Brussels sprouts, turnip cabbage
   rapa	bok choy, choy sum, napa cabbage, turnip, canola (sometimes)
   carinata	Ethiopian rape, Ethiopian mustard
   napus	rutabaga, rapeseed, turnip (sometimes), canola (often)
   juncea	mustard greens, Chinese/Indian/Korean mustard, canola (sometimes)
