"Brassica oleracea is a plant species from family Brassicaceae that includes many common cultivars used as vegetables, such as cabbage, broccoli, cauliflower, kale, Brussels sprouts, collard greens, Savoy cabbage, kohlrabi, and gai lan."
Sure is ... and those varieties seem to grow very well where we cut down all the Redwoods. Coincidence?
I've never punched a brassica, but I have embedded my hand in the downy soft bark which sits on a sequoia trunk.
