Wikipedia tells us that Mangelwurzel or mangold wurzel (from German Mangel/Mangold, "chard", and Wurzel, "root"), also called mangold, mangel beet, field beet and fodder beet, is a cultivated root vegetable derived from Beta vulgaris. Its large white, yellow or orange-yellow swollen roots were developed in the 18th century as a fodder crop for feeding livestock
Apparently Brits used to eat "Mangowuzels" during the war and that left an upalatable dislike for this root vegetable! Not having experience that, I personally love root vegs, and they still looks good enough to paint.
