Seven Top Turnip Greens

Today's painting is of turnips greens, in particular a variety called Seven Top sold by Southern Exposure, of course:

As the SESE catalog tells me, these turnips are grown only for their greens as their roots are woody, but the greens are totally worth it because they are so good for you. An article from the New York Times tells me that in order to get the same amount of calcium from cooked turnip greens as you would an 8oz glass of milk you only need to eat 7.5 oz, (see the calcium equivalent chart here: http://health.nytimes.com/health/guides/nutrition/calcium-in-diet/overview.html). They also have a whole bunch of other good vitamins and nutrients in them. You can see a nutrient chart and read up more about them here: http://www.whfoods.com/genpage.php?tname=foodspice&dbid=144
And it turns out turnip greens can make you sing. Here is a site with a list of ten songs, mostly country, mentioning these famous veggies: http://www.funtrivia.com/en/subtopics/Turnip-Greens-in-Song-259990.html
