Euell Gibbons, in his book "Stalking the Healthful Herbs," says that 100 grams of winter cress contain an impressive 5,067 I.U. of vitamin A and 152 milligrams of vitamin C. By comparison, oranges, known as a good source of vitamin C, provide a comparatively measly 50 milligrams of C per 100 grams.
The two photos, the creasy greens, above, and
the plants to the right below, were taken by me.
You can see the creasy greens also
in the slideshow below, in a wooden crate.
The slideshow photos were taken by Jim.
