Turnips are a relatively easy and delicious fall crop. According to vegetable-gardening-online.com, turnips are not a popular home crop, probably because they have become known as the “poor man’s vegetable.” The truth is, turnip plants yield tasty bulbs, plus they give gardens some of the first harvest greens. Along with their twin, rutabaga, turnips are indeed inexpensive, but yummy and beautiful all the same.
