The portion used of this plant is the undeveloped flower cluster, or the portion which is known as the scales of the involucre. They are boiled and served with drawn butter, but outside of France do not seem to be very generally appreciated. The plants are propagated first by seeds, sown in a hot-bed in March, and planted out at distances of from two to three feet. It is not always hardy enough for our winters in the northern states, though it proves so in all latitudes south of Washington. Here it is necessary on the approach of winter to draw the leaves together and earth up around them, and later to cover the tops with litter.
