This plant is very tall and makes a good screen plant. It resembles giant celosia when in bloom and is indeed related to that popular annual. The flowers can be use in fresh and dried arrangements, but cutting the flowers will reduce your yield.
Young leaves can be steamed and eaten like spinach. The grains can be added to soups and stews, cooked as a hot cereal or side dish, or ground into flour and used in pancakes, muffins and breads. They can even be popped, like corn, for snacking.
