Compared to other beans, adzuki beans have a slightly sweet flavor. The plant grows 1 to 2 feet high with leaves resembling those of Southern peas. The plant yields yellow flowers that are followed by a cluster of smooth, short, cylindrical pods containing seeds two to three times larger than mung beans. The seeds are primarily dark red, but can include green, straw-colored, black-orange, and mottled seeds. The seeds are round with a protruding ridge (seed scar) on the side.
