Brussels sprout plants are members of the cruciferous vegetable family, and are related to cabbage, cauliflower, and broccoli. They are a cool-season crop, and are typically grown in the spring or fall. Brussels sprout plants produce small, green heads that resemble miniature cabbages. The heads are typically harvested when they are about 1 to 2 inches in diameter. The plants grow to a height of about 2 to 3 feet, and have a spreading habit with many stems. The leaves are dark green and have a waxy texture.
