Lemon-lime dracaena is in the asparagus plant family (Asparagaceae), and it’s also commonly referred to as a corn plant, although you won’t harvest asparagus or corn from this plant. Its foliage resembles the leaves of a cornstalk, and it’s in the asparagus plant family simply because of certain genetic similarities. As it grows, lemon-lime dracaena loses its lower leaves until a rosette of corn-like foliage is held atop its cane-like stem.Across its native habitat in Africa, corn plant may grow to a height that exceeds 20 feet, but you can expect it to reach a height of only 4 to 6 feet as a houseplant. Gardeners in U.S. Department of Agriculture plant hardiness zones 10 through 12 can grow lemon-lime dracaena outdoors year-round as a perennial, but gardeners in other zones enjoy it as a houseplant.
