Dragon tree (Dracaena marginata), is a tall plant with green, sword-like, red-edged leaves. Native to Madagascar, the eye-catching spiky tree is a great entry plant for household gardeners wanting an indoor tree—it's easy to care for, drought-tolerant, and nearly indestructible. This slow-growing tree can take a decade to reach a few feet tall but can eventually grow to about 20 feet. However, it is generally grown as a potted houseplant and kept pruned to 6 feet or less.
Keep the dragon tree away from pets because it's toxic to animals if ingested
