Dracaena marginata, more commonly known as a dragon tree, is an attractive plant with green sword-like, red-edged leaves. Native to Madagascar, the eye-catching spiky tree is known as a great entry plant for household gardeners—it's easy to care for, drought-tolerant, and nearly indestructible.

The slow-growing plant can be planted year-round and boasts tiny white flowers in the spring (though it rarely flowers indoors). This small tree will grow to about 20 feet in warm outdoor climates, but 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.

Dracaena marginata do not like temperatures below 65 degrees F.

Trim or prune any yellow leaves and cut the brown spots off leaves with a sharp pair of scissors.
