Dracaena serrulata

Also called 'Yemen Dragon Tree' or 'Arabian Dragon Tree'. Its name D. serrulata refers to the edges of its serrated leaves and differs from other Dracaena by its stiff, very narrow blue-green leaves. It is found in northern Yemen and Oman. It grows on rocky slopes in well-drained soil with little water and lots of sun. The stem can grow up to 35 centimeters in diameter or more. On average, small trees grow up to three or five meters, but under the right conditions it could reach even twelve meters.
