Carnegiea gigantea

Saguaro is an exotic evergreen perennial tree with a tall, columnar habit. It produces white flowers and maintains its foliage year-round. Commonly used in arid landscape designs, it is suited to large-scale plantings and desert-themed gardens. Its size and form make it suitable as a feature plant or for habitat creation in dry environments. Grows to approx. 10–25m H x 2–4m W.
