What is Spanish Bayonet Yucca?

Also known as aloe yucca and dagger yucca, Spanish bayonet (Yucca aloifolia) is a hardy yucca plant that grows in zones 8-12. As the common name implies, Spanish bayonet yucca has very sharp, dagger-like foliage. These 12- to 30-inch (30-76 cm.) long and 1- to 2-inch (2.5-5 cm.) wide blades are so sharp that they can cut through clothing and pierce skin beneath.


Because of this, Spanish bayonet is often used in placed beneath windows around the home or as a living security fence. While you can use this sharp plant to your advantage, growing Spanish bayonet yucca near walkways or other areas frequently travelled by people and pets, especially young children, is not recommended.


Spanish bayonet yucca grows 15 feet (4.5 m.) in height. It has a clump-forming habit, so plant width will vary depending on how many offshoots are allowed to grow. As plants mature, they may become top heavy and flop over. Allowing the plant to grow in clumps helps provide support to larger stems. Spanish bayonet yucca plants are available with variegated foliage in some areas.
