A modest-sized agave with a dynamically symmetrical shape and growth habit makes Agave horrida an excellent choice for many landscape uses. Mexcalmetl Agave leaves are dagger-shaped with many sharp, evenly spaced, light-gray marginal teeth and are typically dark green. This agave grows well in full sun but tolerates some filtered shade locations without a problem. It is a tough and attractive agave that should be planted in well-drained soil and watered occasionally to keep it looking the best.
