About Chestnut dioon
Dioon edule, commonly known as Chamal, is a slow-growing, prehistoric cycad native to Mexico, bringing sculptural elegance to any landscape. Its stiff, blue-green pinnate leaves emerge from a robust trunk, creating a miniature palm-like appearance. It's ideal for xeriscape gardens, sunny patios, or as an accent plant in large containers, where its architectural form can be fully appreciated.
Native range
Mexico (especially in the states of San Luis Potosí, Querétaro, Hidalgo, and Veracruz)
Care tips
It requires full sun to bright partial shade for optimal growth, though it tolerates some shade. Watering should be moderate, allowing the substrate to dry out completely between waterings, as it is very susceptible to root rot from overwatering. Use a well-draining, sandy substrate with good aeration. A common mistake is overwatering, which can be fatal for this species.

- What kills it
