Dioon

Zamiaceae
Palms and cycads

In general, these Mexican and Central American cycads resemble Cycas revoluta and take the same culture. Dioons are more tender, even slower growing, and less frequently sold.

Dioon edule

Very slow growing. Eventually forms a cylindrical trunk 6–10 in. wide, 3 ft. high. Leaves are spreading, slightly arching, 3–5 ft. long; made of many smooth-edged leaflets (sometimes toothed at tips on young plants). Leaves on young plants are dusty blue green, soft, feathery; those of mature plants are shiny, darker green, more rigid.
