Dioon spinulosum

Giant Dioon is one of the tallest cycads in the world and produces one of the largest, if not the largest, cones of any living plant. It is endemic to limestone cliffs and rocky hillsides in the tropical rainforests of Veracruz and Oaxaca, Mexico. Elegant and palm-like, Dioon spinulosum has blue-green pinnate fronds that form a perfectly arranged rosette and arch gracefully. The narrow leaflets are armed with small teeth along their edges. Slow growing, up to 4 to 12 feet tall and wide. Grow in moist, gritty, well-drained soil in full sun to part shade. Drought tolerant once established. Spectacular as a specimen plant. (Pot size: 3 gallon)
