Dioon Spinulosum

Design with this plant

Overview

The Giant Dioon (Dioon spinulosum), a slow-growing cycad, is a focal point for xeriscapes. Mature size reaches up to 15 feet tall, with feathery fronds extending 6 feet. Preferring full sun to partial shade, it thrives in USDA zones 9-11. Once established, it's drought-tolerant, requiring minimal water. Its textured, blue-green leaves add architectural interest. Plant with caution, as its leaves are sharp and it's toxic if ingested.
