Dioon spinulosum, also known as the Giant Dioon, is a slow-growing cycad native to Mexico. Over time, it can reach impressive heights of more than 10 metres. This plant features a striking crown of stiff, light green fronds with pointed tips, giving it a lush and tropical appearance. Adapted to thrive in poor, rocky soils on limestone slopes, Dioon spinulosum is remarkably hardy and low-maintenance.
It prefers positions in full sun or partial shade and requires well-drained soil. Both drought and frost tolerant, this cycad is ideal for gardens seeking a dramatic, easy-care focal point.
