Dioon argenteum 12cm CAUDEX

Dioon argenteum is one of the rarest and most spectacular cycads in the world — endemic to the Sierra Madre del Sur of Oaxaca in southern Mexico, where it grows on steep, rocky limestone slopes in seasonally dry tropical forest. This specimen has a 12 cm caudex, a size that reflects years of the extremely slow growth typical of the Dioon genus. The name argenteum means 'silvery' and perfectly describes the most extraordinary ornamental character of the species: stiff, pinnate fronds of an intense, brilliant silver-grey — a colour unmatched among cycads in cultivation. Considered Critically Endangered (CR) on the IUCN Red List. Family Cycadaceae.

A specimen of exceptional collector and ornamental value. Requires full sun, very sharp drainage and a dry-to-moderate watering regime, replicating the conditions of the sun-exposed limestone slopes of its native habitat. Moderate cold tolerance compared to other tropical Dioon species.

• Brilliant silver-grey fronds — among the rarest and most spectacular colours in the entire order Cycadales
• 12 cm caudex — a mature specimen of an extremely slow-growing species
• Endemic to Oaxaca, Mexico — Critically Endangered IUCN; wild population in serious decline
• Full sun; very sharp drainage; dry-to-moderate watering
• High-value collector's specimen; rarely available at this size on the international market

Dioon argenteum with a 12 cm caudex is an exceptional specimen of one of the most beautiful and threatened cycads in the world — the silver frond crown, Oaxacan provenance and critical conservation status make it a first-class collector's piece, extremely difficult to find at this size.
