Dioon califanoi - Wikipedia

The Dioon califanoi is one of the most treasured Dioons.  The color when grown in full sun is gray-green, with a slight blue hue.  It is quite ornamental with its keel leaves (shaped like the bottom of a boat).  In your garden it will provide dramatic contrast against your Encephalartos—the leaflets, leaves and caudex are completely different, and it has an enticing color that you will learn to like.  The tips of the leaves are pointy-sharp (termed pungent), similar to the Encephalartos lehmannii.  The distinctive difference that most folks see is the precise, nearly perfect stacking of the stiff leaflets, like a venetian blind. Your visitors will remark how different this cycad is from the others (a conversation starter) and you will inform them that most of the Encephalartos are from South Africa but the Dioon califanoi is from Oaxaca (pronounced Oh-wahkah), Mexico.
