Native to South Africa, Encephalartos horridus is an evergreen, slow-growing cycad that makes its home on rocky outcroppings, slopes and ridges in the Eastern Cape Province. It is a dioecious gymnosperm with cylindrical male cones and oval female cones. Fertilization takes place in summer.

If a gardener can find one in the trade, and if he is willing to handle a plant as prickly as this one, the 'Ferocious Blue Cycad' makes a striking container plant in the garden in summer. North of zone 10, however, it must be taken indoors for the winter... and there is the rub... or scratch.

Ice Blue Cycads in San Diego is a possible source for this plant.
