Ferocactus glaucescens, the glaucous barrel cactus, is a species of flowering plant in the family Cactaceae, native endemic to México.

Description

Ferocactus glaucescens is a solitary or branching cactus with spherical or cylindrical blue-green frosted shoots, growing up to 45 centimeters in height and 60 cm (24 in) in diameter. The shoots have slightly depressed apices and 12 to 17 sharp-edged, non-tuberculated ribs with elongated areoles that are often connected. Its yellow spines, which are difficult to distinguish between central and peripheral, can reach up to 3.5 centimeters in length, with one central spine and 6 to 7 radial spines.

The bell-shaped, yellow flowers of Ferocactus glaucescens are up to 4.5 centimeters long and 2.5 to 3.5 centimeters in diameter. Its spherical, whitish or yellowish, red-tinged fruits are fleshy, reaching lengths of up to 2.5 centimeters and covered in yellowish, ciliated scales.[2][3]

Taxonomy

First described as Echinocactus glaucescens in 1828 by Augustin Pyramus de Candolle, the specific epithet "glaucescens" comes from the Latin words "glaucus" for 'blue-green' and "-escens" for 'becoming', referring to the color of the shoots.[4] In 1922, Nathaniel Lord Britton and Joseph Nelson Rose reclassified it into the genus Ferocactus.

Cultivation

In cultivation in temperate regions it must be grown under glass. It has gained the Royal Horticultural Society's Award of Garden Merit.[5][6] There is a spineless form, Ferocactus glaucescens forma nuda (inermis).[7]
