Taxonomy edit
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 edit
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]
