Agave univittata, the thorn-crested century plant or thorn-crested agave, is a plant species native to coastal areas of southern Texas and northeastern Mexico, at elevations less than 100 m (300 feet). It has been widely named Agave lophantha by botanists including Howard Scott Gentry, but the name A. univittata is older and therefore more in accord with nomenclatural rules of botany. It is cultivated as an ornamental plant, and in the UK the cultivar 'Quadricolor' has won the Royal Horticultural Society's Award of Garden Merit.
