About

Agave 'Cornelius' is a slow-growing perennial that rarely produces flowers. It forms a rosette of robust leaves featuring sharp teeth along their margins, with a dense cluster of new growth at the center. The foliage displays a blue-green hue complemented by pale yellow edges, creating a distinctive focal point in any landscape.
