Agave ‘Blue Glow’

It forms a tight, symmetrical rosette of smooth, blue-gray leaves edged with a luminous golden-orange margin. Each leaf tapers to a firm terminal spine, giving the plant its signature form. The leaves are blue and gray, consistent in color among succulents.

Century Plant Agave is monocarpic, meaning it blooms once after many years of growth, sending up a tall flower spike with yellow blossoms before completing its life cycle. Blooming is triggered in part by a significant night temperature drop, so plants grown indoors may rarely flower without that seasonal cue.

Century Plant Agave can go up to ten days without water and tolerates dry heated air with ease. You can move it outside for summer, where it handles balcony wind without trouble, and it can stay outdoors well into autumn in mild climates. The firm leaf tips and sap can cause skin and paw irritation, so keep it on a high shelf out of reach of both pets and small children.

Water it deeply every 2-3 weeks in summer, reducing to once a month or less in winter.

Century Plant Agave does best in a fast-draining cactus and succulent mix amended with extra perlite or coarse grit.

It prefers temperatures between 50-90F and tolerates brief dips to around 25F with protection from prolonged frost.

Century Plant Agave is a slow to moderate grower that needs only a light balanced fertilizer once in spring and once in early summer.

It is hardy in USDA Zones 9-11, tolerating brief cold down to around 25F before needing frost protection. It grows outdoors year-round across California, Texas, Arizona, Florida, Hawaii, Nevada, New Mexico, Louisiana, Georgia, South Carolina, Alabama, and Mississippi, as well as along the Oregon and Washington coasts. In Zone 9 areas including parts of Arkansas, Tennessee, and central Texas, winter shelter helps keep it looking its best.
