Agave americana “Deep Blue”

Agave americana is an old standard and has been in gardens for centuries all around the globe in Mediterranean climates. Agave americana “Deep Blue” is admired for its rich blue color. It is one of the larger Agaves and reaches dimensions of over 10′ in diameter. Not suitable near driveways or walkways as leaves are sharp and stiff. Best when made a focal piece to be seen from afar. Very drought tolerant. The name ‘Century Plant’ is misleading as the plant really lives about 7-10 years before flowering. It will stay small as long as it is restrained in a container. In the garden, it needs to be maintained by removing offsets or it will mug the gardener.

Leaves have recurved spines on their margins and a long terminal spine. Care must be taken to locate this plant away from foot traffic. When a plant blooms, it sends up a single erect flower stalk from the center of the leave rosette which can reach 40 feet in height. The flower stalk resembles a narrow telephone pole with horizontal branches that hold the flowers spreading out at the top. 3-4 inch greenish-yellow flowers bloom sequentially in panicles at the branch ends. The plant is deer resistant. Its sap can irritate skin – so do not trim with a chainsaw. Agave americana grows faster in summer with some additional irrigation.
