Agave sisalanaSisal Agave

Agave sisalana, known as the Sisal Agave, is the fibre agave of the dry tropics, grown for centuries in plantations and now valued as much for its architecture as its rope. Rigid blue-green blades radiate from a tight basal rosette, each ending in a hard terminal spine, and after many years the plant throws a flowering mast several metres tall before dying and leaving offsets behind.

In landscape work it earns its place in gravel gardens, arid medians and hot exposed frontages where irrigation is minimal and a strong sculptural line is wanted.

Specifications

• Height1.5 to 2 metres in leaf, with a flowering mast to 6 metres
• Width2 to 3 metres
• Native toSouthern Mexico; long cultivated across the dry tropics
• FoliageRigid, sword-shaped blue-green succulent leaves in a basal rosette, each tipped with a hard spine; evergreen
• Growth rateModerate

Conditions

• SoilRequires free-draining sandy or gravelly soils; tolerates poor, stony and saline ground
• LightFull sun
• WaterLow; highly drought-tolerant once established
• ClimateThrives in arid, semi-arid and hot subtropical regions

Additional Features

• FormBold symmetrical rosette on a short stem, producing offsets at the base
• UsesIdeal for xeriscape and gravel gardens, arid medians, slope stabilisation and sculptural accent planting
• SpacingPlant 2 to 3 metres apart to allow the rosette to develop fully
• Low MaintenanceNeeds almost no care; remove spent leaves and the flowering mast after seeding
• Pest ResistanceRobust and generally free of pests
• Drought ToleranceSurvives long rainless periods on stored leaf moisture
• Salt ToleranceTolerates saline soils and coastal exposure
• ToxicityLeaf sap can irritate skin and the terminal spines are sharp; keep back from paths and play areas

The Sisal Agave delivers a hard-edged, low-water statement in the kind of hot exposed ground where softer planting will not survive.
