Agave weberi, Weber's Agave, is a large open rosette of long blue-grey leaves that arch outward and taper to a fine point. Mature leaf margins are almost smooth, unusual in a plant of this size, which gives the whole rosette a softer outline than most big agaves. It builds a broad trunkless mound.
Full sun, free-draining soil and very little else. It grows quickly at 30 to 60 centimetres a year, tolerates salt-laden coastal wind, shrugs off long dry periods and takes light to moderate frost once established. Offsets form around the base and can be lifted and replanted or cut away for a single rosette.
Use it where there is room: coastal frontages, carpark islands, roadside beds, large rockeries and commercial landscapes that have to survive on rainfall. One plant fills a three metre bed on its own, which makes it an efficient way to cover ground in hot, exposed sites with no irrigation.
Frequently Asked Questions
About Weber's Agave
What is Weber's Agave?
Agave weberi is a large evergreen succulent forming an open rosette of long, arching, blue-grey leaves that taper to a fine point. Unusually for an agave of this size the mature leaf margins are almost smooth, so the outline is softer than most. It suckers from the base and is grown as a broad feature plant.
How big does Weber's Agave grow?
A single rosette reaches roughly 1.2 to 1.5 metres high and 2 to 3 metres wide, and clumps spread further as offsets develop. Plan the bed around the width rather than the height. Give it two and a half to three metres of clear ground so the arching leaves are not pushed against paving or walls.
How fast does it grow?
Quickly for an agave, 30 to 60 centimetres a year through the warm months given sun and drainage. Plants reach a useful landscape size within two to three seasons, which is why it is often chosen for jobs that need immediate presence. Growth slows sharply over winter and in cold inland gardens.
Is Weber's Agave suitable for coastal positions?
Yes, it is one of the better succulents for the coast. It handles salt-laden wind, sand and the sharp drainage that comes with it, and is used on foreshore reserves and beachside frontages. Sandy soil suits it as it is. Water through dry spells in the first year while roots extend into the sand.
Is it frost tolerant?
Established plants tolerate light to moderate frost. Young plants and recent transplants are more vulnerable, so plant in spring rather than autumn in cold districts and let them settle before winter. As with all agaves, cold combined with wet soil is the danger, and drainage matters more than the minimum temperature.
Is it drought tolerant?
Highly. Once established it survives on rainfall through long dry periods and is regularly specified for unirrigated sites. Growth is faster with occasional deep watering in summer, so if speed matters, water monthly for the first two years. Beyond that, extra water gives little benefit and can encourage rot in heavy soil.
How do I care for Weber's Agave?
Remove dry lower leaves at the base to keep the rosette clean, and lift or cut away offsets if you want a single specimen rather than a clump. Wear gloves and long sleeves, as the leaf tips are sharp and the sap can irritate skin. No pruning, feeding or spraying is otherwise needed.
