Weber Agave
Agave weberi
A bold six-foot open rosette with smooth gray-green to blue-green leaves and genuinely sharp terminal tips — a large-space specimen, not a courtyard accent.

AE reviews microclimate, root intrusion risk, and soil compatibility.
Schedule: Very infrequent — often monthly or less once established. None when soil is cool and damp.
Emitters: Single low-flow emitter offset from base, or hand-watering only.
Overwatering is the #1 cause of cactus and agave loss. AE designs cactus zones on their own valve.
Arizona yards have very different microclimates. West-facing walls, glass, artificial turf, pavers, travertine, porcelain, and pool decking all increase reflected heat. AE considers these before confirming placement.

AE verifies pool deck, paver, foundation, wall, and utility clearances before final planting.

About Weber Agave
Weber Agave reads as a clean, modern rosette because the leaf margins are smooth rather than toothed, but the terminal tips are sharp and the plant is large. University of Arizona Cooperative Extension lists it hardy to 15°F, full to partial sun, very low water, moderate growth and a mature size near 6 feet tall and 6 feet wide, with yellow spring-to-summer flowers, and the Extension plant list calls for 5 feet from the property line. Local horticultural guidance describes gray-green to blue-green foliage, a flower stalk that can reach roughly 20 to 26 feet with yellow flower clusters, hardiness in the 10 to 15°F range and susceptibility to the agave snout weevil. It wants well-drained soil, deep irrigation roughly monthly as a practical dry-weather starting point and additional summer water only as conditions require — never continuously wet soil.
Best uses: A six-foot smooth-margined rosette used as a large-space specimen with full mature diameter, setback and maintenance access designed in from the start
AE Designer Opinion
Design Uses
- Large-space specimen in decomposed granite with boulders
- Modern desert entry statement set back from the walk
- Wide front-yard focal point with open sightlines
- Commercial or estate-scale desert planting
- Structural anchor among low desert perennials
Care & Maintenance
- Plant in full to partial sun in well-drained soil
- Water deeply roughly monthly in dry weather as a starting point
- Add summer water only as conditions require and never keep soil wet
- Monitor for agave snout weevil, especially at the base of mature rosettes
- Remove spent lower leaves with tools and eye protection
- Plan for the rosette’s decline after the flower stalk completes
Common Homeowner Mistakes
- Planting it in a tight courtyard or narrow side yard
- Assuming smooth margins mean the plant is safe to brush past
- Setting it too close to a property line or walk
- Running it on a lawn or shrub valve that keeps soil damp
- Ignoring a soft, leaning rosette that signals agave snout weevil
- Trimming leaf tips instead of designing enough clearance
Placement Warnings
⚠ Leaf margins are smooth but the terminal tips are sharp. Keep the full six-foot rosette away from walks, gates, play areas, pet routes, pool circulation and seating, and hold at least the source’s five-foot property-line setback.
- Allow the complete six-foot mature diameter plus maintenance access
- Hold at least the five-foot property-line setback from the Extension list
- Keep sharp terminal tips away from walks, gates and seating
- Keep away from play areas, pet routes and pool circulation
- Allow overhead clearance for a 20–26 ft flower stalk
- Plant in well-drained soil; never leave the root zone continuously wet
