More about this plant
Agave weberi, known as maguey liso in Spanish and as Weber's agave in English, is a succulent perennial plant in the family Asparagaceae, subfamily Agavoideae. Under the synonym Agave neglecta, it is known as wild century plant and Small's agave—the latter in honor of its discoverer in Florida, John Kunkel Small. Naturalized populations in Florida were considered to be a separate species but are now treated as synonymous with A. weberi. Wikipedia →

How we know this (2) Methods & honest limits
A recorded categorical fact: each species is tagged C3 (standard), C4 (heat/water-efficient) or CAM (succulent, night-time CO₂ uptake) — or a facultative combination. We only show a trait card for the noteworthy C4/CAM cases; C3 is the unremarkable majority, kept in the data but not surfaced as a card.
We take the plant’s U.S. county range and look up each county’s long-term climate, then summarise: native rainfall = the median annual rainfall across its counties; heat tolerance = the warm end (90th percentile) of average temperature across its range (mirroring how our cold-hardiness floor uses an extreme). Counties + medians blunt the roadside/observer bias that makes point-level climate unreliable. Needs at least five placeable counties.
Honest limits: A realized, sampling-biased niche (where it has been recorded, not its physiological optimum), and county climate is coarse — large Western counties span deserts and mountains. Derived guide, never a measured fact.
