Summary
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.

About the genus · Agave
Agave is a genus of monocots native to the arid regions of the Americas. The genus is primarily known for its succulent and xerophytic species that typically form large rosettes of strong, fleshy leaves.

Cultivation
Grouped as a cactus or succulent by the genus Agave, which is reliably one kind of plant (archetype table). The table holds no figure for this group, which spans too much for one minimum; the cold floor is the habitat's alone, and no prose comes from the table.
Its year Rain rule: a summer growing season, May to September in the northern hemisphere (May to September at the habitat, northern).
This species’ habitat figures, and what two fixed rules read from them.
The rain rule reads a summer growing season: 70% of the year's rain (330 mm of 446 mm) falls in May to September, warmer than the year (wet-season mean 19.9 °C against a yearly mean of 17.4 °C). Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: November to March.
Read from the median year of CHELSA monthly rainfall and mean temperature across the envelope cells: the rain rule takes the smallest set of months carrying 70% of the rain and calls it winter when its mean is more than half a degree below the year's, summer when more than that above, and neither in between; the temperature rule, used only under 120 mm, names the cooler six months when they are at least a degree cooler than the other six. Months are shifted for the other hemisphere only where the temperature curve gives a season to reverse. A reading of the curves, not an observation of the plant.
Rain Habitat rain 446 mm a year, wettest July at 79 mm, driest March at 8 mm (habitat calendar, northern hemisphere).
This species’ habitat figures, with their source.
446 mm a year at the habitat, 330 mm of it May to September. Wettest month July at 79 mm, driest March at 8 mm. Across the envelope cells the year's total runs 366 mm to 587 mm (10th to 90th percentile of each cell's own year) (median year across the envelope cells, CHELSA; habitat calendar, northern hemisphere).
CHELSA monthly precipitation, median year across the envelope cells. The rain that falls where the species is recorded; nothing about how the plant takes water.
Light Open sky over the habitat: 28 to 47 mol/m²/day.
This species’ habitat figures, with their source.
Open sky over the habitat: 28 to 47 mol/m²/day across the year (daily light integral, median year across the envelope cells, CHELSA; the lowest 10th-percentile month across the cells is 25, the highest 90th-percentile month 50).
CHELSA shortwave radiation at each envelope cell, a daily-mean flux taken to a daily total and converted at 2.07 mol of PAR per MJ. The sky over the habitat, measured; what reaches a plant under a rock, a shrub or a shade cloth is not.
Warmth and air Cold floor 1.6 °C (1st-percentile habitat night, NASA POWER).
This species’ habitat figures, with their source.
Coldest: the 1st-percentile night over 44 years at the typical cell is 1.6 °C, the absolute minimum -3.8 °C, about 1 frost night a year (NASA POWER daily minima). Warmest: the 99th-percentile day is 34.4 °C. Monthly means: coldest night 6.5 °C in January (across the envelope cells 4.6 °C to 8.1 °C), warmest day 27.7 °C in May (median year across the envelope cells, CHELSA). Cold floor: 1.6 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).
NASA POWER daily minima and maxima 1981–2024 at the typical cell, lapse-corrected to its elevation; CHELSA monthly means, median year across the envelope cells, CHELSA. The cold floor is the figure named in its sentence. Not a measured survival limit for any plant in a pot.
Relative humidity at the habitat: 49 to 63% across the year (monthly means, median year across the envelope cells, CHELSA). A figure about the air, saying nothing about how the plant takes water.

Each figure is the median across the 23 grid cells holding the 24 in-range records, with the 10th–90th percentile span across those cells after the slash where it differs. Extremes and elevation were read at the typical cell 1365:1579 (21.725, -101.025). Over 44 years there: absolute minimum -3.8 °C, 1st-percentile night 1.6 °C, 99th-percentile day 34.4 °C. Normals: CHELSA V2.1 1981–2010 climatology, 0.05° cells (each the mean of ~36 1 km pixels). Envelope: median and 10th–90th percentile of each month across the 23 distinct grid cells holding the 24 in-range records; extremes and elevation at the typical cell 1365:1579 (its coldest month's mean night nearest the median across cells); its position is the cell centre. Extremes: NASA POWER (MERRA-2) daily 1981–2024, cell 21.50_-101.250, lapse-corrected -358 m at 6.5 °C/km. Elevation: ETOPO 2022, 1855 m (cell mean).
