Grouped as a cactus or succulent by the genus Yucca, which is reliably one kind of plant (archetype table). Rain rule: no rainy season to read (98 mm a year); the temperature rule's cooler six months are November to April in the northern hemisphere. Habitat rain 98 mm a year, wettest December at 20 mm, driest May at 1 mm (habitat calendar, northern hemisphere). Open sky over the habitat: 24 to 52 mol/m²/day. Cold floor 7.4 °C (1st-percentile habitat night, NASA POWER).

Each sentence is one card's own one-line form, written by the same rule as the card (Its year, Rain, Light, Temperature); the note cannot say what a card does not. Months are given for the northern hemisphere (set your site in Settings to change this), and the habitat's own alongside. The cards · the figures.

Cultivation

Grouped as a cactus or succulent by the genus Yucca, 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: no rainy season to read (98 mm a year); the temperature rule's cooler six months are November to April in the northern hemisphere.

This species’ habitat figures, and what two fixed rules read from them.

Rain at the habitat is 98 mm a year (median year across the envelope cells, CHELSA). Under 120 mm the rain rule reads no rainy season, and the growing-season rule infers nothing from it. The temperature rule reads the cooler six months as November to April. Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: May to October.

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 98 mm a year, wettest December at 20 mm, driest May at 1 mm (habitat calendar, northern hemisphere).

98 mm a year at the habitat. Wettest month December at 20 mm, driest May at 1 mm; 3 months under 5 mm. Across the envelope cells the year's total runs 80 mm to 200 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: 24 to 52 mol/m²/day.

Open sky over the habitat: 24 to 52 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 23, the highest 90th-percentile month 54).

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 7.4 °C (1st-percentile habitat night, NASA POWER).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is 7.4 °C, the absolute minimum 3.4 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 41.0 °C. Monthly means: coldest night 10.9 °C in January (across the envelope cells 8.3 °C to 14.7 °C), warmest day 32.5 °C in August (median year across the envelope cells, CHELSA). Cold floor: 7.4 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).

Each figure is the median across the 281 grid cells holding the 574 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 1236:1319 (28.175, -114.025). Over 44 years there: absolute minimum 3.4 °C, 1st-percentile night 7.4 °C, 99th-percentile day 41.0 °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 281 distinct grid cells holding the 574 in-range records; extremes and elevation at the typical cell 1236:1319 (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 28.00_-113.750, lapse-corrected -168 m at 6.5 °C/km. Elevation: ETOPO 2022, 12 m (cell mean).

Natural habitat

Native range as published by WCVP; the marker is where the records are densest and decides nothing: the climate was read across every in-range record's cell, not at the marker.
