Grouped as a cactus or succulent by the genus Yucca, which is reliably one kind of plant (archetype table). Rain rule: a summer growing season, June to September in the northern hemisphere (June to September at the habitat, northern). Habitat rain 682 mm a year, wettest June at 140 mm, driest December at 7 mm (habitat calendar, northern hemisphere). Open sky over the habitat: 31 to 46 mol/m²/day. Cold floor 1.9 °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: a summer growing season, June to September in the northern hemisphere (June 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 (482 mm of 682 mm) falls in June to September, warmer than the year (wet-season mean 18.2 °C against a yearly mean of 17.1 °C). Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: December 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 682 mm a year, wettest June at 140 mm, driest December at 7 mm (habitat calendar, northern hemisphere).

This species’ habitat figures, with their source.

682 mm a year at the habitat, 482 mm of it June to September. Wettest month June at 140 mm, driest December at 7 mm. Across the envelope cells the year's total runs 558 mm to 871 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: 31 to 46 mol/m²/day.

This species’ habitat figures, with their source.

Open sky over the habitat: 31 to 46 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 28, the highest 90th-percentile month 47).

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 1.9 °C (1st-percentile habitat night, NASA POWER).

This species’ habitat figures, with their source.

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is 1.9 °C, the absolute minimum -6.1 °C, about 1 frost night a year (NASA POWER daily minima). Warmest: the 99th-percentile day is 32.6 °C. Monthly means: coldest night 7.6 °C in January (across the envelope cells 5.2 °C to 10.7 °C), warmest day 26.1 °C in April (median year across the envelope cells, CHELSA). Cold floor: 1.9 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).

Each figure is the median across the 117 grid cells holding the 291 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 1436:1651 (18.175, -97.425). Over 44 years there: absolute minimum -6.1 °C, 1st-percentile night 1.9 °C, 99th-percentile day 32.6 °C.

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.
