Summary

Dasylirion leiophyllum is a species of flowering plant in the asparagus family known by the common names green sotol, smooth-leaf sotol, and smooth sotol. It is native to North America, where it occurs in Chihuahua and Coahuila in Mexico and New Mexico and western Texas in the United States. It was first collected by Valery Havard in 1880 and was described by William Trelease in 1911.

About the genus · Dasylirion

Dasylirion is a genus of succulent, rosette-forming plants in the Asparagaceae family, where it is included in the subfamily Convallarioideae. Most species are native to mountainous arid regions of Mexico, with some species also native to the Southwestern United States. The common name sotol is used in English and Spanish to describe various Dasylirion species, as well as giving its name to a distilled spirit made from some species of the genus.

Rain rule: a summer growing season, May to October in the northern hemisphere (May to October at the habitat, northern). Habitat rain 377 mm a year, wettest July at 64 mm, driest March at 11 mm (habitat calendar, northern hemisphere). Open sky over the habitat: 23 to 49 mol/m²/day. Cold floor -5.5 °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.

Also known as Dasylirion heteracanthium I.M.Johnst.; Dasylirion heteracanthum I.M.Johnst.; Dasylirion leiophyllum var. heteracanthum (I.M.Johnst.) Bogler; Dasylirion stewartii I.M.Johnst.; Dasylirion stewartii var. glaucum I.M.Johnst.

Cultivation

Its year Rain rule: a summer growing season, May to October in the northern hemisphere (May to October 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 (294 mm of 377 mm) falls in May to October, warmer than the year (wet-season mean 23.3 °C against a yearly mean of 17.3 °C). Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: November to April.

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 377 mm a year, wettest July at 64 mm, driest March at 11 mm (habitat calendar, northern hemisphere).

377 mm a year at the habitat, 294 mm of it May to October. Wettest month July at 64 mm, driest March at 11 mm. Across the envelope cells the year's total runs 282 mm to 469 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: 23 to 49 mol/m²/day.

Open sky over the habitat: 23 to 49 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 21, the highest 90th-percentile month 51).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is -5.5 °C, the absolute minimum -14.6 °C, about 51 frost nights a year (NASA POWER daily minima). Warmest: the 99th-percentile day is 39.4 °C. Monthly means: coldest night 1.7 °C in January (across the envelope cells -0.3 °C to 4.8 °C), warmest day 32.8 °C in June (median year across the envelope cells, CHELSA). Cold floor: -5.5 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).

Climate across the habitat

Habitat climate through the yearMean day from 15 °C in Jan to 33 °C in Jun; mean night from 2 °C in Jan to 20 °C in Jul. The cold quarter, Dec to Feb, is the three months around the coldest night. 377 mm of rain a year, most in Jul. The bands show the 10th to 90th percentile across 226 habitat cells. Over 44 years at the typical cell the absolute minimum was -14.6 °C and the 99th-percentile day 39.4 °C; neither is dated to a month.

Each figure is the median across the 226 grid cells holding the 610 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 1169:1483 (31.525, -105.825). Over 44 years there: absolute minimum -14.6 °C, 1st-percentile night -5.5 °C, 99th-percentile day 39.4 °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 226 distinct grid cells holding the 610 in-range records; extremes and elevation at the typical cell 1169:1483 (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 31.50_-105.625, lapse-corrected -21 m at 6.5 °C/km. Elevation: ETOPO 2022, 1322 m (cell mean).
