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

Its year Rain rule: no season, 70% of the rain takes 8 months (March to July and September to November in the northern hemisphere).

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

The rain rule reads no season: 70% of the year's rain (664 mm of 881 mm) takes 8 months, March to July and September to November. Mean temperature moves 18.8 °C between the warmest and coldest month. Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: September to January and March to May.

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.

881 mm a year at the habitat, 664 mm of it March to July and September to November. Wettest month June at 111 mm, driest January at 51 mm. Across the envelope cells the year's total runs 583 mm to 1089 mm (10th to 90th percentile of each cell's own year) (median year across the envelope cells, CHELSA; habitat calendar, northern hemisphere).

Open sky over the habitat: 17 to 43 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 17, the highest 90th-percentile month 44).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is -4.5 °C, the absolute minimum -16.1 °C, about 20 frost nights a year (NASA POWER daily minima). Warmest: the 99th-percentile day is 41.2 °C. Monthly means: coldest night 6.1 °C in January (across the envelope cells 3.5 °C to 8.4 °C), warmest day 34.2 °C in August (median year across the envelope cells, CHELSA). Cold floor: -4.5 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).

Each figure is the median across the 459 grid cells holding the 1263 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 1193:1644 (30.325, -97.775). Over 44 years there: absolute minimum -16.1 °C, 1st-percentile night -4.5 °C, 99th-percentile day 41.2 °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 459 distinct grid cells holding the 1263 in-range records; extremes and elevation at the typical cell 1193:1644 (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 30.50_-97.500, lapse-corrected +11 m at 6.5 °C/km. Elevation: ETOPO 2022, 195 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.

Openly licensed records inside the range, framed on where they fall.
