Rain rule: no season, 70% of the rain takes 8 months (January and May to November at the habitat (not shifted)). Habitat rain 2731 mm a year, wettest June at 293 mm, driest March at 159 mm (habitat calendar, northern hemisphere). Open sky over the habitat: 24 to 36 mol/m²/day. Cold floor 22.1 °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

Its year Rain rule: no season, 70% of the rain takes 8 months (January and May to November at the habitat (not shifted)).

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

The rain rule reads no season: 70% of the year's rain (2041 mm of 2731 mm) takes 8 months, January and May to November. Mean temperature moves 3.6 °C between the warmest and coldest month. Months are the habitat's, northern hemisphere; with a flat temperature curve there is no season to reverse, so they are not shifted for a collection elsewhere.

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.

2731 mm a year at the habitat, 2041 mm of it January and May to November. Wettest month June at 293 mm, driest March at 159 mm. Across the envelope cells the year's total runs 1593 mm to 4084 mm (10th to 90th percentile of each cell's own year) (median year across the envelope cells, CHELSA; habitat calendar, northern hemisphere).

Light Open sky over the habitat: 24 to 36 mol/m²/day.

This species’ habitat figures, with their source.

Open sky over the habitat: 24 to 36 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 18, the highest 90th-percentile month 41).

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.

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is 22.1 °C, the absolute minimum 20.5 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 29.4 °C. Monthly means: coldest night 21.9 °C in January (across the envelope cells 13.3 °C to 25.0 °C), warmest day 28.1 °C in June (median year across the envelope cells, CHELSA). Cold floor: 22.1 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).

Each figure is the median across the 37 grid cells holding the 46 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 1788:6152 (0.575, 127.625). Over 44 years there: absolute minimum 20.5 °C, 1st-percentile night 22.1 °C, 99th-percentile day 29.4 °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 37 distinct grid cells holding the 46 in-range records; extremes and elevation at the typical cell 1788:6152 (its coldest month's mean night nearest the median across cells); its position is the cell centre.
