Rain rule: no season, 70% of the rain takes 8 months (October to May in the northern hemisphere). Habitat rain 809 mm a year, wettest June at 83 mm, driest February at 45 mm (habitat calendar, southern hemisphere). Open sky over the habitat: 12 to 45 mol/m²/day. Cold floor 7.8 °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 (October to May 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 (589 mm of 809 mm) takes 8 months, April to November. Mean temperature moves 7.7 °C between the warmest and coldest month. Months are the habitat's, southern hemisphere; shifted six months for a northern-hemisphere collection: October 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.

Rain Habitat rain 809 mm a year, wettest June at 83 mm, driest February at 45 mm (habitat calendar, southern hemisphere).

809 mm a year at the habitat, 589 mm of it April to November. Wettest month June at 83 mm, driest February at 45 mm. Across the envelope cells the year's total runs 616 mm to 1184 mm (10th to 90th percentile of each cell's own year) (median year across the envelope cells, CHELSA; habitat calendar, southern hemisphere).

Light Open sky over the habitat: 12 to 45 mol/m²/day.

Open sky over the habitat: 12 to 45 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 9, the highest 90th-percentile month 47).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is 7.8 °C, the absolute minimum 5.5 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 29.2 °C. Monthly means: coldest night 8.8 °C in July (across the envelope cells 5.6 °C to 10.8 °C), warmest day 21.3 °C in February (median year across the envelope cells, CHELSA). Cold floor: 7.8 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).

Each figure is the median across the 605 grid cells holding the 1510 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 2569:6503 (-38.475, 145.175). Over 44 years there: absolute minimum 5.5 °C, 1st-percentile night 7.8 °C, 99th-percentile day 29.2 °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 605 distinct grid cells holding the 1510 in-range records; extremes and elevation at the typical cell 2569:6503 (its coldest month's mean night nearest the median across cells); its position is the cell centre.
