Summary

Cultivation

Seasons

The rain rule reads no short rainy season: 70% of the median year's rain (808 mm of 1,119 mm) takes 8 months, May to December. Mean temperature moves 28.1 °C between the warmest and coldest month. Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: November to June.

Rain

1,119 mm in the median year at the habitat, 808 mm of it May to December. Wettest month June at 109 mm, driest month February at 69 mm. Across the grid cells of the range the year's total runs 811 mm to 1,418 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 1,118 mm, is the year's rain at the top of the page; the 1,119 mm here is the median year's, the twelve monthly medians added, which the rain rule reads. Habitat calendar, northern hemisphere; median year across the grid cells of the range, CHELSA.

Light

Open sky over the habitat: 8 to 39 mol/m²/day across the year (daily light integral, median year across the grid cells of the range, CHELSA; the lowest 10th-percentile month across the cells is 7, the highest 90th-percentile month 41).

Warmth and air
Temperature

Coldest: the 1st-percentile night over 44 years at a typical spot in the range is -23.0 °C, the absolute minimum -35.5 °C, 6,640 frost nights in 44 years, 150.9 a year (NASA POWER daily minima). Warmest: the 99th-percentile day is 30.1 °C. Monthly means: the coldest month's mean nightly low -12.2 °C in January (across the grid cells of the range -16.0 °C to -7.1 °C), the warmest month's mean daily high 24.8 °C in July (median year across the grid cells of the range, CHELSA). Cold floor: -23.0 °C, which is the 1st-percentile night over 44 years at a typical spot in the range (NASA POWER).

Humidity

Relative humidity at the habitat: 56 to 63% across the year (monthly means, median year across the grid cells of the range, CHELSA). A figure about the air, saying nothing about how the plant takes water.

How this section is made

Each card states this species' habitat figures with their sources, and what two fixed rules read from them; nothing here says what the plant does, wants or tolerates. The rules · the terms.

Seasons. Read from the median year of CHELSA monthly rainfall and mean temperature across the grid cells of the range: 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 moves 4 °C or more and the habitat lies 10° or more from the equator. A reading of the curves, not an observation of the plant.

Rain. CHELSA monthly precipitation, median year across the grid cells of the range. The rain that falls where the species is recorded; nothing about how the plant takes water.

Light. 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. NASA POWER daily minima and maxima over 44 years at a typical spot in the range, lapse-corrected -220 m to its elevation; CHELSA monthly means, median year across the grid cells of the range. The cold floor is the 1st-percentile night named in its sentence. Not a measured survival limit for any plant in a pot.

Humidity. CHELSA relative humidity, median year across the grid cells of the range.

How this section is made
Each figure is the median across the 1370 grid cells on land that hold in-range records (1606 records in those cells; 1 more cell holds records but no land by the elevation layer, so those records sit at sea and the cell is left out), with the 10th–90th percentile span across those cells after the slash where it differs. A dash is a month one or more of those cells has no figure for in the grid (a variable CHELSA does not carry there), so no median is taken rather than one over fewer cells. Extremes and elevation were read at a typical spot in the range, cell 929:2152 (43.525, -72.375). Over 44 years there: absolute minimum -35.5 °C, 1st-percentile night -23.0 °C, 99th-percentile day 30.1 °C. Normals: CHELSA V2.1 1981–2010 climatology, 0.05° cells (each the mean of ~36 1 km pixels). Across the range: median and 10th–90th percentile of each month across the 1370 distinct grid cells holding 1606 of the 1607 in-range records (1 further cell with records at sea, by the elevation layer, left out); extremes and elevation at the typical cell 929:2152 (its coldest month's mean nightly low nearest the median across cells); its position is the cell centre. Extremes: NASA POWER (MERRA-2) daily 1981–2024, cell 43.50_-72.500, lapse-corrected -220 m at 6.5 °C/km. Elevation: ETOPO 2022, 164 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 the cells of the in-range records placed well enough to read one, not at the marker.

Evidence usedThe map marker rests on all 1917 georeferenced records inside the native range; the climate across the range on the 1606 of them in the land cells it reads, of 1607 placed to within 10 km; the map shows only the 543 openly licensed ones, which alone would put the marker 99 km away. 1 record outside the WCVP native range not used. 310 in-range records are placed to worse than 10 km, or with no stated accuracy (admitted only as a person's observation to three decimals), and stay on the map but off the climate.
How this section is made
The map marker: the openly licensed record nearest the middle of the densest 1° population of the 1917 in-range records; it decides nothing. Records outside the native range, living specimens and records marked introduced are not used; which records count.

Every source is recorded as having answered, reported nothing, refused, failed, not been asked, or answered twice where one answer is taken (“not taken: two items answered”), and, for a source asked when this page was built, when: the figures are as the source held them that day; a source read from a file (Kew's World Checklist, a GBIF download) says "as of" the file's day instead; a row carried from an earlier build of the page names that build instead. Only “nothing to report” is ever shown as an absence. Records came from 62 datasets via GBIF.org; each carries its own licence.
