About the genus · Cuphea

Cuphea is a genus containing about 260 species of annual and perennial flowering plants native to warm temperate to tropical regions of the Americas. The species range from low-growing herbaceous plants to semi-woody shrubs up to 2 m tall. Commonly they are known as cupheas, or, in the case of some species, as cigar plants. More on Wikipedia ›

Cultivation

Seasons

The rain rule reads a summer growing season: 70% of the median year's rain (785 mm of 1,036 mm) falls in June to September, warmer than the year (wet-season mean 16.9 °C against a yearly mean of 15.7 °C). Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: December to March.

Rain

1,036 mm in the median year at the habitat, 785 mm of it June to September. Wettest month July at 209 mm, driest month December at 10 mm. Across the grid cells of the range the year's total runs 586 mm to 1,812 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 1,055 mm, is the year's rain at the top of the page; the 1,036 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: 30 to 45 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 25, the highest 90th-percentile month 48).

Warmth and air
Temperature

Monthly means: the coldest month's mean nightly low 6.3 °C in January (across the grid cells of the range 2.9 °C to 11.1 °C), the warmest month's mean daily high 24.4 °C in April (median year across the grid cells of the range, CHELSA). Cold floor: none read. The nearest figure is 6.3 °C, the coldest month's mean nightly low, January, in the median year (CHELSA); a month's mean of its nightly lows is warmer than the nights a floor is read from. The daily extremes were read at a weather cell whose ground is too far above or below the typical spot to correct for, and are not used.

Humidity

Relative humidity at the habitat: 50 to 67% 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. CHELSA monthly means, median year across the grid cells of the range. No cold floor is read without a daily extremes series; the coldest month's mean nightly low named in its sentence is not one. Not a measured survival limit for any plant in a pot.

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

The daily extremes were not used: the correction for elevation, +1008 m, is beyond the 1,000 m either way that a lapse rate is applied over, so the weather cell's ground is other terrain than the typical spot's. So no cold floor is read for this species, and the coldest month's mean nightly low is not taken as one. What that cell gave, so corrected, over 44 years: absolute minimum -9.0 °C, 1st-percentile night -0.9 °C.

How this section is made
Each figure is the median across the 669 grid cells holding the 1245 in-range records, 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 1408:1659 (19.575, -97.025). 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 669 distinct grid cells holding 1245 of the 1245 in-range records; extremes and elevation at the typical cell 1408:1659 (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 19.50_-96.875, lapse-corrected +1008 m at 6.5 °C/km. Elevation: ETOPO 2022, 2141 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 1557 georeferenced records inside the native range; the climate across the range on the 1245 of them placed to within 10 km; the map shows only the 968 openly licensed ones, which alone would put the marker 34 km away. 1 record outside the WCVP native range not used. 312 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 1557 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 68 datasets via GBIF.org; each carries its own licence.
