Summary

Coccothrinax argentata, commonly called the Florida silver palm, is a species of palm tree. It is native to south Florida, southeast Mexico, Colombia and to the West Indies, where it is found in the Bahamas, the southwest Caribbean and the Turks and Caicos Islands. Its natural habitat is rocky, calcareous soil in coastal scrubland and hammock communities.

Cultivation

Seasons

The rain rule reads a summer growing season: 70% of the median year's rain (903 mm of 1,241 mm) falls in May to October, warmer than the year (wet-season mean 26.8 °C against a yearly mean of 24.6 °C). Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: November to April.

Rain

1,241 mm in the median year at the habitat, 903 mm of it May to October. Wettest month June at 184 mm, driest month December at 46 mm. Across the grid cells of the range the year's total runs 983 mm to 1,543 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 1,193 mm, is the year's rain at the top of the page; the 1,241 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: 22 to 43 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 21, the highest 90th-percentile month 44).

Warmth and air
Temperature

Monthly means: the coldest month's mean nightly low 20.4 °C in January (across the grid cells of the range 16.3 °C to 22.6 °C), the warmest month's mean daily high 28.6 °C in August (median year across the grid cells of the range, CHELSA). Cold floor: none read. The nearest figure is 20.4 °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 that is mostly sea and are not used.

Humidity

Relative humidity at the habitat: 58 to 64% 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 read at a NASA POWER cell that is 24% land: neither it nor the next candidates whose coldest month's mean nightly low is within 2 °C of the median across cells sit in a POWER cell that is mostly land, and the rule reads a cold floor only from a cell that is mostly land, so none is read for this species. Nor is the coldest month's mean nightly low taken as one: it is a mean of a month's lows, not its coldest night. What that cell gave over 44 years: absolute minimum 12.0 °C, 1st-percentile night 17.4 °C, 99th-percentile day 30.5 °C.

How this section is made
Each figure is the median across the 73 grid cells on land that hold in-range records (223 records in those cells; 8 more cells hold records but no land by the elevation layer, so those records sit at sea and the cells are 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 1266:2054 (26.675, -77.275). 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 73 distinct grid cells holding 223 of the 264 in-range records (8 further cells with records at sea, by the elevation layer, left out); extremes and elevation at the typical cell 1266:2054 (its coldest month's mean nightly low nearest the median across cells, though its NASA POWER cell is only 24% land and none of the 11 next candidates within 2 °C of the median was mostly land); its position is the cell centre. Extremes: NASA POWER (MERRA-2) daily 1981–2024, cell 26.50_-77.500, lapse-corrected 0 m at 6.5 °C/km. Elevation: ETOPO 2022, 0 m (cell mean).

Evidence usedThe map marker rests on all 340 georeferenced records inside the native range; the climate across the range on the 223 of them in the land cells it reads, of 264 placed to within 10 km; the map shows only the 90 openly licensed ones, which alone would put the marker 3 km away. 20 records outside the WCVP native range not used. 76 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 340 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 23 datasets via GBIF.org; each carries its own licence.
