About the genus · Crocus

Crocus is a genus of seasonal flowering plants in the family Iridaceae comprising about 100 species of perennials growing from corms.

Quoted from Wikipedia, "Crocus", CC BY-SA 4.0.

Cultivation

Grouped as a bulb, tuber or caudex, listed under the genus Crocus in the archetype table, and Kew describes it as “tuberous geophyte”.

Seasons

The rain rule reads a winter growing season: 70% of the median year's rain (1,249 mm of 1,690 mm) falls in September to March, cooler than the year (wet-season mean 8.4 °C against a yearly mean of 12.3 °C). Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: March to September.

Rain

1,690 mm in the median year at the habitat, 1,249 mm of it September to March. Wettest month November at 233 mm, driest month July at 46 mm. Across the grid cells of the range the year's total runs 1,219 mm to 3,356 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 1,677 mm, is the year's rain at the top of the page; the 1,690 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: 10 to 44 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 9, the highest 90th-percentile month 45).

Warmth and air
Temperature

Coldest: the 1st-percentile night over 44 years at a typical spot in the range is -8.8 °C, the absolute minimum -17.3 °C, 2,921 frost nights in 44 years, 66.4 a year (NASA POWER daily minima). Warmest: the 99th-percentile day is 33.6 °C. Monthly means: the coldest month's mean nightly low 0.3 °C in January (across the grid cells of the range -4.8 °C to 2.4 °C), the warmest month's mean daily high 24.6 °C in July and August (median year across the grid cells of the range, CHELSA). Cold floor: -8.8 °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: 54 to 60% 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 +144 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.

Group. Listed under the genus Crocus in the archetype table, and Kew describes it as “tuberous geophyte”. A group is taken only where Kew's description of the species agrees with the table's listing. The table gives no figure and no prose; the cold floor is the habitat's alone.

How this section is made
Each figure is the median across the 22 grid cells holding the 28 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 934:3941 (43.275, 17.075). Over 44 years there: absolute minimum -17.3 °C, 1st-percentile night -8.8 °C, 99th-percentile day 33.6 °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 22 distinct grid cells holding 28 of the 28 in-range records; extremes and elevation at the typical cell 934:3941 (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_16.875, lapse-corrected +144 m at 6.5 °C/km. Elevation: ETOPO 2022, 683 m (cell mean).

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 2 datasets via GBIF.org; each carries its own licence.
