Summary

Cyclamen repandum, the spring sowbread, is a species of flowering plant in the family Primulaceae, native to southern Europe and some Mediterranean islands. It is the most widespread of a group of cyclamens (genus Cyclamen subgenus Psilanthum) with wide, heart-shaped leaves, often coarsely toothed or lobed, and late spring-blooming flowers with long, slender petals.

About the genus · Cyclamen

Cyclamen is a genus of 25 species of perennial flowering plants in the family Primulaceae. In English, it is known by the common name sowbread, or, by the genus name as cyclamen. The species are native to Europe and the Mediterranean Basin east to the Caucasus and Iran, with one species in Somalia. More on Wikipedia ›

Cultivation

Grouped as a bulb, tuber or caudex, listed under the genus Cyclamen 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 (695 mm of 943 mm) falls in September to January and March to April, cooler than the year (wet-season mean 11.3 °C against a yearly mean of 14.0 °C). Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: March to July and September to October.

Rain

943 mm in the median year at the habitat, 695 mm of it September to January and March to April. Wettest month November at 129 mm, driest month July at 22 mm. Across the grid cells of the range the year's total runs 678 mm to 1,354 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 957 mm, is the year's rain at the top of the page; the 943 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 46 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 8, the highest 90th-percentile month 48).

Warmth and air
Temperature

Coldest: the 1st-percentile night over 44 years at a typical spot in the range is -0.4 °C, the absolute minimum -7.4 °C, 211 frost nights in 44 years, 4.8 a year (NASA POWER daily minima). Warmest: the 99th-percentile day is 36.9 °C. Monthly means: the coldest month's mean nightly low 2.9 °C in February (across the grid cells of the range -1.6 °C to 7.7 °C), the warmest month's mean daily high 26.2 °C in August (median year across the grid cells of the range, CHELSA). Cold floor: -0.4 °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 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 -141 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 Cyclamen 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 755 grid cells on land that hold in-range records (1506 records in those cells; 2 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 970:3862 (41.475, 13.125). Over 44 years there: absolute minimum -7.4 °C, 1st-percentile night -0.4 °C, 99th-percentile day 36.9 °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 755 distinct grid cells holding 1506 of the 1508 in-range records (2 further cells with records at sea, by the elevation layer, left out); extremes and elevation at the typical cell 970:3862 (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 41.50_13.125, lapse-corrected -141 m at 6.5 °C/km. Elevation: ETOPO 2022, 106 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 1641 georeferenced records inside the native range; the climate across the range on the 1506 of them in the land cells it reads, of 1508 placed to within 10 km; the map shows only the 1025 openly licensed ones, which alone would put the marker 2 km away. 132 records outside the WCVP native range not used. 133 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 1641 in-range records; it decides nothing. Records outside the native range, living specimens and records marked introduced are not used; which records count.
