Summary
Alchemilla flabellata, the fan lady's mantle, is a species of flowering plant in the family Rosaceae. It is native to central and southern Europe, Ukraine, and possibly central European Russia, and is locally extinct in Czechoslovakia. It prefers to grow in mountainous areas in calcareous meadows.

About the genus · Alchemilla
Alchemilla is a genus of herbaceous perennial plants in the family Rosaceae, with the common name lady's mantle applied generically as well as specifically to Alchemilla mollis when referred to as a garden plant. The plant used as a herbal tea or for medicinal usage such as gynaecological disorders is Alchemilla xanthochlora or in Middle Europe the so-called common lady's mantle Alchemilla vulgaris. There are between 800 and 1000 species, the majority native to cool temperate and subarctic regions of Europe and Asia, with a few species native to the mountains of Africa and the Americas.

Cultivation
Seasons
The rain rule reads no short rainy season: 70% of the median year's rain (997 mm of 1,347 mm) takes 8 months, April to June and August to December. Mean temperature moves 18.3 °C between the warmest and coldest month. Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: February to June and October to December.
Rain
1,347 mm in the median year at the habitat, 997 mm of it April to June and August to December. Wettest month October at 146 mm, driest month February at 73 mm. Across the grid cells of the range the year's total runs 958 mm to 2,041 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 1,360 mm, is the year's rain at the top of the page; the 1,347 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 42 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 44).
Warmth and air
Monthly means: the coldest month's mean nightly low -9.2 °C in January (across the grid cells of the range -15.3 °C to -3.2 °C), the warmest month's mean daily high 18.1 °C in July (median year across the grid cells of the range, CHELSA). Cold floor: none read. The nearest figure is -9.2 °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.
Relative humidity at the habitat: 58 to 62% 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.
Climate across the habitat
Habitat months, northern hemisphere
Mean daily high from -1 °C in Jan to 18 °C in Jul and Aug; mean nightly low from -9 °C in Jan and Feb to 8 °C in Jul and Aug. The cold quarter, Dec to Feb, is the three months around the coldest month's mean nightly low, centred on the 2 months in a row that tie for it. 1,347 mm of rain in the median year (the twelve monthly medians added), the wettest month Oct. The bands show the 10th to 90th percentile across 502 habitat cells. Beneath: daily light integral and relative humidity through the year, each on its own scale.

The daily extremes were not used: the correction for elevation, +1056 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 -24.2 °C, 1st-percentile night -13.0 °C.
