Summary

Sedum album, the white stonecrop, is a flowering plant of the genus Sedum in the family Crassulaceae. It is found in the northern temperate regions of the world, often growing in crevices or free-draining rocky soil. As a long-day plant it grows vegetatively for most of the year and flowers in summer.

About the genus · Sedum

Sedum is a large genus of flowering plants in the family Crassulaceae, members of which are commonly known as stonecrops. The genus has been described as containing up to 600 species, subsequently reduced to 400–500. They are leaf succulents found primarily in the Northern Hemisphere, but extending into the southern hemisphere in Africa and South America. More on Wikipedia ›

Rain rule: no season, 70% of the rain takes 8 months (June to January in the northern hemisphere). Habitat rain 886 mm a year, wettest October at 88 mm, driest April at 54 mm (habitat calendar, northern hemisphere). Open sky over the habitat: 6 to 36 mol/m²/day. Cold floor -10.4 °C (1st-percentile habitat night, NASA POWER).
Each sentence is one card's own one-line form, written by the same rule as the card (Its year, Rain, Light, Temperature); the note cannot say what a card does not. Months are given for the northern hemisphere (set your site in Settings to change this), and the habitat's own alongside. The cards · the figures.

Cultivation

Grouped as a cactus or succulent by the genus Sedum, which is reliably one kind of plant (archetype table). The table holds no figure for this group, which spans too much for one minimum; the cold floor is the habitat's alone, and no prose comes from the table.

Its year Rain rule: no season, 70% of the rain takes 8 months (June to January in the northern hemisphere).

This species’ habitat figures, and what two fixed rules read from them.

The rain rule reads no season: 70% of the year's rain (640 mm of 886 mm) takes 8 months, June to January. Mean temperature moves 15.4 °C between the warmest and coldest month. Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: December to July.

Read from the median year of CHELSA monthly rainfall and mean temperature across the envelope cells: 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 gives a season to reverse. A reading of the curves, not an observation of the plant.

Rain Habitat rain 886 mm a year, wettest October at 88 mm, driest April at 54 mm (habitat calendar, northern hemisphere).

This species’ habitat figures, with their source.

886 mm a year at the habitat, 640 mm of it June to January. Wettest month October at 88 mm, driest April at 54 mm. Across the envelope cells the year's total runs 618 mm to 1312 mm (10th to 90th percentile of each cell's own year) (median year across the envelope cells, CHELSA; habitat calendar, northern hemisphere).

CHELSA monthly precipitation, median year across the envelope cells. The rain that falls where the species is recorded; nothing about how the plant takes water.

Light Open sky over the habitat: 6 to 36 mol/m²/day.

Open sky over the habitat: 6 to 36 mol/m²/day across the year (daily light integral, median year across the envelope cells, CHELSA; the lowest 10th-percentile month across the cells is 3, the highest 90th-percentile month 47).

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

Coldest: the 1st-percentile night over 44 years at the typical cell is -10.4 °C, the absolute minimum -23.7 °C, about 57 frost nights a year (NASA POWER daily minima). Warmest: the 99th-percentile day is 32.5 °C. Monthly means: coldest night 0.3 °C in January (across the envelope cells -5.3 °C to 3.6 °C), warmest day 22.4 °C in July (median year across the envelope cells, CHELSA). Cold floor: -10.4 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).

NASA POWER daily minima and maxima 1981–2024 at the typical cell, lapse-corrected to its elevation; CHELSA monthly means, median year across the envelope cells, CHELSA. The cold floor is the figure named in its sentence. Not a measured survival limit for any plant in a pot.

Climate across the habitat

Habitat climate through the yearMean day from 5 °C in Jan to 22 °C in Jul; mean night from 0 °C in Jan to 14 °C in Jul. The cold quarter, Dec to Feb, is the three months around the coldest night. 886 mm of rain a year, most in Oct. The bands show the 10th to 90th percentile across 519 habitat cells. Over 44 years at the typical cell the absolute minimum was -23.7 °C and the 99th-percentile day 32.5 °C; neither is dated to a month.

Each figure is the median across the 519 grid cells holding the 582 in-range records, with the 10th–90th percentile span across those cells after the slash where it differs. Extremes and elevation were read at the typical cell 870:3733 (46.475, 6.675). Over 44 years there: absolute minimum -23.7 °C, 1st-percentile night -10.4 °C, 99th-percentile day 32.5 °C. Normals: CHELSA V2.1 1981–2010 climatology, 0.05° cells (each the mean of ~36 1 km pixels). Envelope: median and 10th–90th percentile of each month across the 519 distinct grid cells holding the 582 in-range records; extremes and elevation at the typical cell 870:3733 (its coldest month's mean night nearest the median across cells); its position is the cell centre. Extremes: NASA POWER (MERRA-2) daily 1981–2024, cell 46.50_6.875, lapse-corrected -688 m at 6.5 °C/km. Elevation: ETOPO 2022, 368 m (cell mean).

Similar habitat climate the 6 species whose habitat climate is nearest this one's: mean day and night, month by month, and rain on a log scale, in calendar order, so a habitat with the same seasons six months out is far, not near. Nothing else counts: not range, not family.
