Summary
Kalanchoe beauverdii, or Beauverd's widow's-thrill, is a climbing succulent species of Kalanchoe subg. Bryophyllum native to Madagascar. The species used to include many different forms with great variations. Now the broad-sense K. beauverdii has been treated as a series, Kalanchoe ser. Vilana, which includes four species: K. beauverdii, K. costantinii, K. guignardii, and K. scandens. The narrow-sense K. beauverdii differs from the other species of the series in its petiolate leaves.

About the genus · Kalanchoe
Kalanchoe, , is a genus of about 125 species of tropical, succulent plants in the stonecrop family Crassulaceae, mainly native to Madagascar and tropical Africa. A Kalanchoe species was one of the first plants to be sent into space, sent on a resupply to the Soviet Salyut 6 space station in 1979.

Cultivation
Grouped as a cactus or succulent, listed under the genus Kalanchoe in the archetype table, and Kew describes it as “climbing succulent”.
Seasons
The rain rule reads a summer growing season: 70% of the median year's rain (506 mm of 715 mm) falls in November to March, warmer than the year (wet-season mean 26.3 °C against a yearly mean of 23.9 °C). Months are the habitat's, southern hemisphere; shifted six months for a northern-hemisphere collection: May to September.
Rain
715 mm in the median year at the habitat, 506 mm of it November to March. Wettest month January at 147 mm, driest month August at 17 mm. Across the grid cells of the range the year's total runs 461 mm to 1,045 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 710 mm, is the year's rain at the top of the page; the 715 mm here is the median year's, the twelve monthly medians added, which the rain rule reads. Habitat calendar, southern hemisphere; median year across the grid cells of the range, CHELSA.
Light
Open sky over the habitat: 24 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 22, the highest 90th-percentile month 48).
Warmth and air
Coldest: the 1st-percentile night over 44 years at a typical spot in the range is 13.2 °C, the absolute minimum 10.4 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 37.6 °C. Monthly means: the coldest month's mean nightly low 16.0 °C in July (across the grid cells of the range 14.4 °C to 17.9 °C), the warmest month's mean daily high 31.4 °C in December (median year across the grid cells of the range, CHELSA). Cold floor: 13.2 °C, which is the 1st-percentile night over 44 years at a typical spot in the range (NASA POWER).
Relative humidity at the habitat: 57 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. NASA POWER daily minima and maxima over 44 years at a typical spot in the range, lapse-corrected -55 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 Kalanchoe in the archetype table, and Kew describes it as “climbing succulent”. 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.
Climate across the habitat
From few records: this habitat climate is read from 5 records in 4 grid cells; a page says so under 12 records or 5 cells, and shows the figures as read.
Habitat months, southern hemisphere
Mean daily high from 26 °C in Jun and Jul to 31 °C in Jan, Feb, Mar, Nov and Dec; mean nightly low from 16 °C in Jul and Aug to 23 °C in Jan, Feb and Mar. The cold quarter, Jun to Aug, is the three months around the coldest month's mean nightly low, centred on the 2 months in a row that tie for it. 715 mm of rain in the median year (the twelve monthly medians added), the wettest month Jan. The bands show the 10th to 90th percentile across 4 habitat cells. Over 44 years at a typical spot in the range (NASA POWER) the absolute minimum was 10.4 °C and the 99th-percentile day 37.6 °C; neither is dated to a month. Beneath: daily light integral and relative humidity through the year, each on its own scale.
