About the genus · Ceropegia

Ceropegia is a genus of plants within the family Apocynaceae, native to Africa, southern Asia, and Australia. It was named by Carl Linnaeus, who first described this genus in his Genera plantarum, which appeared in 1737. Linnaeus referred to the description and picture of a plant in the Horti Malabarici as the plant for which the genus was created. More on Wikipedia ›

Grouped as a cactus or succulent by the genus Ceropegia, which is reliably one kind of plant (archetype table). Rain rule: a winter growing season, May to September at the habitat (not shifted). Habitat rain 1162 mm a year, wettest August at 224 mm, driest January at 3 mm (habitat calendar, northern hemisphere). Open sky over the habitat: 26 to 40 mol/m²/day. Cold floor 13.9 °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 Ceropegia, 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: a winter growing season, May to September at the habitat (not shifted).

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

The rain rule reads a winter growing season: 70% of the year's rain (925 mm of 1162 mm) falls in May to September, cooler than the year (wet-season mean 25.6 °C against a yearly mean of 26.8 °C). Months are the habitat's, northern hemisphere, within 10° of the equator; with no thermal season there there is no season to reverse, so they are not shifted for a collection elsewhere.

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 1162 mm a year, wettest August at 224 mm, driest January at 3 mm (habitat calendar, northern hemisphere).

This species’ habitat figures, with their source.

1162 mm a year at the habitat, 925 mm of it May to September. Wettest month August at 224 mm, driest January at 3 mm; 2 months under 5 mm. Across the envelope cells the year's total runs 1141 mm to 1219 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: 26 to 40 mol/m²/day.

This species’ habitat figures, with their source.

Open sky over the habitat: 26 to 40 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 25, the highest 90th-percentile month 41).

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.

Warmth and air Cold floor 13.9 °C (1st-percentile habitat night, NASA POWER).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is 13.9 °C, the absolute minimum 11.2 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 38.1 °C. Monthly means: coldest night 19.4 °C in January (across the envelope cells 18.7 °C to 20.7 °C), warmest day 36.0 °C in February (median year across the envelope cells, CHELSA). Cold floor: 13.9 °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.

Humidity

Each figure is the median across the 12 grid cells holding the 15 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 1625:3652 (8.725, 2.625). Over 44 years there: absolute minimum 11.2 °C, 1st-percentile night 13.9 °C, 99th-percentile day 38.1 °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 12 distinct grid cells holding the 15 in-range records; extremes and elevation at the typical cell 1625:3652 (its coldest month's mean night nearest the median across cells); its position is the cell centre.
