Summary
Kleinia petraea is a species of flowering plant in the genus Kleinia and family Asteraceae which was previously considered to be a species of Senecio. Native to Kenya and Tanzania, it is colloquially known as creeping jade, trailing jade or weeping jade due to its resemblance to the unrelated Jade plant (Crassula ovata).

About the genus · Kleinia
Kleinia is a genus of flowering plants in the sunflower family. Kleinia contains around 50 species and is distributed from Morocco and the Canary Islands, throughout Sub-Saharan Africa, the Arabian Peninsula, South Asia and Indochina. It is closely related to the genus Senecio but is distinguished primarily by having succulent stems or leaves.

Cultivation
Grouped as a cactus or succulent, listed under the genus Kleinia in the archetype table, and Kew describes it as “succulent subshrub”.
Seasons
The rain rule reads a sharp season: 70% of the median year's rain (645 mm of 848 mm) falls in November to January and March to May. The temperature curve is flat, 3.1 °C between the warmest and coldest month, so the growing-season rule does not infer a growing season from it. Months are the habitat's, southern hemisphere. The habitat lies within 10° of the equator, where the shift rule does not apply, so they are not shifted for a collection elsewhere.
Rain
848 mm in the median year at the habitat, 645 mm of it November to January and March to May. Wettest month April at 171 mm, driest month July at 22 mm. Across the grid cells of the range the year's total runs 682 mm to 1,213 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 916 mm, is the year's rain at the top of the page; the 848 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: 33 to 43 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 26, the highest 90th-percentile month 44).
Warmth and air
Coldest: the 1st-percentile night over 44 years at a typical spot in the range is 10.5 °C, the absolute minimum 8.1 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 32.4 °C. Monthly means: the coldest month's mean nightly low 12.4 °C in July (across the grid cells of the range 9.6 °C to 14.3 °C), the warmest month's mean daily high 26.2 °C in February (median year across the grid cells of the range, CHELSA). Cold floor: 10.5 °C, which is the 1st-percentile night over 44 years at a typical spot in the range (NASA POWER).
Relative humidity at the habitat: 55 to 61% 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 -20 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 Kleinia in the archetype table, and Kew describes it as “succulent subshrub”. 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
Habitat months, southern hemisphere
Mean daily high from 22 °C in Jul and Aug to 26 °C in Feb and Mar; mean nightly low from 12 °C in Jul to 15 °C in Mar and Apr. The cold quarter, Jun to Aug, is the three months around the coldest month's mean nightly low. 848 mm of rain in the median year (the twelve monthly medians added), the wettest month Apr. The bands show the 10th to 90th percentile across 27 habitat cells. Over 44 years at a typical spot in the range (NASA POWER) the absolute minimum was 8.1 °C and the 99th-percentile day 32.4 °C; neither is dated to a month. Beneath: daily light integral and relative humidity through the year, each on its own scale.
