About the genus · Heptapleurum
Heptapleurum is a genus of flowering plants in the family Araliaceae, the ivy or ginseng family. These plants are native to Southeast Asia: Malesia, Papuasia, southern China, Vietnam, the Indian Subcontinent, Tibet, Hainan, Taiwan, Japan, and Australia. The genus was phylogenetically resurrected from the genus Schefflera in 2020. More on Wikipedia ›

Cultivation
Seasons
The rain rule reads a sharp season: 70% of the median year's rain (2,871 mm of 3,970 mm) falls in June to August. The temperature curve is flat, 3.7 °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, northern hemisphere. The temperature curve moves under 4 °C between the warmest and coldest month, where the shift rule does not apply, so they are not shifted for a collection elsewhere.
Rain
3,970 mm in the median year at the habitat, 2,871 mm of it June to August. Wettest month July at 1,250 mm, driest month January at 6 mm. Across the grid cells of the range the year's total runs 2,631 mm to 5,088 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 4,202 mm, is the year's rain at the top of the page; the 3,970 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: 19 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 17, 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 12.4 °C, the absolute minimum 9.9 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 40.1 °C. Monthly means: the coldest month's mean nightly low 15.9 °C in January (across the grid cells of the range 15.2 °C to 17.6 °C), the warmest month's mean daily high 32.1 °C in April (median year across the grid cells of the range, CHELSA). Cold floor: 12.4 °C, which is the 1st-percentile night over 44 years at a typical spot in the range (NASA POWER).
Relative humidity at the habitat: 54 to 82% 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 +109 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.
Climate across the habitat
Habitat months, northern hemisphere
Mean daily high from 24 °C in Jul to 32 °C in Mar and Apr; mean nightly low from 16 °C in Jan, Feb and Dec to 21 °C in Apr, May and Jun. The cold quarter, Dec to Feb, is the three months around the coldest month's mean nightly low, centred on the 3 months in a row that tie for it. 3,970 mm of rain in the median year (the twelve monthly medians added), the wettest month Jul. The bands show the 10th to 90th percentile across 14 habitat cells. Over 44 years at a typical spot in the range (NASA POWER) the absolute minimum was 9.9 °C and the 99th-percentile day 40.1 °C; neither is dated to a month. Beneath: daily light integral and relative humidity through the year, each on its own scale.
