Summary

Dais cotinifolia, known as the pompom tree, is a small Southern African tree belonging to the Thymelaeaceae family. It occurs along the east coast northwards from the Eastern Cape, inland along the Drakensberg escarpment through KwaZulu-Natal and the Transvaal, with an isolated population in the Eastern Highlands of Zimbabwe. It flowers profusely during the summer months and produces a multitude of pink, sweet-scented, globular flowerheads about 8 cm across.

Rain rule: a summer growing season, April to September in the northern hemisphere (October to March at the habitat, southern). Habitat rain 845 mm a year, wettest January at 130 mm, driest July at 17 mm (habitat calendar, southern hemisphere). Open sky over the habitat: 22 to 41 mol/m²/day. Cold floor 1.9 °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

Its year Rain rule: a summer growing season, April to September in the northern hemisphere (October to March at the habitat, southern).

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

The rain rule reads a summer growing season: 70% of the year's rain (661 mm of 845 mm) falls in October to March, warmer than the year (wet-season mean 19.2 °C against a yearly mean of 16.6 °C). Months are the habitat's, southern hemisphere; shifted six months for a northern-hemisphere collection: April to September.

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.

845 mm a year at the habitat, 661 mm of it October to March. Wettest month January at 130 mm, driest July at 17 mm. Across the envelope cells the year's total runs 642 mm to 1184 mm (10th to 90th percentile of each cell's own year) (median year across the envelope cells, CHELSA; habitat calendar, southern hemisphere).

Open sky over the habitat: 22 to 41 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 16, the highest 90th-percentile month 49).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is 1.9 °C, the absolute minimum -2.8 °C, 27 frost nights in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 38.8 °C. Monthly means: coldest night 5.7 °C in July (across the envelope cells 2.1 °C to 12.2 °C), warmest day 24.9 °C in February (median year across the envelope cells, CHELSA). Cold floor: 1.9 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).

Each figure is the median across the 382 grid cells holding the 699 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 2307:4142 (-25.375, 27.125). Over 44 years there: absolute minimum -2.8 °C, 1st-percentile night 1.9 °C, 99th-percentile day 38.8 °C.
