About the genus · Crassula

Crassula is a genus of succulent plants containing about 200 accepted species, including the popular jade plant. They are members of the stonecrop family (Crassulaceae) and are native to many parts of the globe, but cultivated varieties originate almost exclusively from species from the Eastern Cape of South Africa.

In short condensed by rule from the cultivation cards · not written by a person

Grouped as a cactus or succulent by the genus Crassula, which is reliably one kind of plant (archetype table). Rain rule: no season, 70% of the rain takes 8 months (November to June in the northern hemisphere). Habitat rain 562 mm a year, wettest August at 61 mm, driest February at 30 mm (habitat calendar, southern hemisphere). Open sky over the habitat: 13 to 48 mol/m²/day. Cold floor 0.6 °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 Crassula, 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: no season, 70% of the rain takes 8 months (November to June in the northern hemisphere).

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

The rain rule reads no season: 70% of the year's rain (426 mm of 562 mm) takes 8 months, May to December. Mean temperature moves 12.0 °C between the warmest and coldest month. Months are the habitat's, southern hemisphere; shifted six months for a northern-hemisphere collection: November to June.

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 562 mm a year, wettest August at 61 mm, driest February at 30 mm (habitat calendar, southern hemisphere).

562 mm a year at the habitat, 426 mm of it May to December. Wettest month August at 61 mm, driest February at 30 mm. Across the envelope cells the year's total runs 360 mm to 1043 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: 13 to 48 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 11, the highest 90th-percentile month 51).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is 0.6 °C, the absolute minimum -2.9 °C, about 2 frost nights a year (NASA POWER daily minima). Warmest: the 99th-percentile day is 41.9 °C. Monthly means: coldest night 5.1 °C in July (across the envelope cells 3.0 °C to 8.5 °C), warmest day 26.9 °C in January (median year across the envelope cells, CHELSA). Cold floor: 0.6 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).

Each figure is the median across the 670 grid cells holding the 828 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 2511:6483 (-35.575, 144.175). Over 44 years there: absolute minimum -2.9 °C, 1st-percentile night 0.6 °C, 99th-percentile day 41.9 °C.
