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: a summer growing season, April to October in the northern hemisphere (October to April at the habitat, southern). Habitat rain 920 mm a year, wettest January at 121 mm, driest June at 35 mm (habitat calendar, southern hemisphere). Open sky over the habitat: 20 to 39 mol/m²/day. Cold floor 6.9 °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 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: a summer growing season, April to October in the northern hemisphere (October to April 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 (695 mm of 920 mm) falls in October to April, warmer than the year (wet-season mean 20.0 °C against a yearly mean of 18.1 °C). Months are the habitat's, southern hemisphere; shifted six months for a northern-hemisphere collection: April to October.

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 920 mm a year, wettest January at 121 mm, driest June at 35 mm (habitat calendar, southern hemisphere).

920 mm a year at the habitat, 695 mm of it October to April. Wettest month January at 121 mm, driest June at 35 mm. Across the envelope cells the year's total runs 622 mm to 1090 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: 20 to 39 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 17, the highest 90th-percentile month 48).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is 6.9 °C, the absolute minimum 3.5 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 34.0 °C. Monthly means: coldest night 10.3 °C in July (across the envelope cells 5.7 °C to 13.9 °C), warmest day 25.3 °C in February (median year across the envelope cells, CHELSA). Cold floor: 6.9 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).
