About the genus · Sonchus
Sonchus is a genus of flowering plants in the tribe Cichorieae within the family Asteraceae and are commonly known as sow thistles. Sowthistles are annual, biennial or perennial herbs, with or without rhizomes and a few are even woody.

Cultivation
Seasons
The rain rule reads a winter growing season: 70% of the median year's rain (258 mm of 335 mm) falls in November to March, cooler than the year (wet-season mean 16.8 °C against a yearly mean of 18.4 °C). Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: May to September.
Rain
335 mm in the median year at the habitat, 258 mm of it November to March. Wettest month December at 72 mm, driest month July at 2 mm; 3 months under 5 mm. Across the grid cells of the range the year's total runs 291 mm to 407 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 330 mm, is the year's rain at the top of the page; the 335 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: 21 to 48 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 19, the highest 90th-percentile month 49).
Warmth and air
Coldest: the 1st-percentile night over 44 years at a typical spot in the range is 14.0 °C, the absolute minimum 11.7 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 24.9 °C. Monthly means: the coldest month's mean nightly low 14.1 °C in February (across the grid cells of the range 12.0 °C to 15.4 °C), the warmest month's mean daily high 24.1 °C in August (median year across the grid cells of the range, CHELSA). Cold floor: 14.0 °C, which is the 1st-percentile night over 44 years at a typical spot in the range (NASA POWER).
Relative humidity at the habitat: 59 to 62% 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 +186 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 18 °C in Jan and Feb to 24 °C in Aug; mean nightly low from 14 °C in Jan and Feb to 20 °C in Aug and Sep. The cold quarter, Dec to Feb, is the three months around the coldest month's mean nightly low, centred on the 2 months in a row that tie for it. 335 mm of rain in the median year (the twelve monthly medians added), the wettest month Dec. The bands show the 10th to 90th percentile across 13 habitat cells. Over 44 years at a typical spot in the range (NASA POWER) the absolute minimum was 11.7 °C and the 99th-percentile day 24.9 °C; neither is dated to a month. Beneath: daily light integral and relative humidity through the year, each on its own scale.
