About the genus · Verbesina
Verbesina, many species of which have crownbeard as part of their common names, is a genus of flowering plants, in the family Asteraceae. It is a large genus of about 350 species.

Cultivation
Seasons
The rain rule reads a sharp season: 70% of the median year's rain (1,329 mm of 1,860 mm) falls in April to May and July to November. The temperature curve is flat, 3.8 °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
1,860 mm in the median year at the habitat, 1,329 mm of it April to May and July to November. Wettest month September at 221 mm, driest month February at 73 mm. Across the grid cells of the range the year's total runs 1,332 mm to 2,242 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 1,845 mm, is the year's rain at the top of the page; the 1,860 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: 28 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 24, the highest 90th-percentile month 43).
Warmth and air
Coldest: the 1st-percentile night over 44 years at a typical spot in the range is 20.9 °C, the absolute minimum 19.2 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 31.0 °C. Monthly means: the coldest month's mean nightly low 19.9 °C in January and February (across the grid cells of the range 17.5 °C to 23.3 °C), the warmest month's mean daily high 29.9 °C in July and August (median year across the grid cells of the range, CHELSA). Cold floor: 20.9 °C, which is the 1st-percentile night over 44 years at a typical spot in the range (NASA POWER).
Relative humidity at the habitat: 62 to 67% 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 +127 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 26 °C in Jan, Feb and Dec to 30 °C in Jul and Aug; mean nightly low from 20 °C in Jan, Feb and Mar to 24 °C in Jun, Jul, Aug and Sep. The cold quarter, Jan to Mar, is the three months around the coldest month's mean nightly low, centred on the 3 months in a row that tie for it. 1,860 mm of rain in the median year (the twelve monthly medians added), the wettest month Sep. The bands show the 10th to 90th percentile across 42 habitat cells. Over 44 years at a typical spot in the range (NASA POWER) the absolute minimum was 19.2 °C and the 99th-percentile day 31.0 °C; neither is dated to a month. Beneath: daily light integral and relative humidity through the year, each on its own scale.
