Summary
Solidago altissima, the tall goldenrod or late goldenrod, is a North American species of goldenrod in the family Asteraceae which is widespread across much of Canada, the United States, and northern Mexico. It is common in much of its range and fairly tolerant of landscapes which have been disturbed by humans. It has become naturalized in many parts of the world.

About the genus · Solidago
Solidago, commonly called goldenrod, is a genus of about 100 to 120 species of flowering plants in the family Asteraceae. Most are herbaceous perennial species found in open areas such as meadows, prairies, and savannas. They are mostly native to North America, including Mexico; a few species are native to South America and Eurasia. More on Wikipedia ›

Cultivation
Its year Rain rule: no season, 70% of the rain takes 8 months (April to November 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 (779 mm of 1078 mm) takes 8 months, April to November. Mean temperature moves 25.0 °C between the warmest and coldest month. Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: October to May.
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 1078 mm a year, wettest June at 110 mm, driest February at 66 mm (habitat calendar, northern hemisphere).

1078 mm a year at the habitat, 779 mm of it April to November. Wettest month June at 110 mm, driest February at 66 mm. Across the envelope cells the year's total runs 773 mm to 1446 mm (10th to 90th percentile of each cell's own year) (median year across the envelope cells, CHELSA; habitat calendar, northern hemisphere).
CHELSA monthly precipitation, median year across the envelope cells. The rain that falls where the species is recorded; nothing about how the plant takes water.
Light Open sky over the habitat: 12 to 40 mol/m²/day.
This species’ habitat figures, with their source.
Open sky over the habitat: 12 to 40 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 8, the highest 90th-percentile month 44).
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.
Warmth and air Cold floor -15.4 °C (1st-percentile habitat night, NASA POWER).
This species’ habitat figures, with their source.
Coldest: the 1st-percentile night over 44 years at the typical cell is -15.4 °C, the absolute minimum -27.4 °C, about 109 frost nights a year (NASA POWER daily minima). Warmest: the 99th-percentile day is 39.7 °C. Monthly means: coldest night -4.5 °C in January (across the envelope cells -13.4 °C to 6.4 °C), warmest day 29.3 °C in July (median year across the envelope cells, CHELSA). Cold floor: -15.4 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).
NASA POWER daily minima and maxima 1981–2024 at the typical cell, lapse-corrected to its elevation; CHELSA monthly means, median year across the envelope cells, CHELSA. The cold floor is the figure named in its sentence. Not a measured survival limit for any plant in a pot.
Relative humidity at the habitat: 56 to 59% across the year (monthly means, median year across the envelope cells, CHELSA). A figure about the air, saying nothing about how the plant takes water.

Each figure is the median across the 1260 grid cells holding the 1409 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 1032:1668 (38.375, -96.575). Over 44 years there: absolute minimum -27.4 °C, 1st-percentile night -15.4 °C, 99th-percentile day 39.7 °C. Normals: CHELSA V2.1 1981–2010 climatology, 0.05° cells (each the mean of ~36 1 km pixels). Envelope: median and 10th–90th percentile of each month across the 1260 distinct grid cells holding the 1409 in-range records; extremes and elevation at the typical cell 1032:1668 (its coldest month's mean night nearest the median across cells); its position is the cell centre. Extremes: NASA POWER (MERRA-2) daily 1981–2024, cell 38.50_-96.875, lapse-corrected -40 m at 6.5 °C/km. Elevation: ETOPO 2022, 380 m (cell mean).
