Summary

Solidago canadensis, known as Canada goldenrod or Canadian goldenrod, is an herbaceous perennial plant of the family Asteraceae. It forms colonies of upright growing plants, with many small yellow flowers in a branching inflorescence held above the foliage. It is native to northeastern and north-central North America and is an invasive plant in other parts of the continent and several areas worldwide, including Eurasia.

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 ›

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

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 (712 mm of 972 mm) takes 8 months, April to November. Mean temperature moves 26.4 °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 972 mm a year, wettest June at 97 mm, driest February at 59 mm (habitat calendar, northern hemisphere).

This species’ habitat figures, with their source.

972 mm a year at the habitat, 712 mm of it April to November. Wettest month June at 97 mm, driest February at 59 mm. Across the envelope cells the year's total runs 870 mm to 1162 mm (10th to 90th percentile of each cell's own year) (median year across the envelope cells, CHELSA; habitat calendar, northern hemisphere).

Light Open sky over the habitat: 9 to 40 mol/m²/day.

This species’ habitat figures, with their source.

Open sky over the habitat: 9 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 42).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is -22.2 °C, the absolute minimum -38.3 °C, about 134 frost nights a year (NASA POWER daily minima). Warmest: the 99th-percentile day is 34.9 °C. Monthly means: coldest night -8.6 °C in January (across the envelope cells -14.3 °C to -4.7 °C), warmest day 26.8 °C in July (median year across the envelope cells, CHELSA). Cold floor: -22.2 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).

Climate across the habitat

Habitat climate through the yearMean day from -1 °C in Jan to 27 °C in Jul; mean night from -9 °C in Jan to 18 °C in Jul. The cold quarter, Dec to Feb, is the three months around the coldest night. 972 mm of rain a year, most in Jun. The bands show the 10th to 90th percentile across 20 habitat cells. Over 44 years at the typical cell the absolute minimum was -38.3 °C and the 99th-percentile day 34.9 °C; neither is dated to a month.

Each figure is the median across the 20 grid cells holding the 21 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 973:1821 (41.325, -88.925). Over 44 years there: absolute minimum -38.3 °C, 1st-percentile night -22.2 °C, 99th-percentile day 34.9 °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 20 distinct grid cells holding the 21 in-range records; extremes and elevation at the typical cell 973:1821 (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 41.50_-88.750, lapse-corrected -51 m at 6.5 °C/km. Elevation: ETOPO 2022, 162 m (cell mean).

Similar habitat climate the 6 species whose habitat climate is nearest this one's: mean day and night, month by month, and rain on a log scale, in calendar order, so a habitat with the same seasons six months out is far, not near. Nothing else counts: not range, not family.
