About the genus · Brunnera

Brunnera is a genus of flowering plants in the family Boraginaceae. They are rhizomatous perennials, native to the woodlands of Eastern Europe and North West Asia. They have hairy leaves and sprays of blue flowers in spring. More on Wikipedia ›

Rain rule: a summer growing season, May to November in the northern hemisphere (May to November at the habitat, northern). Habitat rain 662 mm a year, wettest July at 82 mm, driest March at 32 mm (habitat calendar, northern hemisphere). Open sky over the habitat: 2 to 35 mol/m²/day. Cold floor -30.0 °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

Its year Rain rule: a summer growing season, May to November in the northern hemisphere (May to November at the habitat, northern).

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 (467 mm of 662 mm) falls in May to November, warmer than the year (wet-season mean 11.0 °C against a yearly mean of 4.5 °C). Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: November 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.

662 mm a year at the habitat, 467 mm of it May to November. Wettest month July at 82 mm, driest March at 32 mm. Across the envelope cells the year's total runs 494 mm to 765 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: 2 to 35 mol/m²/day.

This species’ habitat figures, with their source.

Open sky over the habitat: 2 to 35 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 2, the highest 90th-percentile month 39).

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 -30.0 °C (1st-percentile habitat night, NASA POWER).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is -30.0 °C, the absolute minimum -44.0 °C, about 184 frost nights a year (NASA POWER daily minima). Warmest: the 99th-percentile day is 28.4 °C. Monthly means: coldest night -11.9 °C in February (across the envelope cells -18.2 °C to -10.8 °C), warmest day 22.9 °C in July (median year across the envelope cells, CHELSA). Cold floor: -30.0 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).

Each figure is the median across the 766 grid cells holding the 1436 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 674:4480 (56.275, 44.025). Over 44 years there: absolute minimum -44.0 °C, 1st-percentile night -30.0 °C, 99th-percentile day 28.4 °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 766 distinct grid cells holding the 1436 in-range records; extremes and elevation at the typical cell 674:4480 (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 56.50_43.750, lapse-corrected +54 m at 6.5 °C/km. Elevation: ETOPO 2022, 150 m (cell mean).
