Summary

Lonicera ligustrina, the privet-like honeysuckle, is a species of honeysuckle found in the central and eastern Himalayas of Bhutan, India, Nepal, and in southern and central China. It grows as an evergreen, semi-evergreen, or deciduous shrub approximately 1.5-2.5 meters in height, with leathery or paper-like leaves 0.4-8 × 0.2-1.5 cm in size.

Rain rule: a summer growing season, May to September in the northern hemisphere (May to September at the habitat, northern). Habitat rain 1213 mm a year, wettest July at 223 mm, driest December at 18 mm (habitat calendar, northern hemisphere). Open sky over the habitat: 16 to 31 mol/m²/day. Cold floor -1.5 °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 September in the northern hemisphere (May to September 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 (883 mm of 1213 mm) falls in May to September, warmer than the year (wet-season mean 21.8 °C against a yearly mean of 15.2 °C). Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: November to March.

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.

1213 mm a year at the habitat, 883 mm of it May to September. Wettest month July at 223 mm, driest December at 18 mm. Across the envelope cells the year's total runs 848 mm to 1773 mm (10th to 90th percentile of each cell's own year) (median year across the envelope cells, CHELSA; habitat calendar, northern hemisphere).

Open sky over the habitat: 16 to 31 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 12, the highest 90th-percentile month 40).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is -1.5 °C, the absolute minimum -5.7 °C, about 10 frost nights a year (NASA POWER daily minima). Warmest: the 99th-percentile day is 33.4 °C. Monthly means: coldest night 0.5 °C in January (across the envelope cells -6.6 °C to 5.1 °C), warmest day 26.1 °C in July (median year across the envelope cells, CHELSA). Cold floor: -1.5 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).

Each figure is the median across the 162 grid cells holding the 196 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 1216:5662 (29.175, 103.125). Over 44 years there: absolute minimum -5.7 °C, 1st-percentile night -1.5 °C, 99th-percentile day 33.4 °C.
