About the genus · Clerodendrum

Clerodendrum is a genus of flowering plants formerly placed in the family Verbenaceae, but now considered to belong to the Lamiaceae (mint) family. Its common names include glorybower, bagflower, pagoda flower and bleeding-heart. It is currently classified in the subfamily Ajugoideae, being one of several genera transferred from Verbenaceae to Lamiaceae in the 1990s, based on phylogenetic analysis of morphological and molecular data.

Rain rule: a summer growing season, May to September in the northern hemisphere (May to September at the habitat, northern). Habitat rain 1631 mm a year, wettest July at 289 mm, driest December at 21 mm (habitat calendar, northern hemisphere). Open sky over the habitat: 23 to 36 mol/m²/day. Cold floor 7.7 °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 (1241 mm of 1631 mm) falls in May to September, warmer than the year (wet-season mean 25.9 °C against a yearly mean of 22.1 °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.

1631 mm a year at the habitat, 1241 mm of it May to September. Wettest month July at 289 mm, driest December at 21 mm. Across the envelope cells the year's total runs 1095 mm to 2773 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: 23 to 36 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 14, the highest 90th-percentile month 40).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is 7.7 °C, the absolute minimum 5.0 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 32.6 °C. Monthly means: coldest night 10.6 °C in January (across the envelope cells 4.3 °C to 19.7 °C), warmest day 28.6 °C in June (median year across the envelope cells, CHELSA). Cold floor: 7.7 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).

Each figure is the median across the 62 grid cells holding the 69 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 1594:5150 (10.275, 77.525). Over 44 years there: absolute minimum 5.0 °C, 1st-percentile night 7.7 °C, 99th-percentile day 32.6 °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 62 distinct grid cells holding the 69 in-range records; extremes and elevation at the typical cell 1594:5150 (its coldest month's mean night nearest the median across cells); its position is the cell centre.
