About the genus · Dichondra

Dichondra is a small genus of flowering plants in the morning glory family, Convolvulaceae. They are prostrate, perennial, herbaceous plants, with creeping stems which take root readily at the leaf nodes. The flowers are white, greenish or yellowish, 2–3 mm (0.079–0.118 in) diameter.

Rain rule: a summer growing season, May to September in the northern hemisphere (May to September at the habitat, northern). Habitat rain 527 mm a year, wettest July at 101 mm, driest March at 10 mm (habitat calendar, northern hemisphere). Open sky over the habitat: 29 to 46 mol/m²/day. Cold floor 2.0 °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.

Also known as Dichondra argentea Humb. & Bonpl.; Dichondra evolvulacea var. argentea (Willd.) Kuntze.

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 (399 mm of 527 mm) falls in May to September, warmer than the year (wet-season mean 19.7 °C against a yearly mean of 16.7 °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.

527 mm a year at the habitat, 399 mm of it May to September. Wettest month July at 101 mm, driest March at 10 mm. Across the envelope cells the year's total runs 394 mm to 959 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: 29 to 46 mol/m²/day.

Open sky over the habitat: 29 to 46 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 18, the highest 90th-percentile month 51).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is 2.0 °C, the absolute minimum -2.1 °C, 33 frost nights in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 31.8 °C. Monthly means: coldest night 5.5 °C in January (across the envelope cells 2.0 °C to 7.7 °C), warmest day 27.5 °C in May (median year across the envelope cells, CHELSA). Cold floor: 2.0 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).

Each figure is the median across the 761 grid cells holding the 1221 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 1409:1615 (19.525, -99.225). Over 44 years there: absolute minimum -2.1 °C, 1st-percentile night 2.0 °C, 99th-percentile day 31.8 °C.
