Summary

Pseudogynoxys chenopodioides, known commonly as Mexican flamevine, orange-flowered groundsel and orange glow vine, is a climber in the family Asteraceae, native to Central America and northern South America. It is a vigorous vine with thick evergreen, deep green leaves and bright orange daisy-like flowers, which are borne in clusters, and usually bloom all year round.

Rain rule: a summer growing season, June to October in the northern hemisphere (June to October at the habitat, northern). Habitat rain 1254 mm a year, wettest September at 230 mm, driest March at 25 mm (habitat calendar, northern hemisphere). Open sky over the habitat: 26 to 40 mol/m²/day. Cold floor 9.5 °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, June to October in the northern hemisphere (June to October 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 (942 mm of 1254 mm) falls in June to October, warmer than the year (wet-season mean 23.5 °C against a yearly mean of 22.4 °C). Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: December to April.

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.

Across the envelope cells the year's total runs 730 mm to 2382 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: 26 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 20, the highest 90th-percentile month 44).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is 9.5 °C, the absolute minimum 1.9 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 43.7 °C. Monthly means: coldest night 15.2 °C in January (across the envelope cells 9.7 °C to 20.6 °C), warmest day 29.0 °C in May (median year across the envelope cells, CHELSA). Cold floor: 9.5 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).
