About the genus · Talinum

Talinum is a genus of herbaceous succulent plants in the family Talinaceae whose common names include fameflower. It includes 27 species native to tropical and subtropical regions of the Americas, sub-Saharan Africa, the Arabian Peninsula, Indian subcontinent, and Myanmar. Several species bear edible leaves, and Talinum fruticosum is widely grown in tropical regions as a leaf vegetable. More on Wikipedia ›

Grouped as a cactus or succulent by the genus Talinum, which is reliably one kind of plant (archetype table). Rain rule: a summer growing season, May to September in the northern hemisphere (November to March at the habitat, southern). Habitat rain 829 mm a year, wettest March at 138 mm, driest July at 11 mm (habitat calendar, southern hemisphere). Open sky over the habitat: 19 to 40 mol/m²/day. Cold floor 3.1 °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

Grouped as a cactus or succulent by the genus Talinum, which is reliably one kind of plant (archetype table). The table holds no figure for this group, which spans too much for one minimum; the cold floor is the habitat's alone, and no prose comes from the table.

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

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 (606 mm of 829 mm) falls in November to March, warmer than the year (wet-season mean 24.6 °C against a yearly mean of 21.7 °C). Months are the habitat's, southern hemisphere; shifted six months for a northern-hemisphere collection: May to September.

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.

Rain Habitat rain 829 mm a year, wettest March at 138 mm, driest July at 11 mm (habitat calendar, southern hemisphere).

829 mm a year at the habitat, 606 mm of it November to March. Wettest month March at 138 mm, driest July at 11 mm. Across the envelope cells the year's total runs 505 mm to 1989 mm (10th to 90th percentile of each cell's own year) (median year across the envelope cells, CHELSA; habitat calendar, southern 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: 19 to 40 mol/m²/day.

This species’ habitat figures, with their source.

Open sky over the habitat: 19 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 17, the highest 90th-percentile month 42).

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.

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is 3.1 °C, the absolute minimum -1.7 °C, 14 frost nights in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 43.3 °C. Monthly means: coldest night 12.4 °C in July (across the envelope cells 11.0 °C to 16.2 °C), warmest day 29.4 °C in January (median year across the envelope cells, CHELSA). Cold floor: 3.1 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).

Natural habitat

Native range as published by WCVP; the marker is where the records are densest and decides nothing: the climate was read across every in-range record's cell, not at the marker.
