Summary
Begonia foliosa is a species of flowering plant in the family Begoniaceae, native to Colombia and Venezuela. It is a shrublike begonia growing to 1 metre (3.3 ft), bearing succulent, pendent stems 45 centimetres (18 in) long, thickly clothed with glossy oval green leaves, and producing panicles of small white flowers. The variety commonly cultivated is B. foliosa var. miniata with pink or red flowers. As it does not tolerate temperatures below 0 °C (32 °F), in temperate regions it requires winter protection.

About the genus · Begonia
Begonia is a genus of perennial flowering plants in the family Begoniaceae. The genus contains more than 2,000 different plant species, distributed primarily across tropical and subtropical regions of Africa, Asia, and Central and South America, with Africa considered the center of origin. Some species are commonly grown indoors as ornamental houseplants in cooler climates, or cultivated outside in summertime for their bright colorful flowers, which have petals but no sepals.

Cultivation
Grouped as a tropical foliage plant, listed under the genus Begonia in the archetype table, and Kew describes it as “subshrub or shrub”, “wet tropical”.
Seasons
The rain rule reads no short rainy season: 70% of the median year's rain (1,884 mm of 2,458 mm) takes 8 months, March to June and September to December. Mean temperature moves 0.6 °C between the warmest and coldest month. Months are the habitat's, northern hemisphere. The habitat lies within 10° of the equator, where the shift rule does not apply, so they are not shifted for a collection elsewhere.
Rain
2,458 mm in the median year at the habitat, 1,884 mm of it March to June and September to December. Wettest month April at 297 mm, driest month July at 131 mm. Across the grid cells of the range the year's total runs 1,607 mm to 3,562 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 2,627 mm, is the year's rain at the top of the page; the 2,458 mm here is the median year's, the twelve monthly medians added, which the rain rule reads. Habitat calendar, northern hemisphere; median year across the grid cells of the range, CHELSA.
Light
Open sky over the habitat: 26 to 31 mol/m²/day across the year (daily light integral, median year across the grid cells of the range, CHELSA; the lowest 10th-percentile month across the cells is 22, the highest 90th-percentile month 37).
Warmth and air
Monthly means: the coldest month's mean nightly low 11.1 °C in July (across the grid cells of the range 7.5 °C to 15.9 °C), the warmest month's mean daily high 19.8 °C in August (median year across the grid cells of the range, CHELSA). Cold floor: none read. The nearest figure is 11.1 °C, the coldest month's mean nightly low, July, in the median year (CHELSA); a month's mean of its nightly lows is warmer than the nights a floor is read from. The daily extremes were read at a weather cell whose ground is too far above or below the typical spot to correct for, and are not used.
Relative humidity at the habitat: 67 to 72% across the year (monthly means, median year across the grid cells of the range, CHELSA). A figure about the air, saying nothing about how the plant takes water.
How this section is made
Each card states this species' habitat figures with their sources, and what two fixed rules read from them; nothing here says what the plant does, wants or tolerates. The rules · the terms.
Seasons. Read from the median year of CHELSA monthly rainfall and mean temperature across the grid cells of the range: 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 moves 4 °C or more and the habitat lies 10° or more from the equator. A reading of the curves, not an observation of the plant.
Rain. CHELSA monthly precipitation, median year across the grid cells of the range. The rain that falls where the species is recorded; nothing about how the plant takes water.
Light. 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. CHELSA monthly means, median year across the grid cells of the range. No cold floor is read without a daily extremes series; the coldest month's mean nightly low named in its sentence is not one. Not a measured survival limit for any plant in a pot.
Humidity. CHELSA relative humidity, median year across the grid cells of the range.
Group. Listed under the genus Begonia in the archetype table, and Kew describes it as “subshrub or shrub”, “wet tropical”. A group is taken only where Kew's description of the species agrees with the table's listing. The table gives no figure and no prose; the cold floor is the habitat's alone.
Climate across the habitat
Habitat months, northern hemisphere
Mean daily high from 19 °C in Jan, Feb, Apr, May, Jun, Jul, Oct, Nov and Dec to 20 °C in Mar, Aug and Sep; mean nightly low from 11 °C in Jan, Jun, Jul, Aug and Sep to 12 °C in Feb, Mar, Apr, May, Oct, Nov and Dec. The cold quarter, Jun to Aug, is the three months around the coldest month's mean nightly low, around the first of the 5 months that tie for it. 2,458 mm of rain in the median year (the twelve monthly medians added), the wettest month Apr. The bands show the 10th to 90th percentile across 121 habitat cells. Beneath: daily light integral and relative humidity through the year, each on its own scale.

The daily extremes were not used: the correction for elevation, +1052 m, is beyond the 1,000 m either way that a lapse rate is applied over, so the weather cell's ground is other terrain than the typical spot's. So no cold floor is read for this species, and the coldest month's mean nightly low is not taken as one. What that cell gave, so corrected, over 44 years: absolute minimum 5.7 °C, 1st-percentile night 7.4 °C.
