About the genus · Vaccinium
Vaccinium is a common and widespread genus of shrubs or dwarf shrubs in the heath family (Ericaceae). The fruits of many species are eaten by humans and some are of commercial importance, including the cranberry, blueberry, bilberry (whortleberry), lingonberry (cowberry), and huckleberry. Like many other heath plants, they are restricted to acidic soils.

Cultivation
Seasons
The rain rule reads a sharp season: 70% of the median year's rain (2,085 mm of 2,875 mm) falls in May to October. The temperature curve is flat, 2.2 °C between the warmest and coldest month, so the growing-season rule does not infer a growing season from it. Months are the habitat's, northern hemisphere. The temperature curve moves under 4 °C between the warmest and coldest month, where the shift rule does not apply, so they are not shifted for a collection elsewhere.
Rain
2,875 mm in the median year at the habitat, 2,085 mm of it May to October. Wettest month August at 410 mm, driest month February at 92 mm. Across the grid cells of the range the year's total runs 2,801 mm to 3,847 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 3,332 mm, is the year's rain at the top of the page; the 2,875 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 38 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 24, the highest 90th-percentile month 41).
Warmth and air
Coldest: the 1st-percentile night over 44 years at a typical spot in the range is 9.3 °C, the absolute minimum 4.8 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 29.5 °C. Monthly means: the coldest month's mean nightly low 13.9 °C in January (across the grid cells of the range 11.3 °C to 15.8 °C), the warmest month's mean daily high 23.4 °C in April (median year across the grid cells of the range, CHELSA). Cold floor: 9.3 °C, which is the 1st-percentile night over 44 years at a typical spot in the range (NASA POWER).
Relative humidity at the habitat: 64 to 70% 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. NASA POWER daily minima and maxima over 44 years at a typical spot in the range, lapse-corrected +658 m to its elevation; CHELSA monthly means, median year across the grid cells of the range. The cold floor is the 1st-percentile night named in its sentence. Not a measured survival limit for any plant in a pot.
Humidity. CHELSA relative humidity, median year across the grid cells of the range.
Climate across the habitat
From few records: this habitat climate is read from 8 records in 4 grid cells; a page says so under 12 records or 5 cells, and shows the figures as read.
Habitat months, northern hemisphere
Mean daily high from 21 °C in Jan and Dec to 23 °C in Mar, Apr, May, Jun, Sep and Oct; mean nightly low from 14 °C in Jan and Feb to 17 °C in May, Jun and Jul. The cold quarter, Dec to Feb, is the three months around the coldest month's mean nightly low, centred on the 2 months in a row that tie for it. 2,875 mm of rain in the median year (the twelve monthly medians added), the wettest month Aug. The bands show the 10th to 90th percentile across 4 habitat cells. Over 44 years at a typical spot in the range (NASA POWER) the absolute minimum was 4.8 °C and the 99th-percentile day 29.5 °C; neither is dated to a month. Beneath: daily light integral and relative humidity through the year, each on its own scale.
