About the genus · Asparagus
Asparagus or garden asparagus is a perennial flowering plant species in the genus Asparagus native to Eurasia. Widely cultivated as a vegetable crop, its young shoots are used as a spring vegetable. In 2024, world production of asparagus was 8.9 million tonnes, led by China with 87% of the total.

Cultivation
Seasons
The rain rule reads a summer growing season: 70% of the median year's rain (1,037 mm of 1,374 mm) falls in May to September, warmer than the year (wet-season mean 21.0 °C against a yearly mean of 11.9 °C). Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: November to March.
Rain
1,374 mm in the median year at the habitat, 1,037 mm of it May to September. Wettest month July at 304 mm, driest month December at 25 mm. Across the grid cells of the range the year's total runs 791 mm to 1,778 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 1,419 mm, is the year's rain at the top of the page; the 1,374 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: 15 to 37 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 12, the highest 90th-percentile month 38).
Warmth and air
Coldest: the 1st-percentile night over 44 years at a typical spot in the range is -11.6 °C, the absolute minimum -17.8 °C, 5,172 frost nights in 44 years, 117.5 a year (NASA POWER daily minima). Warmest: the 99th-percentile day is 31.9 °C. Monthly means: the coldest month's mean nightly low -6.5 °C in January (across the grid cells of the range -15.7 °C to 1.6 °C), the warmest month's mean daily high 26.7 °C in August (median year across the grid cells of the range, CHELSA). Cold floor: -11.6 °C, which is the 1st-percentile night over 44 years at a typical spot in the range (NASA POWER).
Relative humidity at the habitat: 55 to 69% 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 +60 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
Habitat months, northern hemisphere
Mean daily high from 2 °C in Jan to 27 °C in Aug; mean nightly low from -7 °C in Jan to 21 °C in Jul and Aug. The cold quarter, Dec to Feb, is the three months around the coldest month's mean nightly low. 1,374 mm of rain in the median year (the twelve monthly medians added), the wettest month Jul. The bands show the 10th to 90th percentile across 774 habitat cells. Over 44 years at a typical spot in the range (NASA POWER) the absolute minimum was -17.8 °C and the 99th-percentile day 31.9 °C; neither is dated to a month. Beneath: daily light integral and relative humidity through the year, each on its own scale.
