Summary
Echinopsis albispinosa is a species of cactus from Argentina. Although Echinopsis sylvestrii is a synonym of this species, it should not be confused with Chamaecereus silvestrii, which has a very different appearance.

About the genus · Echinopsis
Echinopsis is a genus of cacti native to South America, sometimes known as hedgehog cactus, sea-urchin cactus or Easter lily cactus. As of November 2025, Plants of the World Online used a broad circumscription of the genus, resulting in about 80 accepted species, ranging from large and treelike types to small globose cacti. The name derives from echinos hedgehog or sea urchin, and opsis appearance, a reference to these plants' dense coverings of spines.

Cultivation
Grouped as a cactus or succulent, listed under the genus Echinopsis in the archetype table, and Kew describes it as “succulent subshrub”.
Seasons
The rain rule reads a summer growing season: 70% of the median year's rain (392 mm of 496 mm) falls in December to March, warmer than the year (wet-season mean 20.0 °C against a yearly mean of 16.8 °C). Months are the habitat's, southern hemisphere; shifted six months for a northern-hemisphere collection: June to September.
Rain
496 mm in the median year at the habitat, 392 mm of it December to March. Wettest month January at 127 mm, driest months (3 at 3 mm); 3 months under 5 mm. Across the grid cells of the range the year's total runs 458 mm to 869 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 496 mm, is the year's rain at the top of the page; the 496 mm here is the median year's, the twelve monthly medians added, which the rain rule reads. Habitat calendar, southern hemisphere; median year across the grid cells of the range, CHELSA.
Light
Open sky over the habitat: 25 to 42 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 21, the highest 90th-percentile month 42).
Warmth and air
Coldest: the 1st-percentile night over 44 years at a typical spot in the range is -0.5 °C, the absolute minimum -8.1 °C, 227 frost nights in 44 years, 5.2 a year (NASA POWER daily minima). Warmest: the 99th-percentile day is 34.6 °C. Monthly means: the coldest month's mean nightly low 5.6 °C in July (across the grid cells of the range 3.6 °C to 7.5 °C), the warmest month's mean daily high 25.0 °C in December (median year across the grid cells of the range, CHELSA). Cold floor: -0.5 °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 65% 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 -442 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.
Group. Listed under the genus Echinopsis in the archetype table, and Kew describes it as “succulent subshrub”. 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
From few records: this habitat climate is read from 3 records in 3 grid cells; a page says so under 12 records or 5 cells, and shows the figures as read.
Habitat months, southern hemisphere
Mean daily high from 19 °C in Jun and Jul to 25 °C in Jan, Nov and Dec; mean nightly low from 6 °C in Jul to 16 °C in Jan, Feb and Dec. The cold quarter, Jun to Aug, is the three months around the coldest month's mean nightly low. 496 mm of rain in the median year (the twelve monthly medians added), the wettest month Jan. The bands show the 10th to 90th percentile across 3 habitat cells. Over 44 years at a typical spot in the range (NASA POWER) the absolute minimum was -8.1 °C and the 99th-percentile day 34.6 °C; neither is dated to a month. Beneath: daily light integral and relative humidity through the year, each on its own scale.
