Summary
Selenicereus anthonyanus is a cactus species native to southern Mexico. It is grown as an ornamental because of its nocturnal flowers and unusual, leaf-like stems. Common names include fishbone cactus, rickrack cactus, zig-zag cactus and St. Anthony's rickrack, and is sometimes referred to as an orchid cactus.

About the genus · Selenicereus
Selenicereus, from Ancient Greek σελήνη (selḗnē), meaning "moon", and Latin cēreus, meaning "candle", sometimes known as moonlight cactus, is a genus of epiphytic, lithophytic, and terrestrial cacti, found in Mexico, Central America, the Caribbean and northern South America. The term night-blooming cereus is also sometimes used, but this is also used for many night-blooming cacti, including Epiphyllum and Peniocereus. In 2017, the genus Hylocereus was brought into synonymy with Selenicereus. More on Wikipedia ›

Cultivation
Grouped as a other epiphyte by the genus Selenicereus, which is reliably one kind of plant (archetype table). The table supplies one figure for this group, a conventional minimum for the cold floor, and no prose.
Its year Rain rule: a summer growing season, June to October in the northern hemisphere (June to October at the habitat, northern).
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 (1287 mm of 1797 mm) falls in June to October, warmer than the year (wet-season mean 21.6 °C against a yearly mean of 20.5 °C). Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: December to April.
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 1797 mm a year, wettest June at 302 mm, driest February at 53 mm (habitat calendar, northern hemisphere).
This species’ habitat figures, with their source.
1797 mm a year at the habitat, 1287 mm of it June to October. Wettest month June at 302 mm, driest February at 53 mm. Across the envelope cells the year's total runs 1092 mm to 2688 mm (10th to 90th percentile of each cell's own year) (median year across the envelope cells, CHELSA; habitat calendar, northern 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: 25 to 40 mol/m²/day.
This species’ habitat figures, with their source.
Open sky over the habitat: 25 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 23, the highest 90th-percentile month 44).
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.
Warmth and air Cold floor 10 °C (archetype minimum for a other epiphyte, above the 6.7 °C habitat night).
This species’ habitat figures, with their source.
Coldest: the 1st-percentile night over 44 years at the typical cell is 6.7 °C, the absolute minimum -1.5 °C, 2 frost nights in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 36.7 °C. Monthly means: coldest night 12.7 °C in January (across the envelope cells 10.3 °C to 17.3 °C), warmest day 28.2 °C in April (median year across the envelope cells, CHELSA). Cold floor: 10 °C. The habitat figure, the 1st-percentile night over 44 years at the typical cell (NASA POWER), is 6.7 °C; the archetype table's conventional minimum for a other epiphyte (grouped by the genus Selenicereus, which is reliably one kind of plant) is 10 °C, which is higher, and the floor rule takes the higher.
NASA POWER daily minima and maxima 1981–2024 at the typical cell, lapse-corrected to its elevation; CHELSA monthly means, median year across the envelope cells, CHELSA. The cold floor is the figure named in its sentence, and the archetype table's group minimum where that is higher. Not a measured survival limit for any plant in a pot.
Relative humidity at the habitat: 61 to 68% across the year (monthly means, median year across the envelope cells, CHELSA). A figure about the air, saying nothing about how the plant takes water.

Each figure is the median across the 19 grid cells holding the 20 in-range records, with the 10th–90th percentile span across those cells after the slash where it differs. Extremes and elevation were read at the typical cell 1411:1662 (19.425, -96.875). Over 44 years there: absolute minimum -1.5 °C, 1st-percentile night 6.7 °C, 99th-percentile day 36.7 °C. Normals: CHELSA V2.1 1981–2010 climatology, 0.05° cells (each the mean of ~36 1 km pixels). Envelope: median and 10th–90th percentile of each month across the 19 distinct grid cells holding the 20 in-range records; extremes and elevation at the typical cell 1411:1662 (its coldest month's mean night nearest the median across cells); its position is the cell centre.
