Summary
Fouquieria burragei, known commonly as the gulf ocotillo or pichilingue, is a species of perennial plant in the genus Fouquieria (referred to as ocotillos), native to the gulf coast of Baja California Sur. It is a shrub to small tree distinguished by its white to rose-red flowers, which are unique among the ocotillo species on the peninsula. It is the only ocotillo endemic to the peninsula, and is threatened by invasive species (particularly feral goats), tourism, coastal development and other human activities.

About the genus · Fouquieria
Fouquieria is a genus of 11 species of desert flowering plants, the sole genus in the family Fouquieriaceae. The genus is native to North America and includes the ocotillo and the Boojum tree or cirio. They have semi succulent stems with thinner spikes projecting from them, with leaves on the bases of the spikes. More on Wikipedia ›

Cultivation
Seasons
The rain rule reads a summer growing season: 70% of the median year's rain (144 mm of 194 mm) falls in January and July to September, warmer than the year (wet-season mean 26.2 °C against a yearly mean of 23.7 °C). Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: January to March and July.
Rain
194 mm in the median year at the habitat, 144 mm of it January and July to September. Wettest month September at 61 mm, driest month May at 0 mm; 4 months under 5 mm. Across the grid cells of the range the year's total runs 168 mm to 226 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 190 mm, is the year's rain at the top of the page; the 194 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 52 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 25, the highest 90th-percentile month 52).
Warmth and air
Coldest: the 1st-percentile night over 44 years at a typical spot in the range is 12.4 °C, the absolute minimum 8.5 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 38.4 °C. Monthly means: the coldest month's mean nightly low 15.3 °C in January (across the grid cells of the range 12.1 °C to 18.6 °C), the warmest month's mean daily high 33.0 °C in August (median year across the grid cells of the range, CHELSA). Cold floor: 12.4 °C, which is the 1st-percentile night over 44 years at a typical spot in the range (NASA POWER).
Relative humidity at the habitat: 50 to 57% 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 -114 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 22 °C in Jan and Dec to 33 °C in Jul and Aug; mean nightly low from 15 °C in Jan to 27 °C in Aug. The cold quarter, Dec to Feb, is the three months around the coldest month's mean nightly low. 194 mm of rain in the median year (the twelve monthly medians added), the wettest month Sep. The bands show the 10th to 90th percentile across 28 habitat cells. Over 44 years at a typical spot in the range (NASA POWER) the absolute minimum was 8.5 °C and the 99th-percentile day 38.4 °C; neither is dated to a month. Beneath: daily light integral and relative humidity through the year, each on its own scale.
