Summary

Stachys ajugoides is a species of flowering plant in the mint family known by the common name bugle hedgenettle. It is native to western North America, where it can be found in many types of habitat in Oregon, California, and Baja California, especially moist areas. It is an aromatic herb with serrate leaves. The inflorescence is a spike of interrupted clusters of flowers, often in shades of pink.

Cultivation

Seasons

The rain rule reads a winter growing season: 70% of the median year's rain (454 mm of 640 mm) falls in December to March, cooler than the year (wet-season mean 10.4 °C against a yearly mean of 14.3 °C). Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: June to September.

Rain

640 mm in the median year at the habitat, 454 mm of it December to March. Wettest month January at 126 mm, driest month July at 1 mm; 2 months under 5 mm. Across the grid cells of the range the year's total runs 342 mm to 1,307 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 634 mm, is the year's rain at the top of the page; the 640 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: 14 to 51 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 53).

Warmth and air
Temperature

Coldest: the 1st-percentile night over 44 years at a typical spot in the range is 2.2 °C, the absolute minimum -2.7 °C, 23 frost nights in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 33.5 °C. Monthly means: the coldest month's mean nightly low 5.5 °C in January (across the grid cells of the range -3.0 °C to 9.3 °C), the warmest month's mean daily high 26.1 °C in July (median year across the grid cells of the range, CHELSA). Cold floor: 2.2 °C, which is the 1st-percentile night over 44 years at a typical spot in the range (NASA POWER).

Humidity

Relative humidity at the habitat: 57 to 61% 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 +253 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.

How this section is made
Each figure is the median across the 189 grid cells holding the 284 in-range records, with the 10th–90th percentile span across those cells after the slash where it differs. A dash is a month one or more of those cells has no figure for in the grid (a variable CHELSA does not carry there), so no median is taken rather than one over fewer cells. Extremes and elevation were read at a typical spot in the range, cell 1148:1266 (32.575, -116.675). Over 44 years there: absolute minimum -2.7 °C, 1st-percentile night 2.2 °C, 99th-percentile day 33.5 °C. Normals: CHELSA V2.1 1981–2010 climatology, 0.05° cells (each the mean of ~36 1 km pixels). Across the range: median and 10th–90th percentile of each month across the 189 distinct grid cells holding 284 of the 284 in-range records; extremes and elevation at the typical cell 1148:1266 (its coldest month's mean nightly low nearest the median across cells); its position is the cell centre. Extremes: NASA POWER (MERRA-2) daily 1981–2024, cell 32.50_-116.875, lapse-corrected +253 m at 6.5 °C/km. Elevation: ETOPO 2022, 647 m (cell mean).

Natural habitat

Native range as published by WCVP; the marker is where the records are densest and decides nothing: the climate was read across the cells of the in-range records placed well enough to read one, not at the marker.
Openly licensed records inside the range, framed on where they fall.

Evidence usedThe map marker rests on all 429 georeferenced records inside the native range; the climate across the range on the 284 of them placed to within 10 km; the map shows only the 103 openly licensed ones, which alone would put the marker 50 km away. 145 in-range records are placed to worse than 10 km, or with no stated accuracy (admitted only as a person's observation to three decimals), and stay on the map but off the climate.
How this section is made
The map marker: the openly licensed record nearest the middle of the densest 1° population of the 429 in-range records; it decides nothing. Records outside the native range, living specimens and records marked introduced are not used; which records count.

Every source is recorded as having answered, reported nothing, refused, failed, not been asked, or answered twice where one answer is taken (“not taken: two items answered”), and, for a source asked when this page was built, when: the figures are as the source held them that day; a source read from a file (Kew's World Checklist, a GBIF download) says "as of" the file's day instead; a row carried from an earlier build of the page names that build instead. Only “nothing to report” is ever shown as an absence. Records came from 53 datasets via GBIF.org; each carries its own licence.
