Summary

Veronica odora, known as the boxwood hebe, mountain-box, Hebe odora or Hebe buxifolia, is a plant in the family Plantaginaceae, and it is native to New Zealand. Veronica odora was discovered on the Auckland Islands by J.D Hooker in 1840. A certain amount of confusion later arose following its collection on mainland New Zealand by Ernst Dieffenbach and its naming as Veronica buxifolia by George Bentham. Even overseas, Veronica odora is still not infrequently known as Veronica buxifolia.

Each sentence is one card's own one-line form, written by the same rule as the card (Its year, Rain, Light, Temperature); the note cannot say what a card does not. Months are given for the northern hemisphere (set your site in Settings to change this), and the habitat's own alongside. The cards · the figures.

Cultivation

Its year Rain rule: no season, 70% of the rain takes 8 months (November to June in the northern hemisphere).

This species’ habitat figures, and what two fixed rules read from them.

The rain rule reads no season: 70% of the year's rain (1597 mm of 2251 mm) takes 8 months, May to December. Mean temperature moves 10.2 °C between the warmest and coldest month. Months are the habitat's, southern hemisphere; shifted six months for a northern-hemisphere collection: November to June.

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.

2251 mm a year at the habitat, 1597 mm of it May to December. Wettest month October at 224 mm, driest February at 139 mm. Across the envelope cells the year's total runs 1158 mm to 4579 mm (10th to 90th percentile of each cell's own year) (median year across the envelope cells, CHELSA; habitat calendar, southern hemisphere).

Light Open sky over the habitat: 9 to 39 mol/m²/day.

This species’ habitat figures, with their source.

Open sky over the habitat: 9 to 39 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 7, the highest 90th-percentile month 42).

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 -3.5 °C (1st-percentile habitat night, NASA POWER).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is -3.5 °C, the absolute minimum -6.7 °C, about 89 frost nights a year (NASA POWER daily minima). Warmest: the 99th-percentile day is 24.0 °C. Monthly means: coldest night -2.0 °C in July (across the envelope cells -5.2 °C to 2.2 °C), warmest day 15.6 °C in January (median year across the envelope cells, CHELSA). Cold floor: -3.5 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).
