Every figure is a research-grade observation under CC0, CC BY or CC BY-SA, rehosted with the photographer’s name, the licence and the observation it came from. Photographs under a NonCommercial licence are excluded from this site and are never stored, which costs us a great many pictures and is not negotiable.

Where it actually grows measured, from 60 observations

Condition 5th percentile Median 95th percentile
Coldest month, mean daily low 0.0 °C 4.8 °C 9.3 °C
Warmest month, mean daily high 16.6 °C 18.8 °C 21.3 °C
Annual rainfall 835 mm 1,510 mm 3,197 mm
Rainfall in the driest quarter 173 mm 282 mm 617 mm

It is found where winters are cool but frost is light or absent. This is not care advice and it is not a forecast. It is a measurement: we sampled the climate at every one of the 60 research-grade observations of Achrophyllum quadrifarium that carry a coordinate, and this is the range those places actually span. The 5th and 95th percentiles are used rather than the minimum and maximum, because a single cultivated specimen in a heated conservatory should not widen a tropical plant's range to the Arctic.

This is not a hardiness zone. A USDA zone is the average annual extreme minimum temperature. The figure above is the mean daily minimum of the coldest month, which is a different quantity and is typically far warmer. Reading one as the other would place a plant several zones too warm, so we do not publish a hardiness zone, because we do not have one.
