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 489 observations

Condition 5th percentile Median 95th percentile
Coldest month, mean daily low 3.6 °C 10.7 °C 16.8 °C
Warmest month, mean daily high 22.7 °C 26.7 °C 36.8 °C
Annual rainfall 118 mm 483 mm 1,141 mm
Rainfall in the driest quarter 2 mm 15 mm 185 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 489 research-grade observations of Arthrocaulon macrostachyum 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 Reading one as the other would place a plant several zones too warm, so we do not publish a hardiness zone, because we do not have one.
