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 1,377 observations

Condition	5th percentile	Median	95th percentile
Coldest month, mean daily low	-14.9 °C	-8.7 °C	-1.4 °C
Warmest month, mean daily high	18.7 °C	21.8 °C	23.6 °C
Annual rainfall	582 mm	711 mm	1,264 mm
Rainfall in the driest quarter	93 mm	113 mm	237 mm

It is found where winters bring hard frost. This is not care advice and it is not a forecast. It is a measurement: we sampled the climate at every one of the 1,377 research-grade observations of Rhodobryum roseum 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 Reading one as the other would place a plant several zones too warm, so we do not publish a hardiness zone, because we do not have one.
