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.

Native range 10 botanical countries

Native distribution of Callianthe pauciflora, after Kew’s World Checklist of Vascular Plants. Introduced, extinct and doubtful records are excluded, so this is where the plant is from, not everywhere it now grows.

Region	TDWG code	Continent
Argentina Northeast	AGE	SOUTHERN AMERICA
Argentina Northwest	AGW
Bolivia	BOL
Brazil Northeast	BZE
Brazil South	BZS
Brazil Southeast	BZL
Brazil West-Central	BZC
Paraguay	PAR

Region boundaries approximated from Natural Earth (public domain) and mapped to TDWG World Geographical Scheme for Recording Plant Distributions (WGSRPD) level-3 botanical countries (Brummitt 2001). Indicative, not the official WGSRPD geometry.

Where it actually grows measured, from 240 observations

Condition	5th percentile	Median	95th percentile
Coldest month, mean daily low	3.7 °C	8.1 °C	12.2 °C
Warmest month, mean daily high	25.5 °C	30.2 °C	31.8 °C
Annual rainfall	905 mm	1,118 mm	1,615 mm
Rainfall in the driest quarter	30 mm	95 mm	305 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 240 research-grade observations of Callianthe pauciflora 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 Reading one as the other would place a plant several zones too warm, so we do not publish a hardiness zone, because we do not have one.
