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 5 botanical countries

Native distribution of Rubus conduplicatus, 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
China South-Central	CHC	ASIA-TEMPERATE
China Southeast	CHS
Japan	JAP
Taiwan	TAI
Vietnam	VIE	ASIA-TROPICAL

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 349 observations

Condition	5th percentile	Median	95th percentile
Coldest month, mean daily low	-0.5 °C	2.7 °C	11.6 °C
Warmest month, mean daily high	17.8 °C	21.0 °C	29.4 °C
Annual rainfall	2,418 mm	3,197 mm	4,582 mm
Rainfall in the driest quarter	156 mm	252 mm	411 mm

It is found where winters bring light 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 349 research-grade observations of Rubus conduplicatus 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 Reading one as the other would place a plant several zones too warm, so we do not publish a hardiness zone, because we do not have one.
