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 212 observations

Condition 5th percentile Median 95th percentile
Coldest month, mean daily low -5.4 °C -1.0 °C 10.0 °C
Warmest month, mean daily high 10.8 °C 17.6 °C 25.2 °C
Annual rainfall 466 mm 1,315 mm 3,706 mm
Rainfall in the driest quarter 3 mm 126 mm 700 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 212 research-grade observations of Lathyrus magellanicus 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 Reading one as the other would place a plant several zones too warm, so we do not publish a hardiness zone, because we do not have one.
