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 72 observations

Condition 5th percentile Median 95th percentile
Coldest month, mean daily low 8.7 °C 11.0 °C 13.0 °C
Warmest month, mean daily high 27.3 °C 31.5 °C 31.9 °C
Annual rainfall 1,557 mm 1,644 mm 1,929 mm
Rainfall in the driest quarter 181 mm 245 mm 387 mm

It is barely found anywhere that freezes. This is not care advice and it is not a forecast. It is a measurement: we sampled the climate at every one of the 72 research-grade observations of Ludwigia sericea 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 Reading one as the other would place a plant several zones too warm, so we do not publish a hardiness zone, because we do not have one.
