Where it actually grows measured, from 166 observations
| Condition | 5th percentile | Median | 95th percentile |
|---|---|---|---|
| Coldest month, mean daily low | -12.4 °C | -9.1 °C | -0.5 °C |
| Warmest month, mean daily high | 24.1 °C | 26.0 °C | 28.8 °C |
| Annual rainfall | 410 mm | 560 mm | 804 mm |
| Rainfall in the driest quarter | 82 mm | 101 mm | 157 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 166 research-grade observations of Sium sisarum 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 Reading one as the other would place a plant several zones too warm, so we do not publish a hardiness zone, because we do not have one.
