Where it actually grows measured, from 651 observations
| Condition | 5th percentile | Median | 95th percentile |
|---|---|---|---|
| Coldest month, mean daily low | -16.3 °C | -11.6 °C | -4.0 °C |
| Warmest month, mean daily high | 19.7 °C | 24.3 °C | 27.5 °C |
| Annual rainfall | 690 mm | 1,013 mm | 1,484 mm |
| Rainfall in the driest quarter | 76 mm | 200 mm | 310 mm |
It is found where winters are severely cold. This is not care advice and it is not a forecast. It is a measurement: we sampled the climate at every one of the 651 research-grade observations of Botrychium matricariifolium 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 Reading one as the other would place a plant several zones too warm, so we do not publish a hardiness zone, because we do not have one.
