Where it actually grows measured, from 167 observations
| Condition | 5th percentile | Median | 95th percentile |
|---|---|---|---|
| Coldest month, mean daily low | 13.7 °C | 19.7 °C | 24.2 °C |
| Warmest month, mean daily high | 25.7 °C | 29.2 °C | 33.2 °C |
| Annual rainfall | 1,003 mm | 2,124 mm | 3,629 mm |
| Rainfall in the driest quarter | 9 mm | 120 mm | 509 mm |
It is not found anywhere that gets close to freezing. This is not care advice and it is not a forecast. It is a measurement: we sampled the climate at every one of the 167 research-grade observations of Ipomoea mauritiana 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 Reading one as the other would place a plant several zones too warm, so we do not publish a hardiness zone, because we do not have one.
