WFO wfo-0001123840 Accepted WFO 2026-06 8 photographs CC BY

Plate 1 figs. a–h · 7 observations

This species has been photographed under an open licence only 7 times, so some figures below are different views of the same plant, taken on the same day, rather than different individuals. They are usually different parts of it: the leaf, the flower, the bark.

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 162 observations

Condition 5th percentile Median 95th percentile
Coldest month, mean daily low 1.1 °C 2.8 °C 11.7 °C
Warmest month, mean daily high 18.5 °C 21.6 °C 29.8 °C
Annual rainfall 2,109 mm 3,575 mm 5,030 mm
Rainfall in the driest quarter 117 mm 337 mm 775 mm

It is found where winters are cool but frost is light or absent. This is not care advice and it is not a forecast. It is a measurement: we sampled the climate at every one of the 162 research-grade observations of Lycopodiastrum casuarinoides 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 Reading one as the other would place a plant several zones too warm, so we do not publish a hardiness zone, because we do not have one.
