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.

The sheet
View the digitised specimen (CC BY 4.0)

A real pressed plant, in a real collection, under the accession number above. Not an illustration of one. The holding institution does not serve this sheet’s image to third parties, so there is no photograph here. The record is real and the link goes to it. Where we hold no openly licensed sheet for a species this section is simply absent, and where a sheet never recorded who determined it, that field stays empty rather than being filled in. Roughly half of all herbarium sheets never recorded a determiner, which is ordinary.

Where it actually grows measured, from 584 observations

Condition 5th percentile Median 95th percentile
Coldest month, mean daily low -12.1 °C -4.1 °C 9.8 °C
Warmest month, mean daily high 22.9 °C 28.2 °C 35.1 °C
Annual rainfall 400 mm 716 mm 1,688 mm
Rainfall in the driest quarter 10 mm 84 mm 247 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 584 research-grade observations of Platycladus orientalis 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 Reading one as the other would place a plant several zones too warm, so we do not publish a hardiness zone, because we do not have one.

Named cultivars 3 recorded

Selections of Platycladus orientalis that somebody named and propagated. A cultivar is not a botanical taxon: it is governed by the cultivated-plant code rather than the botanical one, so it appears in no taxonomic backbone, and it has no native range and no wild population of its own. These get no page here, because a cultivar has no photographs, no range and no flowering data of its own, and a page with none of those is not a page.

From Wikidata (CC0), joined to this species on its World Flora Online identifier, so the link to the parent is exact rather than a name match. This list is what is recorded in an openly licensed register; it is not every cultivar that exists, and for many genera it is not close. Why, and how far short it falls.
