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.

Peak flowering in Jun. Each bar is the share of Gaillardia aristata observations in which someone actually recorded the reproductive state and found the plant in flower, not the raw number of flowering records. That distinction matters: people observe plants far more in spring than in winter, so a bare count of flowering records partly measures when people go outside. Dividing by the number examined removes that. 1,756 of 1,929 examined observations were in flower, every one of them research grade. The whisker on each bar is a 95% Wilson interval. 3 months have fewer than 5 examined observations, so no proportion is drawn for them. This is still a global aggregate and not a forecast for your garden: the same species flowers on different dates in different hemispheres. Where a species has fewer than 30 flowering records we do not draw this chart at all. Computed from 10.15468/dl.cgje2x.

When it blooms, where you are 2 states

Peak flowering moves by 2 months across these states. A national average would be the wrong answer to a local question, so each of these is computed only from observations made in that state.

Where it actually grows measured, from 1,981 observations

Condition 5th percentile Median 95th percentile
Coldest month, mean daily low -18.8 °C -11.1 °C -4.8 °C
Warmest month, mean daily high 20.8 °C 24.8 °C 29.2 °C
Annual rainfall 332 mm 473 mm 993 mm
Rainfall in the driest quarter 33 mm 60 mm 160 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 1,981 research-grade observations of Gaillardia aristata 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. Climate from CHELSA V2.1 (Karger et al. 2017); occurrences from 10.15468/dl.cgje2x.

Named cultivars 1 recorded

Selections of Gaillardia aristata 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.
