field: care

reason: Not published anywhere on this site. Every care claim we could make cheaply would be an unsourced enum, which is what the previous version of this site did and why it was deleted.

field: toxicity

reason: Not published. The widely copied list is a copyrighted compilation restricted to noncommercial use, and we will not scrape it. A sourced toxicity dataset is being built from primary literature and is not ready.

reason: No page on this site has been reviewed by a named botanist. The determination label says so, on every page.

reason: No vernacular name for this taxon in Wikidata (P1843) or iNaturalist. We do not invent one, and we do not present the scientific name as though it were a common name.

reason: Not published for any species. A USDA hardiness zone is the average annual EXTREME minimum temperature, and we hold the mean daily minimum of the coldest month, which is a different quantity and typically about 16 C warmer. Presenting one as the other would place a plant several zones too warm, so we do not publish a zone at all.

field: phenology

reason: Only 0 annotated flowering records, below our threshold of 30. A curve fitted to a dozen records is noise, so we do not draw one.

A USDA hardiness zone is the average annual EXTREME minimum temperature, and we hold the mean daily minimum of the coldest month, which is a different quantity and typically about 16 C warmer.

authors: Buckley

published_in: Proc. Acad. Nat. Sci. Philadelphia 1861 (1862) 454

reason: Fewer than 30 georeferenced research-grade observations of this taxon, which is too few to state a percentile range for the conditions it grows in. We would rather show nothing than a range computed from eight points in one county.

reason: No vernacular name for this taxon in Wikidata (P1843) or iNaturalist. We do not invent one, and we do not present the scientific name as though it were a common name.

reason: Only 0 annotated flowering records, below our threshold of 30. A curve fitted to a dozen records is noise, so we do not draw one.
