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: 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 Presenting one as the other would place a plant several zones too warm, so we do not publish a zone at all.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 7 annotated flowering records, below our threshold of 30. A curve fitted to a dozen records is noise, so we do not draw one.

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: 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 Presenting one as the other would place a plant several zones too warm, so we do not publish a zone at all.
