Why some famous flowers aren't here

A flower earns a page in a region only when there are enough dated, expert-checked reports there to show a real rhythm — start, peak, and fade. Where the reports are thin, we would be guessing, so we leave it out until the reports catch up. Based on reports from iNaturalist naturalists.
