How this list was compiled: Written for this site; nothing was copied from another list. Questions and wrong choices are our own. Each explanation restates, in our own sentences, facts from the page named and linked beside it. Each answer was checked on 2026-10-02 against that page, fetched that day: the article of the English Wikipedia (https://en.wikipedia.org, text under the CC BY-SA 4.0 license) on the flower, the plant part or the custom asked about. A state flower or national flower is asked only where the article on that flower states it. Left out on purpose: birth-month flowers (no page we could fetch lists them with a source), what a flower is said to mean to a sweetheart, remedies and anything about health, prices, and records that change. Dropped after checking: questions whose fact another quiz on this site already asks, such as the tulip and the turban, saffron and the crocus, tea and the camellia, the skunk cabbage that melts ice, Lei Day, the golden wattle of Australia, vanilla and the orchid, the bracts of the poinsettia and the dogwood, and the state flowers of Texas, Alaska, Michigan, Kansas and Arizona. Levels are our estimate: easy is fair for any table, medium suits a gardener, hard will stump most of them. Each round is stored easiest first, and each question carries the date its page was read.
