A living reference.
A documented starting point.
Taxonomy changes as plants are studied. This directory preserves the accepted names and synonym relationships in a specific World Flora Online release, so you can trace every entry to its source.
View the June 2026 source datasetWhat is included?
All 347,476 accepted species classified under Angiosperms in this snapshot, plus 710,971 names treated as synonyms of those species. Flowering trees, grasses, and other less familiar flowering plants belong here too.
Is this every flower that has ever existed?
No complete list of every historical or undiscovered species exists. This collection excludes unresolved names, subspecies and varieties as separate records, non-flowering plants, and most cultivated forms. It is not a complete fossil or cultivar register.
Can I order these flowers?
A botanical record does not establish cut-flower availability or suitability for an arrangement. Our 1230 florist guides cover commercial flowers, specialty garden cuts, and foliage, with design notes, photos, and calculator links. Calculator selection uses that florist collection; other ingredients can be entered as custom items.
