orchidsociety.org
Almost every orchid society in existence is already a .org, because they’re membership nonprofits. This is the plain unqualified version of that name on the correct extension, which is about as clean a match as this market produces.
Orchid societies are among the best organised hobbyist networks anywhere: local chapters, formal judging, plant registries, and a global community trading divisions, flasks and expertise continuously. Some have been running since the nineteenth century.
The name suits a national or international body, a federation of local chapters, a shows and judging platform, a registry, or an educational resource. For an existing society operating under a longer regional name, it’s the natural umbrella address.
The commercial layer is real underneath. Growers, nurseries and supply retailers sell into this audience constantly, and community sites are where they reach them.
Exact match, correct extension, no hyphen.
The name is listed for sale. Offers welcome.
