Uli, If you can't find the listing you're looking for (and it may be out of date by now anyway), IMO the next best thing is the listing Jim Shields has <http://www.shieldsgardens.com/BulbSources.html>. It's the most complete one I know of and is readily accessible on the Internet. Plus, he adds and updates it regularly if you send him the information. (For example, he could add the Archibalds new website, especially now that they finally activated the online ordering.) Good luck, --Lee Poulsen Pasadena area, California, USDA Zone 9-10 >Dear All, > > >Some time ago there was a list of practically all bulb nurseries of the world >edited by the IBS but I cannot find any reference.
