I wrote about the QOSF in the other dragon fruit thread about a year ago. Sven Merten (sp?) took several cuttings to Florida some years ago and he did some research as to the synonyms. Some are pretty obvious base don looking at Pine Island's pages. Physican Graffiti is 1-S, Cosmic Charlie is 2-S, Purple Haze = 5-S, Voodoo Child is 8-S (but not 100% certain on this one), Dark Star (aka Arizona Red) = 9-S, American Beauty = QOSF, Bloody Mary = Ben Poirier Polyrhizus.

You need one more undatus. Leo says 'Orton', named for the late Orton Englehart, inventor of the impact (Rainbird) sprinkler, is his favorite undatus. That's despite Leo's close friendship with Paul. I'm giving it a try.
