Mike, the bagged ones I've bought have been from the E. society members, at shows. They do have some interesting selections, but the quality of the cuttings isn't that great. I find it sad that they would discourage people from growing them by selling inferior cuttings. Paying $10-$15 for a four" or five " cutting that isn't from mature leaves is not encouraging new growers. The last one I bought a year ago is still in a 2 1/2" pot and just now starting to get a couple of new growths. I've got to wonder if I'll live long enough to see it bloom.
If there is no buyers market, what are you going to do with all those duplicates? When I trim mine the cuttings just go in the trash, unless someone else has asked for it. Of course, in my neighborhood, any thing that goes in the dumpster is fair game. I see my Rose 'Taboo' all over the park and the cutting grown ones look better that my grafted one.
Same with my pink Plumeria. I really should put tags on them before throwing them away. NOT!
