LA should add an option so folks could see what was on a wanted list. I expect a lot time someone might want to just divide a clump and only have enough extra for one or two people, but not enough to list on the LA. Or see something someone wanted and was simply willing to arrange to sell it without being a big vendor, though it seems likely the bigger vendors would be the most likely to have something tucked back growing somewhere. I expect bigger vendors operate much like most retail places and concentrate on higher demand cultivars, but they could still have older ones growing here and there.
