I recently discovered this unregistered PCI iris, being sold by Sequim Rare Plants.
http://sequimrareplants.com/Ir... After I ordered it, I did another search and discovered a different nursery *also* selling a PCI with the name "Silver Moon", but their image and description differs from that of the first nursery.
http://www.yerbabuenanursery.c... A third nursery also carries a PCI "Silver Moon"; their image and description appears to match that of the second nursery.

So it looks like there are (at least) two different PCIs in commerce going under the (unregistered with the AIS) name of "Silver Moon".
