Well, fortunately -- or unfortunately, if you're an oak tree -- mistletoe is ubiquitous. Whomever came up with Clan Hay's badge got lucky. That said, aside from the fact that I can pick up fresh mistletoe at least once a year when it goes on sale in stores at Christmas, there's lots of plastic versions.
So I'm set, neener, neener. 
I would like a reproduction of the gold, green enamel and pearls brooch I saw illustrated in Moncrieffe's book, in the Hay section. Hadn't thought about that for years. Either as a cap badge or as a kilt pin it'd be a stunner.
Of course, I also have the silk dandelion -- reminder of the Passing of the Torch kilt night in Victoria.
