We have a problem here at the moment in that it's been too warm for the leaves to drop off the trees, so we can't actually see where it is..... although I do know where there is some, 120 miles from me and about 30ft up in a tree which is neither oak nor apple.....If you want to see if you can grow some, try nicking a bit out of the bark of a fruit or oak tree, at the junction of two limbs where they form the V (Spaw, you should try to control those urges....). Stick the berries in that nick and with a lot of luck, something might grow. It gets there in nature because birds take a berry, find it tastes horrid, so wipe their beaks off in a suitable crevice (SPAW!! You've been told!), the beak scrapes a bit of the bark off and exposes the living cells just underneath. The mistletoe berries are very sticky and attach themselves to this layer, where they proceed to suck up the juices like the good little parasites they are!
Alternatively, the mistletoe is on the end of the mistlefoot.
