This is not a rose question or comment but does anyone know if European mistletoe, Viscum album, will grow on Eucalyptus?

I don't know what sort of mistletoe we have in Western Australia, but the 1973 book 'Flowers and Plants of Western Australia' R. Erickson, Marchant & Morcombe says on p198.
Misletoes are parasitic and are often seen on wattles, eucalypts, sheoaks, kurrajongs and Grevilleas. Over 20 species in 5 genera occur in W.A., two of them shown in plates 462 (Amyema fitzgeraldii) and 519 (Lysiana casuarinae)

We have a mistletoe (unknown) here which grows on rhododendrons, but not on the neighboring karri trees, Eucalyptus diversicolour, which drop their bark.

One year I planted seeds of the superb yellow flowered mistletoe tree, Nuytsia floribunda, (locally known as the Christmas Tree) in a sandy area in the bush and put some hosting couch grass in the hole as well. Unfortunately they never germinated.

Thank you Patricia, in the U.K. I have seen Viscum album growing on many types of tree, but never oak, conifers or Eucalyptus. A lady in the village has a big Eucalyptus gunnii in her garden and she asked me this morning about growing mistletoe on it.

The internet tells me Eucalyptus gunnii sheds its bark annually. I theeeenk the mistletoe would fall off with the bark.

Yes you're definitely right, it could never get a toe-hold on a tree with exfoliating bark.

Don't know about that - most Eucalypts exfoliate, and there are plenty of local mistletoes that have evolved to hang in. The mistletoe bird Dicaeum hirundinaceum, as brightly-coloured as a robin, eats and spreads the seeds: it does a little defaecation dance sideways on a branch , which makes sure ingested seeds land where they can attach.

Yes, as you say the endemic flora has evolved together, I'm sure a European mistletoe couldn't get a purchase. Do you have a plant called a Love Vine, Cassytha in your area? It's like a giant tropical sort of dodder. I find these types of plant fascinating, do you get broomrapes too?

Cassythia grows in the eastern states and SE South Australia, but hasn't reached this far.
One of the broomrapes is a declared weed in Australia, with the potential for causing serious crop losses. Not in SA yet.
