Cheeky Dan![]()
Actually Gordonvale is still excised from the World Heritage Area, and (I think) the national park. So rhodies suddenly become okay![]()
There's also a big old walnut tree there ... and the odd post with a bit of rail nearby,
cheers

And deadly nightshade is a pretty plant too. A friend worked for the forestry in scotland and I knew never to bring the subject of rhodies up with him unless I wanted to listen to a hour long rant. Get rid of it all (my personal opinion).

There is such a thing?

A lot of plants do this Nik, even species of Eucalyptus. Its called allelopathy and its surprisingly common.Son of a Beach wrote:rhodos actually poison the soil to out compete other nearby plants.
Rhododendron are capable of selfing so one plant will do. In the British Isles the problem is not sexual reproduction (at least not for rhododendrons). There the plants sucker and rapidly form dense thickets.Son of a Beach wrote:Do they need another plant to reproduce? Many plants do not.
Rhododendron ponticum is the major invasive species in Britain - and incidentally it has purple flowers. It was introduced into the British Isles in the Victorian era. R. ponticum has been cultivated in this State for probably close too 100 years. Rhododendrons have not shown themselves to be invasive in Tasmania. I believe that there are a couple of species that have "naturalised" in small populations in the Dandenongs (VIC) and in the Blue Mountains (NSW), but I don't think these are considered as dangerous infestations. If they were spreading by suckering that would be a worry. Recent research (Dr Andrew Hingston, University of Tasmania, May 2006) has reported larger numbers of seedlings at locations in western Tasmania (I don't have specifics). It has been suggested that this can be attributed to the introduction of the bumblebee into Tasmania. So, it would appear that the jury is still out on this question.Son of a Beach wrote:They are a dangerously invasive plant.
Very sweeping statement. Rhododendron is a very diverse genus of plants ranging from tiny alpine ground covers to massive forest trees. It includes tropic epiphytes (vireyas) and the azaleas. There are two Australian native species, Rhododendron lochiae and Rhododendron viriosum (so hardly noxious weeds).Son of a Beach wrote:Yes, I would very much prefer to get rid of all the rhodo from the state (country!) completely. They should be treated as a noxious weed, in my opinion.

Launcestonians, for instance.
OOOOOpps. Sorry Nik, I forgot myself for a moment.
Sorry Bill, but I don't think this is true. I don't know of any examples of rhododendrons spreading or behaving like weeds anywhere in Tasmania. Other than the above mentioned study on bumblebees I can't find any references or suggestion that there might even be a possible problem in Tassie (and he was much more concerned with the bumblebees). If you know some where that rhododendrons have become a weed please let us know. As far as I know, R. ponticum has been cultivated in this State for a long time. I'm not aware of any evidence that R. ponticum or any other rhododendron behaves like a weed here. They don't get a mention on any official weed lists that I've seen. Without evidence it is a non issue - rhododendrons are not currently considered a weed in Tasmania.billshep wrote:If Ernie's rhodo was a ponticum it would probably have spread far and wide by now over the Vale
