Many years ago I saw this plants at Hadspen where it had completely taken over part of the garden. They had to clear the whole area to get rid of it as it is so invasive. Though very beautiful. I have also heard of it invading a house wall cavity where it appeared in the roof! So be warned.
This is my first posting so please excuse the nature of it. It is a plea for help. I do love this plant but unfortunately I think I need to kill it because it is seriously invading our house. It is entering under thick stone walls and passing under the plastic damp proof membrane below our flooring.
It first appeared sprouting from behind the skirting board about 15 feet into our house relative to the outside world. We tried Weedol and Roundup on it but it grew back just as vigorously.
More recently we noticed cracking and bulging of an internal plasterboarded wall extending up to ceiling height. I then broke open the plasterboard to discover that it was just on the point of invading the room above.
Clearly we will need to pull up the floor and DPM to dig it out and I think we really can't trust it not to invade us again so I suspect that we will need some serious excavation of our garden and its walls. (It has already gone beneath our 7 foot stone wall into our neighbour's garden)
Even if we do attempt to remove all its root system I think there is a very good chance that we will not manage to catch it all. For this reason I would like to poison it and hope that you might be able to suggest an effective poison.
