One of the comments is telling. How does this plant get through the
4" concrete slab and polythene damp proof membrane to appear inside
the house behind skirtings etc. Why isn't there a NHBC guarantee?
Perhaps the house needs to be demolished 'cause it ain't built
properly.


Well i know that a Campsis climber was found behind a sofa growing out
of the skirting of a 1930's house in Amersham! Fairly sure the house
was sound, they didn't knock it down, just killed the plant outside just
in case it came up anywhere else!

Funny you say that. Only yesterday I sprayed with glyphosate a couple
of Campsis shoots which have just appeared, having pushed up through a
weedproof membrane over 3 metres from the original plant. That was cut
down (and the stump drilled and filled with concentrate glyphosate) a
year ago.

Campsis is a persistent weed which I will never plant in a garden again.
It is, like japanese knotweed, not easy to kill with glyphosate,
needing several treatments.
