The message
from tonyjeffs contains these words:

Our house is on a corner. At the side of the garden is a privit hedge,
and at the end is a stone wall. *The corner where the two meet is very
vulnerable to burglars, and there've recently been 3 in the street.
So... we need either barbed wire (joking) or a nice thorny bush to
make that access route less attractive.

How about Poncirus trifoliata? The scent of the flowers is lovely
and it can become quite vicious ...

Aha!
We have some of that struggling to grow in another part of the hedge.
I didn't know what it was. And I didn't know it had a smell! I'll
transplant it to the corner.

Where it is, it has always been small, about 18". Perhaps smothered by
the privit. Can it grow to 7"

Thanks
