Sadly not, as it is rather soft stemmed.
A must have in the garden somewhere though!

It's an annual, so it won't survive the winter, sadly.

It does have the excellent habit of self-seeding, though! :-)))

Brings up images of the maze at Hogwarts, though!

LOL.

Thanks very much to everyone. Any suggestions as to what might be suitable?

It rather depends on the aspect and conditions in that area of your garden, Slowmover. Is it sunny, for example, and how cold does it get there? What sort of height of hedge were you looking for? Is the soil free-draining?
