Like a giant herb robert??

I've got that. IIRC it tends to die in winter and reseed itself, but I
may be getting muddled.
Jill claims not to recognise it,

I don't remember saying that:-)

but the original came from her.

In that case it's probably G. rubescens (biennial, slightly tender and
like a *mega* herb robert, in its ability to seed everywhere and grow
**big**!) Other similar ones are G maderense and G canariense but they
are more tender.
