We visited Beth Chatto's garden last Tuesday and in the gravel garden
there was a plant we didn't recognise. It was about 9" to 12" high,
growing in a fair-sized clump and had perfoliate leaves which looked
remarkably like young Eucalyptus leaves. snip

I'm just reading her 'Dry Garden' book, courtesy of Kay's recent offer, and
she briefly mentions a plant that may be the one.
Parahebe perfoliata "whose stems of glaucous circular leaves are
reminiscent of some Eucalyptus species. This plant comes from Australia
which does not surprise me."
There's a pic of it in my RHS Plants and Flowers which looks like your
description. It's also known as Veronica perfoliata.

Ha! I *thought* looking in one of her books might give the solution!
