I grow Rosmarinus 'Severn Sea', which Jekka McVicar's site call "frost
hardy". However, it has survived in my garden for 4-5 years, despite
the heavy snowfall and frosts of the last two winters. It is on heavy
clay, but at the front of a retaining wall, perhaps similar to your
intended site. The wind often whips it and tosses it back on itself,
so it is fairly exposed. There was a tiny bit of damage last year, but
the plant is doing well. It has the most beautiful blue flowers

But we lose it here, due more to wet than cold, probably. I don't think
we'd ever call it hardy and -15C is an unattainable dream!

Well as I say -15C is an outer limit. As you know our conditions aren't
that different: lots of wet, not too cold. But every once in a while we
get a few weeks of that nasty east wind, that clears out the sea air and
brings in the continental cold. It wreaks havoc with the more tender
plants. The wall where the rosemary is to go is very exposed, so the
hardier I can get, the better!
