rustic weeping rosemary

 I'm looking for the hardiest possible weeping rosemary cultivar.  To
drape down a low wall.  We very occasionally see -15C. Any suggestions?

Thanks,

My experience is that quite a few can take that, if they are in
very well-drained conditions.  But I agree that you want to avoid
the delicate ones.

You could try emailing a few nurseries in the north of Scotland and ask
them if they have any ideas. For example: http://www.poyntzfieldherbs.co.uk/

They list several, but I can't see a hardy weeping variety there.

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

In my experience it isn't winter hardiness that kills it so much as wet
feet and/or a nasty white fungal branch rot that starts from the top.

Dry continental style cold probably won't harm it but many days of cold
damp conditions lingering around freezing point will.

The gnarled remains of a several decade old rosemary that finally gave
up the ghost last year adorns my fern garden.

Unknown cultivar I have grows fine on heavy clay up against a roughly S
facing garage wall which gives it a bit of protection from the elements
up here in North Yorkshire. Mine has survived -18C.
