Can anyone recommend a hardy perennial salvia which will survive a Scottish winter? Garden is relatively sheltered but have not managed yet to get one to survive another year.
I'm finding that Salvia Royal Bumble is holding up particularly well Hogweed. I'm glad since I've forgotten to take some cuttings. It's in a sunny well drained part of the garden, where Salvia Amistad fails each year. I'm in Edinburgh btw.
Salvia caradonna is a good hardy variety.
A lot depends on your soil, rather than geography. I live on the famously mild Isle of Wight, but with waterlogged clay soil, there aren't many salvias that can survive a winter.
I've found caradonna to be a success too
I've had a Hotlips outside in a large pot for the last 3 winters up here in the Pennines and it has survived OK with snow and frost at times.
It got too big to go in the GH, so I took cuttings and left it out to take its chances. This is probably your safest course of action too, if you have anywhere to keep them till spring, as ones like Amistad, African Skies and Neon all root easily and grow quite fast and this is how I keep mine going.
I've lost Hotlips several times in the cold winters of SW France, but Salvia Blauhugel and Caradonna have survived and are now several years old.
Caradonna it is then if I can find it online. May take a trip to the faraway garden centre this weekend and see if they have it in or can suggest any more. Thanks for all your help.
I don't know where you live Hogweed but S. Caradonna is quite wildly available in the GCs round me but I'd hold of for a few weeks yet as those will look decided dead in their pots right now. I forgot to add that both S.x Sylvestris Rose Queen and Blue Queen do well here too.
