I have a Salvia Patens and Salvia Guaranitica. I only grew them for the first time this year and found out that they are not fully hardy. I read that some growers treat these as annuals but they really are true perennial plants and they are a bit expensive to consider replacing annually. So has anyone successfully overwintered these plants in the ground. If so did they survive the severe cold winters of 2009/10 and 2012/13?

I lift mine and "roughly" stick them in a pot and put some compost around the roots, and chop the tops back by about 2/3rd.
I also take cuttings off them (in August, might still work but its a bit late).
I find that the plants that I over winter are much more significant the second year planted out, and if I get to the point of having too many I will leave half out as well as overwintering a core stock and some cuttings.K's Garden blog the story of the creation of our garden -
Aaaah, now I'm panicking. I bought a couple of Salvias this year. Wendy's Wish, another Aussie hybrid. They are fantastic, and still blooming! Looks like I'll be lifting them.
Looks like I'll be buying your Blue ones next year, too, bend1pa, they're lovely!

Unlikely to be hardy, except in a mild winter / sheltered spot.Originally posted by Glutton4... View Post
My favourite is Salvia Amistad - very floriffic and a strong colourLooks like I'll be buying your Blue ones next year, too, bend1pa, they're lovely!
I'll probably have some spares in the Spring, if you make a note and jog my memory then I can send you any spares that I have

Hi Kristen. Only question is where did you store them? Was it in a greenhouse, inside the house or dark cold garage, etc?Originally posted by Kristen View PostComment

I stored them in a frost-free greenhouse. Not sure if they would be happy in the dark for the winter (but they might be ) but if that is the only frost free spot available then perhaps outside during mild spells / days and into the garage/etc. during Arctic weather perhaps?

Do they not use plants as legal highs ??

I still haven't dug mine up yet and the leaves and stems are still green. I see that the temperature is going to drop to -2° C this coming Monday night. I did put down a couple of inches layer of leaf mould around the crown of the Salvia last week. I was wondering if this will this be enough protection against the frost, or would you advise digging it up and storing it?
I know Dysons (famous Salvia growers) advise this method with their half hardy Salvias. They are in rural Kent where the temperatures often get well below 0° C in winter, but they told me they always leave theirs in the ground and use a protective mulch.Comment

I think that if you have soil that drain well - e.g. sandy - that helps a lot with tender plants. On heavy clay / poor drainage then the problem is greater because of the tendancy to rot.
If you have spares (cuttings taken in late Summer, or one or two lifted and potted) then trying them left out will not be a total risk.
I find mine flower earlier, and make bigger bushes, if I lift them rather than leave them in the soil over winter (similarly Dahlia and Cannas) as they make an earlier start in the Spring - but my garden is not what I would call "sheltered".K's Garden blog the story of the creation of our gardenComment
