I'm glad your S. canariensis turned into an enormous clump. Mine succumbed to winter in 2008, unfortunately. I think the combination of copious rainfall and frosty mornings is not good for Salvias. The ones I have in containers are easier to nurse through the winter because I can put them under the roof overhang and keep them drier. Luckily, I have a good source for S. canariensis right down the street, so I'll have to get some more.
