Salvia ulignosa.
This is the first winter I've had this plant and I expected it to be cut
down by the frost, indeed I was worried that I hadn't taken cuttings as a
precaution. However it's still as tall as ever and looking nice and green
and healthy with new growths showing along the stems.
So what should I do?
Cut it back to just above ground level, and when should that be done.
Leave it alone, but won't it get too straggly and top heavy.
Plants seldom do what you expect do they.
