Daisy your purple sage is wonderful - and much better for not flowering. Don't you find that Salvia officinalis falls apart when it flowers, abandoning it's nice rounded shape to crush its neighbours and reveal tough old stems in the centre. The flowers are lovely, of course, but since we choose the purple version for the leaves I'd say it's a bonus that it stays so neat and tidy. Saying that, every time I've tried it the plant has succumbed to a nasty mould.
