Plant details

This salvia is a tall plant for the back of a sunny border, flowering in late summer and autumn. The flowers, almost turquoise blue, appear in short spikes at the top of tall, almost leafless stems and appear to hover among other flowers. Each flower-head has only a few blooms open at a time, so the same heads keep flowering for several months by producing a succession of flowers. Take cuttings in late summer and early autumn to overwinter indoors as an insurance policy The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).

Although it is described above as a tender perennial and only half-hardy, I have kept mine in the garden, unprotected, through the last two extremely cold winters.

My one has been growing in our front garden for the last 5 years,and spreading. The frost has not deminished its growth. And it is loved by the Bees andwasps,ans Hoverflies.
