Salvia nemorosa Caradonna (9cm)
Glowing purple stems with violet-blue flowers from June to October. The grey-green, aromatic foliage also makes an attractive accent in the summer border. A compact variety that is perfect for adding a splash of colour at the front of a well- drained herbaceous border or gravel garden. It thrives in a sunny spot and will become drought tolerant once established. The blooms are a magnet for butterflies and bees. Height 60cm, spread 60cm.
