Perovskia atriplicifolia 'Taiga'
(Russian sage). This is a more compact form of the species, with plenty of lavender-blue upright flower spikes which become more brilliant in colour as they open, and contrast nicely with the fragrant, silvery-green leaves. Full sun and free draining soil, drought tolerant. Loved by bees and butterflies. Slow growing to 60-75cm x 50cm. 9cm pot.
