Russian sage
Perovskia atriplicifolia
July to September
For the bees
When the meadow scorches in high summer, its lavender-blue spikes stay full of nectar. One of the busiest beds in the garden, morning to evening.
The tradition
A close cousin of the sages, with silvery, camphor-scented foliage. Crush a leaf and the scent stays on your fingers — slugs and deer keep away; the bees don’t.
