Perovskia–commonly called Russian sage–bears airy heads of lavender-blue flowers from late summer to fall. Perovskia is a woody-based perennial with erect stems covered in deeply divided, grey-green aromatic leaves. Stems are bare white in winter.
Perovskia is a good choice for planting in a mixed or herbaceous border. Perovskia is a genus of seven species of deciduous subshrub. They are native to rocky sites from Central Asia to the Himalayas.
Perovskia will grow in soils that are sandy, rocky, and other soils low in fertility, as well as regular garden soil, any soil that is well-drained.
Perovskia can grow in place indefinitely.
