Perovskia
Perennial
Blue
20cm pot
 
Perovskia (also known as Russian sage) is a handsome sub-shrub that produces masses of lavender-coloured flowers held on branching, aromatic stems.
 
A fantastic addition to a herbaceous border or gravel garden, the flowers are a magnet for pollinating insects. For best results, grow in full sun in well-drained soil. Prune hard each year in mid- to late spring create a woody framework a few inches high – this encourages strong new growth that will carry flowers later in the year.
