Salvia officinalis is a popular culinary shrub that bears clusters of blue, tubular flowers in summer.
The foliage has a grey/green appearance and the surfaces of the leaves are softly wooly.
The leaves are also quite aromatic and they're often used as a herb in some dishes.
This is a short lived perennial that looks lovely in cottage gardens and pots and is best planted close to the path edge or a pot on the patio so that its fragrance can be enjoyed as you brush past.
