Biennial clary

Salvia sclarea | Also known as: Clary, Clear eye, Muscatel sage, Clear-eyes | Rating: 0 votes | Print / Pdf

A deciduous perennial or biennial shrub, salvia sclarea boasts an unmistakably grand appearance and attractive aroma, but it is also a highly practical option for groundcover and produces an impressive spring floral display. Its mid-green foliage comprises large, deeply veined, serrated and hairy heart-shaped leaves growing in a dense clump. Commonly known as the biennial clary, its tall branching stems are topped with floral spikes that feature terminal racemes of usually lavender, but sometimes pink and white blossoms, all emerging from lilac-coloured bracts. The biennial clary thrives in light, humus-rich, well-drained, slightly alkaline soil in full sun. Hardy but invasive, pruning faded flower spikes encourages growth.
