Hyssopus officinalis, or hyssop, is an evergreen shrub and part of the lamiaceae or labiatae family. It is found growing in old walls or ledges and on dry and rocky hills. Its flowers can be blue, pink, purple, or white and bloom from July - September.
Hyssop was once so revered as an herbal remedy that it was seen as a virtual cure-all. Currently, however, it is mostly used as a stomach tonic. The young leaves and shoot tips can be used in soups and salads, having a flavour best described as a cross between sage and mint. The flowers can also be added to salads. An essential oil extracted from the leaves has a number of usages as a flavouring, in perfumery, and as an antiseptic.
