Hyssop is a low growing shrub with dark evergreen leaves and rich blue flowers.
It has been used for centuries and Gerard felt it was such a common herb that it was tedious to the reader to describe it! This is not the case in the 21st century, hence it is on my specialist list.
Hyssop leaves have a slightly bitter, liquorice, minty flavor and are very good with fatty meats. The flowers of hyssop are delicious in a tossed green salad.
