Hyssop
Hyssopus officinalis
A compact, semi-woody aromatic herb of the mint family with narrow, dark-green leaves and dense spikes of deep-blue (occasionally pink or white) flowers from midsummer onward. A classic cottage- and knot-garden plant, hyssop is one of the very best bee and butterfly plants in the herb border, drawing honey bees, solitary bees, and nectaring butterflies to its blue flower spikes. It is also a traditional culinary and medicinal herb: the leaves and flowers carry a strong, bitter, minty-camphor flavour used sparingly in cooking and as a flavouring in liqueurs (it is one of the herbs in Chartreuse). Long grown as Hyssopus officinalis, its accepted botanical name is now Dracocephalum officinale, though it remains universally known and sold under the familiar Hyssopus name. It is native to southern Europe and the Mediterranean across to central Asia (POWO, Kew), and carries that origin into the garden: it is easy, drought-tolerant, and sun-loving, asking only full sun and sharp drainage, and it gets woody and straggly unless clipped after flowering to keep it neat.
