Hyssop
(Hyssopus officinalis). An aromatic evergreen bushy herb, native of Southern Europe. It is cultivated for the use of its flowers and tops, which are steeped in water to make an infusion sometimes employed as an expectorant. There are three varieties, known respectively by their blue, red, and white flowers. They may be propagated by seeds, sown in April; by dividing the plants, in spring or autumn; or by cuttings, made in spring, and inserted in a shady situation. Plants raised from seeds or cuttings should, when large enough, be planted out, about 1ft. apart each way, and kept watered until established. They succeed best in a warm aspect, and in a light, rather dry soil. The plants require cutting-in occasionally, but do not need much further attention. Varieties of Hyssop are sometimes employed as edging plants.
