Latin name

Common name

Type
Perennial
Family
Lamiaceae

Hyssop is an aromatic and medicinal perennial plant highly valued for its fine, fragrant foliage and its spiky blue, mauve, pink, or white flowers, depending on the variety. Its compact and upright habit adds structure to herb gardens, sunny borders, flower beds, and Mediterranean-style landscapes. It is ideal for adding fragrance, color, and a natural touch to dry areas, rock gardens, and ornamental vegetable gardens.

Easy to grow, hyssop prefers a full-sun location in light, well-drained, and rather dry to moderately fertile soil. Once established, it tolerates heat and dry periods quite well, making it an excellent plant for low-maintenance gardens. Light pruning after flowering helps to keep the plant denser, more compact, and well-branched, while encouraging beautiful new growth.

Both decorative, aromatic, and very useful for biodiversity, hyssop attracts bees, butterflies, and several other pollinators. Its fragrant leaves can be used sparingly in cooking, as an infusion, or to flavor certain dishes, sauces, and marinades. It is an excellent perennial for gardeners looking for a resistant, melliferous, fragrant plant that is easy to integrate into an herb garden or a sunny border.
