Hyssop Seeds

The fragrant blue-flowered herb worth a spot in your garden

Hyssop (Hyssopus officinalis) is a hardy, semi-evergreen perennial in the mint family, grown for its slender spikes of deep blue-violet flowers and its warm, minty, slightly bitter scent. A classic of monastery and cottage gardens, this Mediterranean herb keeps a tidy, shrubby shape and buzzes with bees and butterflies all summer. Its narrow aromatic leaves and long bloom make it as useful along a path or knot-garden edge as it is in the herb bed.

How to grow hyssop from seed

Hyssop is an easy perennial to start from seed. Sow hyssop seeds shallowly, barely covered, in full sun and well-drained soil after the last frost, then thin or space plants about 12 inches apart. Plants grow 18 to 24 inches tall and often bloom in their first year, returning stronger each season. Once established, hyssop is drought-tolerant and thrives in lean, well-drained ground. For the full step-by-step, see our complete guide to growing hyssop from seed.

How to use hyssop

Hyssop earns its keep in the garden and beyond. Plant it as a fragrant, pollinator-friendly edging or in drifts where its blue spikes shine, and cut stems for fresh or dried arrangements. The aromatic leaves and flowers have a long culinary and herbal tradition, used sparingly to season soups and stews, and traditionally brewed into herbal teas. Its strong scent also makes it a fine addition to potpourri and herb sachets.
