Hyssop is a hardy woody perennial evergreen (sub shrub) from the Mediterranean region. It produces lovely sprigs of bright blue flowers, and attracts many types of beneficial pollinators. The aroma of the flowers, either fresh or dried, is completely unique and one of the best and strongest of all herbal aromas. Plants quickly form into a short woody shrub that is 46-61 cm (18-24”) high that can be shaped with trimming. Flowers stalks can reach 91 cm (36”) tall.
Sow seed in spring in flats. Scarify seed lightly on fine sandpaper. Barely cover seed, tamp well, and keep evenly moist, warm and in the light until germination, which takes 7 to 10 days. Transplant to pots after second set of true leaves appears. Within a few weeks the seedling will have grown sufficiently to transplant out to the garden. Thin or transplant to 61-91cm (24-36”) apart.
Soil Conditions: Well worked loose soil. Sow the seeds on the surface of dampened, sterilized seed starting mix under bright light with bottom heat. Keep watering to a minimum. Herbs grow best in well-drained fertile soils, so a garden bed that is well prepared with plenty of organic matter will increase your chances of success. Maintain a soil pH of 6.5. After seeding or transplanting, keep the soil moist and well weeded. When seedlings are large enough, harden them off and transplant to the garden or to containers spacing them at 20 cm (8”) apart.
Planting Depth: (Surface Seed and moisten seed). Lightly press into the planting medium.
Days to Maturity: 85-90 days. Pick when plant is able to support harvesting.
Sun/Shade: Full Sun
Spacing after Thinning: 61-91cm (24-36”) apart
Additional Information Open pollinated - untreated Seeds. Plant Hyssop seeds for a lovely aromatic edging for the herb garden. Hyssop goes dormant in winter, trim and cut back the bare stems and branches to help prevent snow damage. In early spring a fresh batch of leaves will emerge over the whole plant all at once. Hyssop is a durable plant and can be grown in a wide range of climates and conditions. It requires light, rich soil and full sun at least 6 hours per day, conditions that also make it ideal for growing indoors.
