Hyssop
Hyssopus officinalis
Zones 4–9
Growing
Establishing hyssop as a permanent fixture in your garden is easiest when you provide well-draining soil with a pH between 6.0 and 8.0. Because this woody subshrub is notably drought tolerant once established, it is an excellent choice for xeriscaping or for containers that may occasionally dry out. If you are starting from seed, wait until the soil has warmed significantly in the spring to ensure better germination. You can also expand your collection by using cuttings or dividing existing plants.
As the plant matures into a woody shrub, you will notice upright branches topped with fragrant, lanceolate leaves and colorful blooms in shades of pink, blue, or white. These flowers are highly effective at attracting pollinators to your garden. To maintain a tidy shape and encourage new growth, you can prune the stems back periodically.
When you are ready to use your harvest, pick the stems when they are at their peak fragrance. Unlike some herbs, hyssop does not continue to improve in flavor once it has been picked, so use it immediately for the best potency. To preserve the herb for later use, you can dry the stems or store them in the fridge. Always keep your harvested hyssop unwashed before storing to prevent moisture from causing rot.
