Hyssopus officinalis ssp. aristadus (Blue Hyssop) is fragrant herb traditionally used for brewing tea and as a medicinal plant. Hyssop is right at home in the ornamental garden. Its deep green foliage and dark-blue flower spikes are a delight in mid-summer, when many other plants are looking beat from the heat. Extremely attractive to bees and butterflies, it is a wonderful companion plant to pink and orange Agastache. This is a wonderful lavender substitute for colder climates. Cut back to green foliage in early to mid-spring. 18-24″ tall x 12-15″ wide. (Seed propagated.)
