Hyssopus officinalis ssp. aristadus (Blue Hyssop) is one of the very best Old World plants for attracting and feeding bees and bumble bees. A medicinal herb, its aromatic foliage, and bright blue flowers are a highlight of the mid-summer garden. Drought resistant/drought tolerant plant (xeric).
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low
temperatures; the lower the zone number the colder the winter.
If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will
survive the winter temperatures in your area.
If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack
of freezing winter temperatures do not provide a time for winter dormancy (rest).
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.)

Hyssopus (Hyssop) is a group of Old World herbs with blue flowers and aromatic foliage that is highly resistant to browsing animals and a favorite nectar source for bees of many types.
Preferred growing conditions:
Plant in a fast-draining, infertile soil with full sun. Don't plant in clay soils.
Mulch with gravel or not at all.
Water regularly the first growing season to establish the plant. Thereafter, infrequent but deep watering is all this plant needs.
Deadheading helps to keep the foliage looking tidy, but may not extend the flowering season.
Fertilize lightly in the fall with Yum Yum Mix.
Special comments:
Hyssopus can be short-lived perennials and should be encouraged to re-seed themselves by leaving some seed heads on the plants and mulching with small diameter gravel mulch.
Leave standing over the winter and trim off any winter killed stem tips, but don't cut the plant back to ground-level as this will kill the plant.
