USDA Hardiness Planting Zones

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).

Tips On Growing Hyssopus (Hyssop)

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.
