Blue Hyssop (Hyssopus)

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.
