Frequently Asked Questions

Is Anise Hyssop a fast-growing or slow-growing plant?

  • Anise Hyssop is a fast-growing perennial that will fill in quickly to create an impressive display. It establishes rapidly and blooms all summer long with minimal care required. Plant it in sunny areas where you want quick color and pollinator activity.

Is Anise Hyssop deer resistant?

  • Anise Hyssop is generally deer resistant due to its strong aromatic foliage that smells like licorice and mint. Deer typically avoid plants with intense fragrances, making this pollinator magnet a smart choice for areas with deer pressure. Shop at Nature Hills for this dual-purpose perennial.

How do I care for Anise Hyssop during winter in colder zones?

  • Anise Hyssop is quite cold hardy and will naturally die back to the ground after frost. In zones 4-8, simply cut stems down to 2-3 inches in late fall. Apply a light mulch layer around the crown for extra winter protection in the coldest zones.

Does Anise Hyssop need to be fertilized and how often?

  • Anise Hyssop thrives without regular fertilization and actually performs better in lean soils. Over-fertilizing can reduce flower production and weaken the plant's natural drought tolerance. A light application of compost in early spring is sufficient for most garden soils.

Will Anise Hyssop self-seed and spread in my garden?

  • Yes, Anise Hyssop readily self-seeds and will naturalize in your garden. It fills in fast to create marvelous displays with minimal care. Allow some flowers to go to seed if you want more plants, or deadhead to prevent spreading. Find quality Anise Hyssop plants at naturehills.com.
