Anise hyssop has gained popularity among gardeners, herbalists, and culinary enthusiasts for its versatility and ease of cultivation. This hardy perennial thrives in USDA zones 4-9, requiring minimal maintenance once established. The plant's sweet anise-like aroma comes from estragole and other essential oils present in its leaves and flowers, creating a unique flavor profile that enhances both sweet and savory dishes.
Botanical Characteristics and Identification
Anise hyssop (Agastache foeniculum) grows 2-4 feet tall with square stems typical of the mint family (Lamiaceae). Its opposite leaves are lance-shaped, measuring 1-3 inches long with toothed margins. During mid to late summer, the plant produces striking 2-6 inch spikes of small purple flowers that attract bees, butterflies, and hummingbirds. The entire plant emits a pleasant licorice-anise fragrance when touched.
Common Misconceptions Clarified
Despite its name, anise hyssop is neither related to anise (Pimpinella anisum) nor true hyssop (Hyssopus officinalis). This frequent confusion creates challenges when researching anise hyssop vs anise differences. True anise is an annual plant grown for its seeds, while hyssop is a different perennial with narrower leaves and blue flowers. Anise hyssop's botanical name Agastache foeniculum reflects its actual classification within the giant hyssop genus.
| Plant | Scientific Name | Family | Key Characteristics |
|---|---|---|---|
| Anise Hyssop | Agastache foeniculum | Mint (Lamiaceae) | Purple flower spikes, licorice-scented leaves, 2-4 ft height |
| True Anise | Pimpinella anisum | Carrot (Apiaceae) | Annual herb, feathery leaves, grown for aromatic seeds |
| True Hyssop | Hyssopus officinalis | Mint (Lamiaceae) | Narrow leaves, blue flowers, more bitter taste |
Culinary Applications of Anise Hyssop
Chefs and home cooks value anise hyssop for its sweet, subtle licorice flavor that enhances numerous dishes without overpowering them. The leaves and flowers work well in culinary applications of anise hyssop including:
- Infusing honey, vinegar, or sugar with its distinctive flavor
- Adding fresh leaves to fruit salads, jellies, and sorbets
- Flavoring baked goods like muffins, cookies, and breads
- Creating refreshing herbal teas either alone or blended with other herbs
- Complementing fish, poultry, and vegetable dishes as a fresh herb
Unlike stronger anise flavors, anise hyssop provides a more delicate taste that works well in both sweet and savory applications. The flowers make an attractive edible garnish for desserts and cocktails.
Medicinal Properties and Research
Native American tribes traditionally used anise hyssop for respiratory ailments, digestive issues, and wound healing. Modern research into anise hyssop tea benefits shows promising results, though more clinical studies are needed. Current findings indicate:
- Antioxidant properties from flavonoids and phenolic compounds
- Potential anti-inflammatory effects observed in laboratory studies
- Traditional use as a mild expectorant for coughs and colds
- Calming properties that may support relaxation when consumed as tea
While generally recognized as safe for culinary use, consult a healthcare provider before using anise hyssop for therapeutic purposes, especially if pregnant, nursing, or taking medications.
Growing Anise Hyssop Successfully
For gardeners interested in growing anise hyssop in garden settings, this plant offers several advantages. It's drought-tolerant once established, deer-resistant, and attracts beneficial pollinators. Key growing considerations include:
- Soil requirements: Prefers well-drained soil but tolerates various soil types
- Sun exposure: Thrives in full sun (6+ hours daily) but tolerates partial shade
- Water needs: Moderate water requirements; established plants withstand dry periods
- Propagation: Easily grown from seed, division, or cuttings
- Hardiness: Perennial in USDA zones 4-9
Anise hyssop typically blooms from July through September. Regular deadheading encourages continued flowering and prevents excessive self-seeding. The plant may become leggy in poor light conditions, so proper sun exposure remains essential for compact growth.
Safety Considerations
When considering is anise hyssop safe for consumption, current evidence suggests it's generally safe when used in culinary amounts. However, some important considerations exist:
- The compound estragole, present in anise hyssop, occurs in many herbs but has raised safety concerns in very high concentrations
- Pregnant women should avoid medicinal quantities due to potential uterine stimulation
- Those with allergies to mint family plants should exercise caution
- As with any herbal remedy, consult a healthcare provider before therapeutic use
The FDA generally recognizes anise hyssop as safe for food use, but therapeutic applications require more caution and professional guidance.
Harvesting and Preservation Techniques
For optimal flavor and aroma, harvest anise hyssop leaves in the morning after dew evaporates but before the heat of the day. The best time to harvest flowers is when about one-third have opened. Preservation methods include:
- Drying: Hang small bundles upside down in a dark, well-ventilated area
- Freezing: Chop leaves and freeze in ice cube trays with water or oil
- Infusing: Create vinegars, oils, or honey with fresh leaves and flowers
- Tea preparation: Use 1-2 teaspoons of dried herb per cup of hot water
Dried anise hyssop retains its flavor for 6-12 months when stored in airtight containers away from light and heat. Fresh leaves maintain quality for about one week when refrigerated with stems in water.

Frequently Asked Questions
What's the difference between anise hyssop and regular hyssop?
Anise hyssop (Agastache foeniculum) and true hyssop (Hyssopus officinalis) belong to different genera within the mint family. Anise hyssop has purple flowers, licorice-scented leaves, and grows taller (2-4 feet), while true hyssop has blue flowers, narrower leaves, and a more bitter taste. They have different traditional uses and growing requirements.
Can I use anise hyssop as a substitute for anise seed?
While both have licorice-like flavors, anise hyssop provides a milder, more herbal taste compared to the stronger, sweeter flavor of anise seeds. You can substitute fresh or dried anise hyssop leaves in recipes calling for anise, but use about twice the amount since the flavor is less concentrated. The substitution works best in dishes where a subtle licorice note is desired.
How do I prevent anise hyssop from spreading too much in my garden?
Anise hyssop can self-seed vigorously. To control its spread, deadhead flowers before seeds mature, divide plants every 2-3 years, or grow in contained garden beds. Some gardeners plant it near walkways where emerging seedlings are easily managed. Choosing a slightly less fertile soil location can also reduce excessive spreading.
Is anise hyssop safe for pets?
Anise hyssop is generally considered safe for most pets in small amounts, but excessive consumption may cause digestive upset. The ASPCA doesn't list it as toxic to cats or dogs. However, some pets may have individual sensitivities, so monitor your animals if they nibble on the plant. Keep in mind that essential oils concentrated from anise hyssop may be more problematic than the fresh plant.
What are the best companion plants for anise hyssop?
Anise hyssop grows well with other pollinator-friendly perennials like coneflowers, black-eyed Susans, and bee balm. It also complements culinary herbs such as sage, thyme, and oregano. In vegetable gardens, it can benefit tomatoes and peppers by attracting beneficial insects. Avoid planting with aggressive spreaders that might overwhelm it.
