Anise Hyssop is a fragrant, flowering herb in the mint family that’s grown for its licorice-like flavor, medicinal uses, and ability to attract pollinators.
What it is
- A perennial herb (comes back every year in most climates like Tennessee)
- Native to North America
- Part of the mint family, but not invasive like some mints
- Known for its upright spikes of purple flowers
What it looks like
- Grows 2–4 feet tall
- Has soft green leaves with a slight fuzz
- Produces lavender-purple flower spikes in summer
- When you crush the leaves, they smell like anise (licorice) and mint
Why people grow it
- Pollinator magnet — bees, butterflies, hummingbirds love it
- Long bloom time — mid-summer through fall
- Easy to grow — drought-tolerant once established
How it’s used
- Leaves and flowers are edible
- Common uses:
- Herbal tea (soothing, slightly sweet)
- Added to salads
- Flavoring for desserts or syrups
- Sometimes used in traditional herbal remedies
Fun fact
Even though it’s called “hyssop,” it’s not the same plant as true hyssop (Hyssopus officinalis). The name comes from a similar look and traditional uses.
Here’s how to get it established and thriving:
Pick the Right Spot
Anise hyssop loves:
- Full sun (at least 6–8 hours daily)
- Well-drained soil (this is critical—wet feet will kill it faster than drought)
In Middle Tennessee, it can handle some light afternoon shade, but more sun = better blooms and stronger flavor.
Planting Your Starter
- Dig a hole about 2x as wide as the root ball, same depth
- Gently loosen the roots if they’re tight
- Place the plant so the top of the root ball is level with the soil
- Backfill and lightly firm the soil
- Water deeply right after planting
👉 Space plants about 18–24 inches apart—they’ll bush out nicely.
Watering (Important Early On)
- First 2–3 weeks: keep soil consistently moist (not soggy)
- After establishment: it becomes drought tolerant
- Water deeply but infrequently—this encourages strong roots
Soil & Feeding
- Doesn’t need rich soil—actually prefers average to lean soil
- Skip heavy fertilizing (too much = floppy growth and fewer blooms)
- If needed, a light compost top-dressing in spring is plenty
Pruning & Maintenance
- Pinch back young plants to encourage bushiness
- Deadhead spent flowers for longer blooming
- Cut back by about 1/3 midseason if it gets leggy
- Leave some flowers at the end of the season if you want reseeding
What to Expect
- Blooms: mid-summer through fall
- Height: typically 2–4 feet tall
- Attracts: bees, butterflies, and hummingbirds
It’s a pollinator magnet—great addition if you’re building a productive garden ecosystem.
Winter Care (Your Zone)
- Hardy in your area (Zone 7-ish)
- Let stems stand over winter for pollinators
- Cut back in early spring when new growth appears
Bonus: It Self-Seeds
Anise hyssop often reseeds itself—but not aggressively. You’ll get a few “bonus plants” next year if you leave some flower heads.
