How to Grow and Care for the Anise Plant (Pimpinella anisum)
Watch feathery foliage flourish into sweet, licorice-like spice with minimal effort.
Anise Plant: Complete Guide to Growing Aniseed at Home
The anise plant (Pimpinella anisum) is an aromatic annual herb valued for its seeds, known as aniseed, which offer a sweet, licorice-like flavor prized in cuisines and confections worldwide. Cultivating anise at home not only provides a fresh supply of flavorful seeds, but also adds an attractive, lacy-leaved plant to your garden. This guide covers every stage of the anise plantâs life cycle, from planting to harvest, and explores how to enjoy this unique herb in your kitchen.
What Is Anise?
Anise is a member of the Apiaceae family, which includes dill, fennel, and parsley. Native to the Eastern Mediterranean and Southwest Asia, it has been cultivated for centuries both for its distinctive flavor and its historical use as a medicinal and culinary herb. Unlike star anise (Illicium verum), a different plant from Asia, true anise is an annual herb with delicate, feathery foliage that grows up to 3 feet (90 cm) tall under the right conditions.
Key Features of Anise
- Height: 1.5 â 3 feet (45 â 90 cm)
- Leaf Appearance: Young leaves are long, green, and slightly lobed; mature leaves are finely divided with a featherlike look
- Flowers: Small white flowers in broad umbels, blooming mid-to-late summer
- Seeds: Brown, ridged, licorice-flavored; ripen late summer to early autumn
- Lifecycle: Grown as a half-hardy annual and will not survive winter
How To Grow Anise
Growing anise is straightforward with the right cultural conditions. Whether you start your plants from seed or purchase seedlings from a nursery, here is a step-by-step guide to successful cultivation at home.
Choosing the Right Location
- Sunlight: Full sun is best â at least 6 hours daily. Provide afternoon shade in hot climates to protect leaves from excessive heat and wilting.
- USDA Zones: 4 to 9 are most suitable; in cooler zones grow in containers and overwinter indoors.
Soil Requirements
- Well-draining, moderately fertile soil
- pH Range: 6.0 â 7.0 (neutral to very slightly acidic)
- Enrich planting area with compost or well-rotted manure for best growth
Temperature
- Ideal Range: 65 â 70°F (18 â 21°C)
- Below 46°F (8°C): growth stalls, risk of frost damage
- Above 75°F (24°C): plants may wilt or dry out â provide extra water and shade if needed
Planting Anise Seeds
- Direct Sowing: In most regions, sow seeds directly into the garden bed after the last frost. Anise does not transplant well due to its deep taproot.
- Indoor Sowing: In cool climates, start seeds indoors in biodegradable pots 6-8 weeks before the last expected frost. Transplant with care to avoid disturbing roots.
- Sowing Depth: Plant seeds 1/4 inch (6 mm) deep; just barely cover with soil to ensure good germination, as seeds need some light to sprout.
- Spacing: Thin or transplant seedlings to 12â18 inches (30â45 cm) apart when true leaves appear.
Watering
- Keep soil moist but not waterlogged. Water young plants regularly to establish deep roots, then reduce frequency as plants mature.
- In hot summer weather, water early morning or evening to prevent rapid evaporation and leaf scorch.
Mulching
- Add a thin layer of mulch around plants to help conserve soil moisture and suppress weeds.

Caring For Anise
Fertilizing
- Anise is not a heavy feeder. If the soil is poor, a light application of balanced organic fertilizer or compost in spring will boost growth.
- Too much nitrogen can encourage leafy growth at the expense of seeds â avoid overfertilizing.
Pruning and Maintenance
- Little pruning is needed. Remove spent flower heads to tidy plants or encourage some rebloom, but allow most to mature for harvesting seeds.
- Thin crowded seedlings to avoid competition and promote air circulation.
Companion Planting
- Grow anise with coriander, basil, or beans. It can improve their flavor and deter certain pests.
- Avoid planting with carrots or fennel, as anise can negatively impact their growth due to similar root systems and nutrient needs.
Common Problems
- Root rot from poorly drained soils. Always plant in loose, well-draining beds.
- Fungal disease if humidity is high and air circulation is poor. Space plants appropriately and water at the soil level.
Harvesting and Storing Anise
When to Harvest
- Seeds are ready late summer to early autumn, once the umbels turn brown and seeds dry on the plant.
- Harvest early in the morning when dew is present to prevent seed loss.
How to Harvest
- Cut the entire seed head (umbel) once seeds mature.
- Shake or gently rub seed heads over a paper bag or tray to collect seeds.
- Allow seeds to dry thoroughly in a cool, shaded area for several days.
Storage
- Store clean, dry seeds in an airtight glass jar or container in a cool, dark place.
- Properly dried seeds stay flavorful for up to 2 years.
Anise Plant Uses
Aniseedâs distinctive, sweet aroma is useful in a range of applications:
- Culinary: Used whole or ground in baked goods, sweet and savory dishes, teas, and liqueurs.
- Medicinal: Traditional herbal remedy for aiding digestion and soothing coughs (consult a professional before use).
- Ornamental: Soft, lacy foliage and delicate blooms are attractive in annual herb beds.
Propagation: How to Grow More Anise
- Seed Saving: Allow a few umbels to mature fully, cut and dry them, and collect seeds for next year.
- Anise rarely self-sows but will readily germinate from fresh saved seed each spring.
Growing Anise in Containers
- Select a pot at least 12 inches (30 cm) deep to accommodate the taproot.
- Use a loose, well-draining potting mix; enrich with compost before planting.
- Place in a site with full sun and water regularly to keep soil just moist.
- Move containers indoors when frost threatens or temperatures fall below 46°F (8°C).
Common Pests and Diseases
| Pest/Disease | Symptoms | Prevention & Solution |
|---|---|---|
| Aphids | Clusters of tiny green/black insects on stems and leaves; sticky residue (honeydew); distorted growth | Blast with water, attract beneficial insects, use insecticidal soap if infestation is severe |
| Root rot | Wilting, stunted plants, brown roots | Ensure soil drains well; do not overwater |
| Powdery mildew | White powdery patches on leaves and stems | Increase air circulation, water at soil level, remove infected foliage |
| Fungal wilt | Sudden wilting, yellowing leaves | Rotate crops, destroy affected plants, do not plant anise in same site for several years |
Frequently Asked Questions (FAQs)
Q: Is anise the same as star anise?
A: No. While both share a sweet, licorice-like flavor, anise (Pimpinella anisum) is an annual herb native to the Mediterranean, while star anise (Illicium verum) is an evergreen tree from Asia with star-shaped fruit. They are botanically unrelated and should not be confused in recipes or cultivation.
Q: Can I grow anise indoors?
A: Yes, provided the plant receives at least 6â8 hours of direct sunlight daily (in a bright window or under grow lights) and is planted in a deep container. Anise prefers the open air but can be grown indoors to extend the season in cooler climates.
Q: How long does it take for anise seeds to mature?
A: After sowing, anise typically takes about 3â4 months to flower and produce viable seed. Harvest seeds late summer to early fall when they turn brown and dry on the plant.
Q: Is anise safe for pets?
A: Anise is generally safe for people when consumed in normal food amounts, but consult a veterinarian before giving any part of the plant to pets, as different species have varying sensitivities.
Q: Can you use anise leaves?
A: Both the seeds and young leaves are edible. Tender leaves have a mild licorice flavor and can be used fresh in salads, teas, and as a garnish, though the seeds are more commonly used for strong flavor.
Tips for Cooking With Anise
- Add aniseed to breads, cookies, or cakes for a classic licorice undertone.
- Infuse seeds in milk for use in custards and creamy desserts.
- Brew anise seed in teas or digestive infusions.
- Use ground anise in savory dishes for a Mediterranean touch.
