sweet woodruffGalium odoratum
Sweet woodruff (Galium odoratum) is a perennial herbaceous plant, primarily known for its sweet, vanilla-like aroma that develops upon wilting or drying of the leaves. Native to European deciduous forests, it is a popular groundcover for shady garden areas. Traditionally, it is used to flavor beverages like May punch (Maibowle), as well as for desserts and teas.

Storage
Storage methods: Drying, Freezing (leaves), Storage duration: Dried: 6-12 months; Frozen: up to 6 months, Notes: For the best aroma, sweet woodruff should be dried. Fresh leaves only keep for a short time in the refrigerator.
Sweet woodruff is a low-maintenance plant that works well as a groundcover. Ensure a shady to partial shade location with moist, humus-rich soil. Propagation is easiest by dividing rhizomes in spring or autumn. Harvest leaves before flowering for the best aroma. Use with caution in large quantities due to coumarin content.

FAQ
Where does sweet woodruff grow best?
Sweet woodruff prefers a shady to partial shade location with moist, humus-rich, and well-drained soil. Locations under trees or shrubs are ideal.
When and how should sweet woodruff be harvested?
Leaves should be harvested before flowering, ideally in April or early May. Cut the stems just above the ground. The aroma develops best when the harvested stems are slightly wilted.
Is sweet woodruff poisonous?
Sweet woodruff contains coumarin, which can be liver-damaging in high doses. However, in the usual quantities for culinary purposes (e.g., May punch), it is harmless. Excessive consumption should be avoided, especially by pregnant women or individuals with liver problems.
How do you propagate sweet woodruff?
The easiest method is by dividing the rhizomes in spring or autumn. Sweet woodruff can also be propagated by sowing in autumn, as it is a cold germinator.

First checks
- Check for waterlogging
- Examine roots for mushiness
Symptom
Poor growth / Stunted plants
Possible causes
- Too much sun
- Too dry soil
- Poor soil quality
- Competition from other plants
First checks
- Check site conditions (shade, moisture)
- Check soil for humus content
- Assess competition from other plants
Prevention strategy
Cultural
- Choose a shady to partial shade location
- Ensure humus-rich, well-drained soil
- Maintain consistent soil moisture, but avoid waterlogging
- Mulch the soil to retain moisture and suppress weeds
Monitoring
- Regularly check soil moisture
- Observe leaves for discoloration or wilting
Organic first response
- Adjust watering schedule (less for waterlogging, more for dryness)
- Improve drainage if waterlogging is present
- Provide more shade if leaves are scorched
Notes
Sweet woodruff is generally very robust when grown in a suitable location with the right conditions. Most problems can be resolved by adjusting the environment.
Phenology
Stages
- Spring emergence
- Leaf development
- Flower bud formation

- Fruiting
- Seed ripening
- Autumn dieback (aerial parts die, rhizomes overwinter)
Notes
Leaves are harvested before flowering, as coumarin content and aroma are most intense then. After flowering, the aroma diminishes.

Flower color
- White
Flower type
Small, star-shaped flowers in loose cymes

Notes
The small white flowers appear in clusters above the foliage and are rather inconspicuous.
Harvest

Harvest notes
Leaves are ideally harvested in April or early May, just before the plant begins to flower. At this time, the coumarin content is highest and the aroma is most intense. After flowering, the aroma diminishes, and coumarin content may change.
Harvest details
Harvest frequency
Once annually for the main harvest, light harvesting possible as needed.
Harvest indicators
- Fresh, green leaves
- Before flower buds open
Post harvest handling
Tie harvested stems into small bundles and hang upside down in an airy, shady place to dry. Alternatively, spread them on a rack. After drying, strip the leaves from the stems.
Storage
Storage methods
- Drying
- Freezing (leaves)
Storage duration
Dried: 6-12 months; Frozen: up to 6 months
Notes
For the best aroma, sweet woodruff should be dried. Fresh leaves only keep for a short time in the refrigerator.
Storage details
General storage category
Dried herbs
Storage life
Dried sweet woodruff retains its aroma in an airtight container in a dark, cool place for 6 to 12 months.
Processing options
- Drying for tea or punch
- Freezing in ice cubes for drinks
- Making syrup or extract
Processing use
Primary processing
Drying the leaves for flavoring drinks and dishes.
Secondary processing
Production of sweet woodruff syrup, extract, or spirit. Leaves are often slightly wilted to intensify the aroma.
Notes
Sweet woodruff's characteristic aroma only develops when the leaves wilt or dry, as coumarin is released.
Kitchen usage
Culinary uses
- May punch (Maibowle)
- Sweet woodruff syrup
- Jelly
- Desserts (pudding, ice cream)
- Lemonades
- Tea
Flavor profile
Sweet, vanilla-like, hay-like, slightly bitter
Pairing suggestions
- White wine
- Sparkling wine
- Fruits (strawberries)
- Cream
- Curd cheese
Preparation methods
Fresh or dried leaves are steeped in liquids (wine, water, milk) for a short time to extract the aroma. Do not boil to avoid bitterness.
Notes
Sweet woodruff should be used sparingly, especially in larger quantities, as it contains coumarin. For May punch, the slightly wilted stems are briefly steeped in wine.
Safety and edibility
Edible parts
- Leaves
- Flowers (in small quantities)
Inedible or caution parts
- High doses of leaves (due to coumarin)
Toxicity notes
Sweet woodruff contains coumarin, which can be liver-damaging in high doses. Coumarin content is highest before flowering. Moderate consumption is safe, but excessive intake should be avoided. Pregnant women and individuals with liver conditions should be particularly cautious.
Raw consumption
Yes, in moderation. Leaves are often slightly wilted or dried to intensify the aroma and stabilize coumarin content.
Seed saving
Seed maturity indicators
The small, spherical fruits (schizocarps) turn brown and dry and detach easily.
Harvest method
Carefully collect seed heads by hand as soon as they are ripe. They can fall off easily, so regular checking is important.
Cleaning method
Gently rub the dried seed heads to separate the seeds from the husks. Sieve out chaff and other plant material.
Storage conditions
Store dry, cool, and dark in an airtight container.
Notes
Sweet woodruff often self-seeds if conditions are right. Seeds require a cold period (cold germinator) for germination.
Seed saving advanced
Special considerations
Seeds require cold stratification to germinate. This can be achieved by sowing in autumn or artificial stratification.
Notes
Vegetative propagation by dividing rhizomes is easier and more reliable than seed saving for home gardens.
Woody crop details
Notes
Sweet woodruff is a herbaceous, strongly spreading plant and not a woody variety in the classic sense. The information provided here relates to general cultivation and propagation.
Ecology
Biodiversity notes
While not a primary food source for wildlife, sweet woodruff provides habitat for small insects as a groundcover and improves soil structure.
Practical notes
Sweet woodruff is a low-maintenance plant that works well as a groundcover. Ensure a shady to partial shade location with moist, humus-rich soil. Propagation is easiest by dividing rhizomes in spring or autumn. Harvest leaves before flowering for the best aroma. Use with caution in large quantities due to coumarin content.
Seasonal content
Spring
In spring, sweet woodruff emerges and is ready for harvesting its aromatic leaves before flowering. This is also the best time to propagate new plants by division.
Summer
In summer, sweet woodruff requires regular watering during dry spells to maintain its green color and vitality. It serves as an attractive groundcover.
Autumn
Autumn is a good time to divide and plant sweet woodruff. The above-ground parts die back, but the rhizomes overwinter well.
Winter
Sweet woodruff is winter-hardy. The above-ground parts die back, and the roots survive the winter in the soil.
