Lemon verbenaAloysia citrodora

Lemon verbena is an outstanding, intensely fragrant subshrub that belongs in every tea garden. Its leaves release a pure, refreshing lemon aroma at the slightest touch. Native to South America and highly frost-sensitive, it is usually grown in containers in Central Europe and overwintered frost-free. Hard pruning in spring ensures compact, bushy growth and a bountiful harvest throughout the summer.

Storage

Method: Refrigerator, Duration: 1 to 2 weeks, Conditions: In a damp cloth or plastic bag in the crisper drawer, Notes: Fresh leaves keep only for a limited time in the refrigerator. Aroma decreases over time., Method: Drying, Duration: About 1 year, Conditions: Dry in an airy, shady place at a maximum of 35 °C. Protect from direct sunlight., Notes: Lemon verbena dries quickly and retains its aroma well. Store fully dried leaves in airtight containers., Method: Freezing, Duration: 6 to 12 months, Conditions: Seal leaves airtight in a freezer bag., Notes: Frozen leaves retain their aroma well but become soft after thawing, so they are best used for tea or seasoning dishes.

Watering tip: In summer, container-grown lemon verbena requires surprisingly large amounts of water. Drying out leads to immediate leaf drop., Overwintering tip: Do not panic: the plant sheds all its leaves in winter quarters. This is perfectly normal. Reduce watering to a bare minimum.

Pruning

Lemon verbena Pruning

radical_renewal

Goal

radical_renewal

Pruning timing

spring

MarApr

Main cut for spring regeneration. After overwintering, cut lemon verbena back to 10-15 cm above the base. This promotes dense, bushy regrowth. Prune just before budbreak, i.e., in March/April. Only remove dead shoots beforehand.

summer

JunJulAugSep

Harvest and shaping cut. By selectively trimming shoot tips (e.g., during harvest), the plant stays compact and produces more aromatic side leaves. Remove no more than one-third of the leaf mass per harvest to avoid weakening the plant.

Remove

  • Dead and withered shoots (recognizable in spring by brown, cracked bark)
  • Frost-damaged shoots back to healthy wood
  • Weak, thin and spindly shoots
  • Crossing or inward-growing shoots

Preserve

  • 3-5 strong, young main framework shoots per plant
  • Previous year's shoots with good leaf mass and aromatic leaves

Avoid

  • Heavy pruning in autumn (weakens overwintering)
  • Pruning during frost or wet weather (increases risk of rot)
  • Removing more than 2/3 of the shoot mass at once (causes excessive sap loss)

Tools and hygiene

Disinfect pruning shears or a knife with 70% alcohol or methylated spirits before cutting. Clean the blade between different plants to prevent transmission of pathogens.

FAQ

Why is my lemon verbena suddenly losing all its leaves?

This usually has two causes: In autumn/winter, it is the natural shedding of leaves before dormancy. In summer, sudden leaf drop indicates severe underwatering or extreme waterlogging.

Is lemon verbena frost hardy?

No, it tolerates almost no frost (briefly down to -5 °C in extremely sheltered spots). In Central Europe, it must be overwintered in a frost-free environment at around 5-10 °C.

Toxicity notes

Lemon verbena is considered non-toxic. In very large amounts, however, essential oils may cause irritation of the gastrointestinal tract. Pregnant and breastfeeding women should avoid medicinal doses.

Raw consumption

Yes, leaves can be eaten raw. Due to their intense aroma, however, they are mostly used as a flavoring or in drinks.

Seed saving
  1. Part

    Seeds

    Method

    Cut the flower heads after seed ripening (brown, dry) and let them dry in a paper bag. Then remove the small seeds from the capsules.

    Conditions

    Seeds are small and require light to germinate. Store dry and cool.

    Notes

    Lemon verbena produces seeds in Central Europe in good weather, but germination rate is often low. Propagation via cuttings is more reliable in practice.

Seed saving advanced
Isolation distance

Not necessary for self-pollination to maintain varietal purity, but at least 100 m from other Aloysia species, if present.

Population size

At least 10 plants are recommended to maintain genetic diversity.

Cleaning method

Carefully rub the dried seed heads between your fingers, then sift the seeds through a fine sieve. Remove chaff by blowing gently.

Storage conditions

Store cool, dry, and dark. Viability is maintained for 2–3 years under good storage conditions.

Woody crop details
Rootstock relevanceNicht relevant, da Aloysia citrodora in Mitteleuropa meist aus Samen oder Stecklingen vermehrt wird. Veredelung auf Unterlagen ist unüblich.
Renewal pruning relevanceMittel. Ältere Triebe werden nach einigen Jahren weniger aromatisch; ein regelmäßiger Rückschnitt auf 10-15 cm im Frühjahr fördert junge, duftintensive Neutriebe.
Notes

Lemon verbena is a frost-tender subshrub, often grown in containers and overwintered cool in Central Europe. Annual pruning in spring is essential for compact growth and good aroma development.

Ecology
Pollinator valuemedium
Wildlife valuelow
Biodiversity notes

The small, white to pale purple flowers appear in late summer, providing a valuable late-season nectar source for bees, bumblebees, and butterflies.

Practical notes
Watering tip

In summer, container-grown lemon verbena requires surprisingly large amounts of water. Drying out leads to immediate leaf drop.

Overwintering tip

Do not panic: the plant sheds all its leaves in winter quarters. This is perfectly normal. Reduce watering to a bare minimum.

Seasonal content
Spring

Bring out of winter storage, prune hard, and place in a warm, bright indoor spot as budbreak begins, before moving outdoors after the last spring frost.

Summer

Place in full sun, water generously, and continuously harvest shoot tips for culinary use.

Autumn

Perform the last major harvest before early night frosts, drastically reduce watering, and move the plant to cool winter quarters.

Winter

Keep the leafless plant cool (5–10 °C) and the root ball nearly dry, watering minimally every few weeks just to prevent root desiccation.
