🌿 Bushy lippia (*Lippia alba*)
🔤 Name English / nombre español / Name Deutsch
Bushy lippia / Juanilama / Anisverbene
📄 General description
Lippia alba is a strongly aromatic perennial shrub native to tropical and subtropical America. In Costa Rica it is commonly known as juanilama and is cultivated mainly for its fragrant leaves, which are traditionally prepared as an herbal infusion. The species is highly variable in growth form, leaf shape and essential-oil composition. Different plants may therefore smell lemony, minty, anise-like, camphoraceous or otherwise aromatic, depending on their chemotype.
🌿 Botanical Characteristics:
Family
Verbenaceae / (Verbena family)
Growth and Structure
The species grows as a many-branched shrub or subshrub, usually reaching about one to two metres in height. Its slender stems may be upright, arching or partly decumbent. Lower branches can root when they remain in contact with moist soil, allowing the plant to spread naturally.
Leaves
The leaves are simple, aromatic and usually arranged opposite each other or occasionally in whorls of three. They are generally oval to oblong, have serrated margins and possess a slightly rough or hairy surface. Crushing the leaves releases a strong scent whose character varies considerably among chemotypes
Flowers
The small tubular flowers are grouped in compact, rounded or short cylindrical flower heads arising from the leaf axils. The corolla may be white, pale pink, lavender or light purple, often with a yellowish centre. Flowering can continue intermittently for extended periods under warm tropical conditions.
Pollination
The small flowers are visited and pollinated by insects, particularly bees and other small flower-visiting insects. The flower heads can also provide nectar and pollen for beneficial insects in a diversified garden or agroforestry system.
Sexual System
Hermaphroditic
Sexual System Notes
Individual flowers contain both functional male and female reproductive structures. Fruit and viable seed production may nevertheless vary between plants, growing conditions and chemotypes.
🌤️ Soil and Climate Preferences
Lippia alba grows well in warm tropical and subtropical climates and occurs from sea level into moderately elevated areas. It adapts to several soil types but performs best in fertile, well-drained soil with regular moisture. Established plants tolerate short dry periods, while prolonged waterlogging can damage the roots. Full sun encourages compact growth and aromatic leaf production, although the plant also tolerates partial shade. In the humid Caribbean lowlands of Costa Rica, good drainage and airflow are especially important.
🌿 Fruit and Use:
General Use
The aromatic leaves are traditionally used in Costa Rica to prepare juanilama tea. They may be used fresh or dried, either alone or in herbal mixtures. The plant is also cultivated for its essential oil and is widely used in traditional medicine, especially in preparations associated with digestion, relaxation and general discomfort. These traditional uses should not be treated as proven medical efficacy, and the chemical composition can differ substantially among individual plants and chemotypes.
Ripening Season in Costa Rica
The fruits are not normally harvested or consumed in Costa Rica, and no relevant commercial ripening season is established. Flowering and occasional fruit formation may occur intermittently during much of the year under warm, humid conditions.
Common Fruit Traits
The fruits have no established use as food for humans and are normally left on the plant for natural seed development.
Climacteric Category
Irrelevant (not consumed successfully by humans)

Climacteric Category Notes
The tiny fruits are not normally consumed or harvested as food. Climacteric behaviour is therefore irrelevant for the practical use of this species, which is cultivated primarily for its aromatic leaves and young shoots
🌱 Propagation
Stem cutting
Use healthy, partly mature stem sections in a moist but well-drained substrate. Light shade is preferable until new growth begins. Vegetative propagation helps preserve the characteristics and aroma profile of a selected plant.
Layering
Branches that have rooted naturally after touching the soil can be separated from the parent plant and replanted.
✂️ Care & Challenges:
Pruning
Regular light pruning encourages branching and the production of young leafy shoots. Long, weak or ground-trailing branches can be shortened to maintain airflow and prevent an excessively open form. When harvesting leaves, enough foliage and healthy stem growth should remain for rapid recovery. Old or poorly productive shrubs can usually tolerate stronger rejuvenation pruning.
Diseases and Pests
The species is generally robust, but plants in very humid or poorly ventilated locations may develop fungal leaf spots, stem problems or root rot. Sap-feeding insects such as aphids, whiteflies, scale insects and mites may occasionally affect young growth. Caterpillars and other leaf-feeding insects may also occur. Good drainage, moderate plant density, removal of badly affected material and regular observation usually provide the best preventive management.
Soil and Fertilization
The plant benefits from soil rich in organic matter but generally does not require heavy fertilization. Mature compost, leaf mulch and other mild organic amendments can support continued leaf production. Excessive nitrogen may produce soft growth with reduced structural strength and potentially altered aromatic quality. Mulch helps conserve moisture, but it should not remain packed directly against the base of the stems.
