📄 General description
Lemon Verbena is a perennial shrub known for its strong lemon-scented leaves, which are widely used in teas, herbal remedies, and culinary applications.

🌿 Botanical Characteristics:
Family
Verbenaceae / (Verbena family)
Growth and Structure
Aloysia citrodora typically grows as an open, branching shrub that can reach heights of 2 to 3 meters. It develops woody stems and has a somewhat sparse, vertical growth habit if not pruned regularly.
Leaves
The narrow, lanceolate leaves are bright green and highly aromatic, especially when crushed. The lemony scent is due to the presence of citral and other essential oils.
Flowers
Small, pale lilac to white flowers appear in terminal spikes, usually in the dry season or during periods of reduced rainfall.
Pollination
Pollination occurs primarily via insects, especially bees and butterflies, which are attracted to the subtle floral fragrance.
Sexual System
Hermaphroditic
Sexual System Notes
Each flower contains both male and female reproductive organs, making the plant capable of self-pollination.
🌤️ Soil and Climate Preferences
Lemon Verbena prefers well-drained, moderately fertile soils with good sun exposure. In Costa Rica, it grows best in areas that receive plenty of light but are protected from extreme rainfall or persistent high humidity, which can lead to fungal problems.
🍃 Fruit and Use:
General Use
The leaves are the primary usable part of the plant and are commonly used fresh or dried in infusions, desserts, or as a flavoring. They have digestive, antispasmodic, and mild sedative properties and are a popular choice for herbal teas.

Climacteric Category Notes
The fruit is neither used nor considered edible; only the leaves are harvested and processed for use.
🌱 Propagation and Grafting
Propagation is usually done via semi-hardwood cuttings taken during the growing season. The plant roots relatively easily under moist, shaded conditions and does not require grafting.
✂️ Care & Challenges:
Pruning
Regular pruning is essential to maintain a bushy growth form and encourage fresh leaf production. The plant can become woody and sparse without pruning.
Diseases and Pests
It is somewhat susceptible to fungal issues like mildew or leaf spot in very humid conditions. Root rot can occur if drainage is poor. Occasional aphids or whiteflies may appear.
Soil and Fertilization
While not demanding, the plant benefits from light fertilization with compost or well-balanced organic nutrients during its main growth phases. Avoid overly rich soils, which can reduce leaf aroma.
🧺 Harvest Notes
Leaves are best harvested in the morning once dew has evaporated but before intense sun reduces volatile oils. Frequent light harvesting encourages new leaf growth. Dried leaves retain flavor for several months if stored in a cool, dark place.
