Lemon balm (Melissa officinalis) has been a valued herb for centuries, recognized for its refreshing aroma and ease of cultivation. This perennial plant, a member of the mint family, has historically been used in traditional remedies. Its adaptability to different growing conditions makes it a popular choice for gardeners.
Understanding Mandarina Lemon Balm
Mandarina lemon balm stands out from common lemon balm with its unique scent and flavor. Unlike traditional lemon balm’s distinct lemon fragrance, Mandarina emits a clear, sweet, tangerine-like aroma, often described as mandarin orange. This citrusy nuance makes it sought-after for culinary and aromatic uses.
Visually, Mandarina lemon balm differs subtly from its conventional counterpart. It often has a lower, more spreading growth habit, making it an attractive spilling plant in containers or a scented ground cover. Its leaves can also appear more wrinkled or have a softer texture.
Cultivating Mandarina Lemon Balm
Light and Location
Mandarina lemon balm thrives in full sun to partial shade. In hot climates, afternoon shade prevents scorching and maintains lush foliage. This versatile herb grows well in garden beds, herb gardens, or containers. Container growing can also help manage its spread.
Soil and Water
Mandarina lemon balm prefers well-draining, moderately fertile soil. While it tolerates various soil types, good drainage is crucial to prevent waterlogging. Maintain consistent moisture, especially during dry spells, but avoid saturated conditions. Allow the soil to dry slightly between waterings.
Temperature and Humidity
Mandarina lemon balm is a hardy perennial, thriving in USDA Zones 4 through 9. It tolerates a wide temperature range and requires no specific humidity. In colder climates, the plant may die back in winter but regrows vigorously in spring. Mulching around the base provides root protection during dormancy.
Fertilization and Pest Management
Mandarina lemon balm has minimal fertilization needs, especially in fertile soil. Incorporate organic matter like compost every few years to support growth. For potted plants, repot annually with fresh soil. While its natural oils deter many pests, aphids, spider mites, or whiteflies can occasionally appear. Organic control methods include proper air circulation, companion planting (e.g., marigolds, lavender), and insecticidal soap if needed.
Propagation
Mandarina lemon balm propagates easily. Seeds can be sown indoors 6-8 weeks before the last frost or directly outdoors afterward. Seeds need light to germinate and should be barely covered. Cuttings from healthy stems, with lower leaves removed, root well in water or moist medium. Dividing mature plants in spring or autumn is also effective, especially for managing spread.
Harvesting and Utilizing Mandarina Lemon Balm
When and How to Harvest
Harvest Mandarina lemon balm in the morning after dew evaporates, before flowering, for optimal flavor and aroma. This ensures the highest concentration of volatile oils. To encourage new growth and maintain bushiness, cut stems just above a leaf node, or remove up to two-thirds of the plant. Regular harvesting also prevents legginess and bitter leaves from seeding.
Culinary Applications
Mandarina lemon balm’s unique orange-citrus notes make it a versatile kitchen ingredient. Use it for refreshing caffeine-free teas, hot or iced. Fresh leaves complement fruit salads, desserts like pound cake, and can be incorporated into sugars or syrups. It also adds bright flavor to savory dishes like stir-fries, sauces, marinades, soups, or poultry stuffings.
Medicinal and Therapeutic Uses
Lemon balm has a long history in traditional medicine, valued for its calming and soothing properties. It is associated with reducing stress, promoting relaxation, and aiding sleep. It may also improve mood, cognitive function, and alleviate digestive discomforts like bloating, indigestion, and nausea. It exhibits antiviral properties and has been used topically for cold sores.

Ornamental and Aromatic Uses
Mandarina lemon balm also serves as an attractive ornamental plant. Its vibrant green foliage and mounding or spreading habit suit borders, rock gardens, or spilling from containers and hanging baskets. The small white summer flowers attract pollinators like bees, butterflies, and hummingbirds. Crushed leaves can also be rubbed on skin as a natural mosquito repellent.
Storage Methods
To preserve harvested Mandarina lemon balm, several methods work. Fresh leaves store short-term by placing stems in a glass of water, covered loosely with a plastic bag, and refrigerated for up to two weeks (change water daily). For longer preservation, drying is common: hang stem bundles upside down in a cool, dry, well-ventilated area away from direct sunlight, or use a dehydrator/oven on low. Store dried lemon balm in airtight containers in a dark, cool place for up to one year. Freezing is another option: spread whole leaves on a baking sheet before bagging, or chop leaves and freeze in ice cube trays with water or oil.
