Citrus medica - The Ancient Citron with Aromatic Fruits

Discover Citrus medica, the citron, an ancient citrus species valued for its distinctive fruits, intensely aromatic rind and long history of cultivation. With its evergreen foliage, fragrant flowers and characterful fruit, this unusual citrus tree brings Mediterranean appeal to a plant collection.

Organically cultivated at TOMs FLOWer CLUB and never over-fertilised, our citrus plants are grown with an emphasis on natural development, healthy roots and quality before quantity. The tree is planted in a well-drained, self-mixed organic substrate adapted to the needs of citrus plants.

Why This Plant Stands Out

• An ancient citrus species with a distinctive botanical and culinary history.

• Large fruits with a particularly thick, aromatic rind.

• Evergreen foliage and fragrant flowers, with the potential to produce fruit under suitable growing conditions.

• A rewarding citrus plant for collectors and enthusiasts who appreciate unusual fruiting trees.

• Organically cultivated without excessive fertilisation.

Plant Characteristics

Botanical name: Citrus medica
Common name: Citron
Plant type: Evergreen citrus shrub or small tree
Family: Rutaceae
Foliage: Green, aromatic leaves
Flowers: Fragrant, white to purplish-tinged flowers
Fruit: Often large, with a thick, aromatic rind; fruit shape and size depend on the cultivar
Growth: Can develop into a larger shrub or small tree over time, depending on conditions and pruning

Cultivation & Care

Light: Provide a very bright, sunny position for healthy growth and fruit development.

Outdoor season: In Switzerland, place the plant outdoors in a sheltered, sunny location once frost is no longer a concern. Outdoor cultivation is generally suitable from spring to autumn, depending on local conditions.

Winter care: Overwinter in a bright, frost-free location. A cool environment around 10 °C is suitable, with watering reduced according to temperature and growth. Avoid cold draughts and waterlogged roots.

Watering: Water thoroughly, then allow excess water to drain. Keep the substrate moderately moist during active growth and avoid prolonged dryness or standing water.

Substrate: A loose, well-drained citrus substrate supports healthy root development. The plant is grown in a self-mixed organic substrate adapted to citrus requirements.

Pruning: Prune selectively in spring when necessary to maintain a balanced shape and encourage healthy growth. Avoid unnecessary heavy pruning, particularly when the plant is carrying flowers or developing fruit.
