Citrus × latifolia – Lime

Citrus × latifolia – Lime

Citrus × latifolia – Lime is a Persian or Tahiti lime type grown for glossy evergreen foliage, white fragrant flowers and medium-sized limes with aromatic green rind. It forms a small tree in warm climates and stays manageable in a container with seasonal pruning, regular feeding and a bright protected winter position above about 10°C.

The fruit is usually picked green for its fresh acidity, although mature limes can turn yellow on the tree. In container culture, Citrus × latifolia develops medium-sized fruit, a clean woody framework and a rounded crown that responds well to strong seasonal light and protected wintering above about 10°C.

Persian lime foliage, flowers and green fruit

• Fruit: Medium-sized limes with aromatic rind and juicy segmented flesh.
• Foliage: Evergreen, glossy leaves with a clean citrus scent when bruised.
• Growth habit: Woody, branching small tree that can be kept compact in a pot.
• Flowers: White scented citrus blooms that can develop into fruit under strong light.
• Pot-grown habit: A movable fruiting citrus for strong summer light, drainage and bright winter rest above about 10°C.

Persian lime hybrid background and growth habit

Citrus × latifolia is treated as an artificial hybrid citrus and is commonly known as Persian lime or Tahiti lime. Botanical databases list a complex hybrid background involving Citrus hystrix, Citrus maxima, Citrus medica and Citrus reticulata, which reflects the layered ancestry behind many cultivated limes. In a container, it usually develops a sturdy woody framework with repeated flushes of leaf growth during bright warm periods.

Strong light supports flowering and fruit development. A summer outdoors helps the plant build energy in the leaves and wood, while a bright protected winter position above about 10°C helps it keep foliage and enter the next growing season in better condition.

Persian lime seasonal container care

• Light level: Give full sun during the outdoor growing season. Under cover, use the brightest possible position and supplement light if winter conditions are dim.
• Watering pattern: Water deeply, then wait until the upper part of the substrate has dried before watering again. Keep winter watering lighter in cool conditions.
• Persian lime mix: Use a citrus substrate with excellent drainage and lasting air space. Add mineral components if the mix compacts quickly.
• Cool-season rest: Move under protection before nights fall below about 10°C. A bright place around 10–12°C supports a slower, steadier winter rhythm.
• Leaf and fruit nutrition: Use citrus fertiliser from spring through early autumn. Include micronutrients, as potted limes can show yellowing when iron, magnesium or manganese availability drops.
• Pot management: Keep the plant in a drainage pot and repot gradually in spring when roots fill the container.
• Fruit set: Outdoor pollinators help in summer. Under cover, hand-pollinate fresh flowers if the plant blooms inside.
• Crown light: Remove weak inward growth and shorten long shoots after harvest to keep the tree open and easy to move.

Persian lime foliage and fruit checks

• Brown leaf edges: Review drying winds, salt buildup, irregular watering and heat behind glass.
• Heavy fruit load on a small plant: Check branch strain and watering consistency. Thin fruit if the young tree is carrying more than the crown can support.
• Yellow leaves after winter: Check root moisture, temperature and feed timing. Cold damp substrate can reduce nutrient uptake even when fertiliser is present.
• Pest marks: Inspect leaf undersides and stems for spider mites, scale, whitefly and mealybug before moving the plant under winter protection.

Persian lime peel oils and pruning caution

Peel, leaves and citrus oils can affect pets that chew lime material. Remove dropped fruit, loose leaves and cut stems where pets can reach them, and prune carefully around any thorny shoots.

Persian lime naming notes

The generic name Citrus is drawn from older Latin citrus naming. The epithet latifolia means broad-leaved, from Latin latus for broad and folium for leaf. Citrus × latifolia sits within Rutaceae and is widely known in horticulture as Persian lime or Tahiti lime. The multiplication sign marks its hybrid origin, while Lime identifies this product as a classic cultivated lime type.
