The Lisbon lemon tree, scientifically known as Citrus limon 'Lisbon,' is a popular variety of lemon tree that originated in Portugal. It is a small to medium-sized evergreen tree with a dense and bushy growth habit. The tree typically reaches a height of about 10 to 20 feet at maturity.
 
The foliage of the Lisbon lemon tree consists of glossy, dark green leaves that are ovate or elliptical in shape and have a slightly serrated edge. The leaves emit a citrusy fragrance when rubbed or crushed, adding to the overall appeal of the tree.
 
The fruit of the Lisbon lemon tree is the classic lemon that is widely recognized and used in culinary applications. The lemons are medium to large in size and have a bright yellow, smooth, and slightly thick skin. The pulp inside the fruit is juicy, acidic, and rich in vitamin C. The Lisbon lemon is known for its tangy flavor, which is a balance of sweetness and acidity, making it versatile in cooking, baking, and as a garnish.
 
The tree produces a profusion of lemons throughout the year, with a peak harvest period during the winter months. The fruits are typically harvested when they have reached full maturity and are fully yellow.
 
Lisbon lemon trees are well-adapted to warm climates and are commonly grown in Mediterranean and subtropical regions. They are popular choices for home gardens, orchards, and commercial citrus groves due to their reliable fruit production, adaptability, and culinary value.
