The Eureka lemon tree, scientifically known as Citrus limon 'Eureka,' is a widely cultivated lemon variety that is valued for its abundant fruit production and easy cultivation. It is a medium-sized evergreen tree with a spreading growth habit. At maturity, it typically reaches a height of about 10 to 20 feet.
 
The foliage of the Eureka lemon tree consists of glossy, dark green leaves that are oval or elliptical in shape and have a slightly serrated edge. The leaves emit a pleasant citrus fragrance when touched or brushed against.
 
The Eureka lemon tree produces medium to large-sized lemons with a classic lemon shape. The lemons have a bright yellow, smooth, and slightly thick skin. The pulp inside the fruit is juicy, acidic, and rich in vitamin C. The Eureka lemon is known for its tangy flavor, which is a balance of sourness and sweetness, making it suitable for a variety of culinary uses, including cooking, baking, and garnishing.
 
One notable characteristic of the Eureka lemon tree is its ability to produce fruit nearly year-round. It may have multiple harvest periods throughout the year, ensuring a steady supply of lemons. However, the main harvest period typically occurs in the winter months.
 
Eureka lemon trees are adaptable and can thrive in a range of climates, making them suitable for both subtropical and Mediterranean regions. They are popular choices for home gardens, orchards, and commercial citrus groves due to their reliable fruit production, versatility, and hardiness.
