Typically, it reaches a height of about 10 to 20 feet, showcasing a compact and bushy appearance. The tree is characterized by its elliptical or oval-shaped canopy, providing a distinctive silhouette.

2. Leaves: The leaves of the lemon tree are glossy, dark green, and ovate or elliptical in shape. They emit a fragrant citrus scent when crushed. The arrangement of the leaves is alternately positioned on the branches, contributing to the tree’s lush appearance.

3. Flowers: Lemon trees produce fragrant, white flowers with a five-petal structure. These flowers are often solitary or arranged in clusters, adding an aesthetic appeal to the tree when in bloom. The blossoms are not only visually pleasing but also play a crucial role in the lemon’s reproductive cycle.
