Grapefruit trees are evergreen trees that belong to the citrus family, known scientifically as Citrus × paradisi. They can grow up to 15-20 feet tall and have glossy, dark green leaves. The trees produce large, round fruits that can be yellow, pink, or red, depending on the variety. Grapefruit trees thrive in warm, subtropical to tropical climates and require well-drained soil and plenty of sunlight. These trees typically start bearing fruit within 3 to 5 years after planting. Grapefruit is rich in vitamins, particularly vitamin C, and is often enjoyed fresh or as juice. They are also known for their slightly bitter and tangy flavor, making them a popular choice for healthy diets.
