Lime trees are small to medium-sized citrus trees known for their fragrant flowers and tart fruit. They typically grow to about 10 to 20 feet tall and thrive in warm, subtropical climates. The leaves are glossy and dark green, while the fruit is usually round and green, turning yellow as it ripens. These trees are commonly cultivated for their limes, which are used in cooking, beverages, and as a garnish. Lime trees prefer well-drained soil and full sunlight, making them popular in home gardens and commercial orchards. They can also attract beneficial insects like bees for pollination.
