The Calamondin Tree (Citrus microcarpa or Citrofortunella microcarpa), also known as the calamansi or Philippine lime, is a small, ornamental citrus tree prized for its abundant, fragrant blossoms and vibrant, tangy fruit. This evergreen tree typically grows 6-10 feet tall, with a rounded canopy and glossy, dark green leaves. Its small, white flowers are highly fragrant and attract pollinators, often blooming year-round in warm climates.
The fruit is small, about 1-2 inches in diameter, with a thin, smooth skin that starts green and ripens to a bright orange. The tart, slightly sweet juice and aromatic rind are widely used in cooking, beverages, and marinades, particularly in Southeast Asian cuisine. Hardy and adaptable, the calamondin thrives in USDA zones 9-11 and can be grown in containers in cooler climates, provided it receives full sun and protection from frost. Its compact size, continuous fruiting, and ornamental appeal make it a favorite for home gardens and patios.
