The Thornless Key Lime (Citrus aurantiifolia) is a compact, easy-to-grow citrus tree prized for its smooth, juicy limes and nearly thorn-free branches. This everbearing variety produces small, aromatic fruits with a classic tangy flavor, perfect for pies, drinks, marinades, and fresh garnishes. Its glossy green foliage and fragrant white blossoms make it both ornamental and productive. Ideal for container growing in cooler regions, it thrives in full sun and provides a steady harvest of fresh, homegrown limes.
