Description Mexican Key Lime—also known as West Indian or Bartender’s lime—is the traditional lime behind classic pies, marinades, and cocktails. Unlike larger Persian limes, Key limes are small, thin-skinned, and intensely aromatic, delivering sharp acidity and concentrated flavor. This thornless selection preserves the authentic Key lime character while eliminating the sharp thorns common to standard trees, making it a far more pleasant choice for home growers, patios, and container culture. Fruit is typically harvested green for peak acidity and may turn yellow if allowed to fully mature. Overview Classic Mexican/Key lime with bright, intense acidity. Small fruit with thin rind and highly aromatic juice. Thornless growth for easier maintenance and harvest. Often seeded (not a seedless lime). Self-fertile. Growing Details Latin Name: Citrus aurantiifoliaSite and Soil: Full sun; well-drained soilRootstock: 1-gallon trees on Flying Dragon; larger sizes on C-35Hardiness: Very frost sensitive; best suited to USDA Zones 9–11Bearing Age: Often fruits immediately; grafted trees may produce in their first seasonSize at Maturity:• Flying Dragon: Typically 6–8 ft tall and wide• C-35: Typically 10–12 ft tall and wideNote: Trees grown in containers remain smaller and are easily maintained with pruning.Bloom Time: Spring, with additional blooms in warm, stable conditionsRipening Time: Fall into winter; fruit may be held longer in mild climatesPollination Requirements: Self-fertileSeed Content: Often seededPests & Diseases: Similar to other citrus; good airflow and drainage reduce issues Additional Notes Grower’s Insight: Key lime trees often carry flowers, immature fruit, and harvest-ready limes at the same time, allowing selective picking over an extended period in warm conditions. Regional Insight: Performs best in true citrus climates (Zones 9–11); container culture allows successful growing outside these zones with winter protection.
