Notes
Key lime (Citrus aurantiifolia) is a fruit for containers, food gardens, and low maintenance planting. It grows outdoors year-round in USDA zone 9 and warmer, down to about 20°F (-7°C). In colder areas, grow it as a houseplant or bring it indoors for winter. This plant likes full sun and average to moist, loamy soil. The evergreen leaves and fragrant flowers can show up in any season, and bees visit the blooms.
Pairs well with Guava, Lemon verbena, Rosemary, and Flowering banana.
