Citrus hystrix - Thai Lime

Thai or Kaffir Lime is a medium-sized shrub that is commonly grown for its edible qualities. It produces green oval fruit which are usually ready for picking from early spring to late winter. The fruits have a tart taste.

Features & Attributes

Thai Lime features showy clusters of fragrant white star-shaped flowers with buttery yellow eyes at the ends of the branches from early spring to late winter. It has attractive dark green evergreen foliage. The glossy oval leaves are highly ornamental and remain dark green throughout the winter. It produces green berries from early spring to late winter.

This is a multi-stemmed evergreen shrub with an upright spreading habit of growth. Its average texture blends into the landscape, but can be balanced by one or two finer or coarser trees or shrubs for an effective composition. This is a relatively low maintenance plant, and is best pruned in late winter once the threat of extreme cold has passed. It is a good choice for attracting birds, bees and butterflies to your yard. It has no significant negative characteristics.

Planting & Growing

Thai Lime will grow to be about 5 feet tall at maturity, with a spread of 4 feet. It has a low canopy, and is suitable for planting under power lines. It grows at a slow rate, and under ideal conditions can be expected to live for 50 years or more.

This plant is typically grown in a designated edibles garden. It does best in full sun to partial shade. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This species is not originally from North America.

Thai Lime is a good choice for the edible garden, but it is also well-suited for use in outdoor pots and containers. With its upright habit of growth, it is best suited for use as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. It is even sizeable enough that it can be grown alone in a suitable container. Note that when grown in a container, it may not perform exactly as indicated on the tag - this is to be expected. Also note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
