The Desert Lime while has been extensively cleared, from some regions as a consequence of agricultural practices, is comparatively common fruit tree.

Citrus glauca foliage is greenish-grey, with spiny stems with irregularly distributed thorns. Leaves are rounded, up to 5cm long and 0.5 cm wide. Flowers are white or greenish in color, 10 mm across, born in late winter and spring, followed by light-green/yellow fruits.

Desert Lime Fruit

Desert Lime fruits are globular in shape and about 15 mm diameter, edible with a strong lime flavor. The fruit is a highly valued bush food employed in a range of products, including marmalade, beverages, and glazed fruit. It is by and large wild harvested from surviving bush land parts.

Desert Lime Propagation Methods

Tree propagation is achievable from seed but cuttings might be slow to strike. Grafting or budding onto other citrus stocks has evidently been successful. Commercial cultivation of the Desert Lime is commencing to slowly reduce the reliance on wild harvested product. The plant has a suckering habit which may require to be checked in cultivation.

Research indicates that Citrus glauca is one of the most resilient Citrus species, being relatively heat, drought and cold tolerant. Hence the species is potentially significant for Citrus breeding programs, and readily hybridizes with a lot of common Citrus species. Gitrus glauca is a member of the Rutaceae family the genus Citrus.
