History & Description
Origin
Dioscuria is a lemon cultivar offered by French specialist nurseries, which describe it as an original lemon halfway between a lemon and a lime. Its name recalls Dioscurias, the ancient Greek colony on the Black Sea coast at present-day Sukhumi, in Abkhazia, but the exact origin of the variety is not documented.Tree description
The tree is vigorous and fairly productive. Nurseries rate it as more cold-tolerant than many classic lemon trees, at about 16 to 18°F (−9 to −8°C).Fruit quality
The fruit is elongated and generally seedless, with handsome segments in cross-section. The flesh is slightly acidic, with notes that recall the Meyer lemon, and the very aromatic zest evokes a blend of lime and mandarin. Nurseries give a harvest from December to January.Flavor and ornamental interest
Its taste, between lemon and lime, makes it a versatile kitchen lemon for juice, dressings, fish and drinks, and its fragrant zest is the main attraction for desserts and cocktails. It is a collector's lemon for gardens where the classic lemon tree struggles with winter.
