Meet the tree

Diamante is a citron closely associated with Calabria’s Tyrrhenian coast and the Riviera dei Cedri. Its name recalls the town of Diamante, in the province of Cosenza.

The villa document describes its long-standing cultivation along this coastal territory and its importance to local agricultural identity. It also recounts the careful selection of Calabrian citrons for the Jewish festival of Sukkot.

The fruit is typically large and elongated, with a yellow rind at maturity. Compared with more knobbly citrons, its surface is relatively smooth, sometimes with gentle ribs.

Aromatic peel makes it valuable for candying and traditional confectionery. The interest of this tree extends beyond its fruit: it brings agricultural practice, local heritage and ritual use together in a living plant.
