The fruits are small, roundish, reddish kernels containing small, black seeds. They ripen in the fall and stay in the tree for a long time through the spring.
It is widespread in southern Europe, southwest and central Asia. It grows in shrubs, in sunny to semi-shady areas, in moderately acidic soils, up to 1300 m above sea level. Propagation is done by seed and vegetative cuttings and root shoots. It tolerates poor soil, with large shoots of roots.
The fruits are harvested before they are fully ripe, dried and ground into powder, mixed with salt and other spices and used as a spice blend. The crushed fruits can be immersed in water for 10-15 minutes, the liquid is strained, sweetened and drunk like lemonade.
