As they contain natural calcium good for application and emit strong flavour, the fruits can be processed into various kinds of foods in the form of juice, wine, vinegar and milk. These foods can also be canned.

It presents peculiar natural landscape, when planted in several places in a group of 10 to 20 in combination with green plants.
