Blue Marzano.

An extraordinarily beautiful variety that makes anyone walking by slow down to look). The bush is medium-tall, sturdy, about 1.4 m (4.5 ft) outdoors in open ground. Good yield, mid-season ripening. The fruits are plums with a little beak, almost completely flooded with anthocyanin. Weight is 50-80 g (1.8-2.8 oz). You can’t immediately tell what color they are. But the color of the fully ripe fruits is orange-red. The taste is strongly spicy, sweet and sour.
