Rowan (Sorbus aucuparia) is a species of deciduous and perennial tree in the Sorbus genus of the rose family. Rowans grow in nearly all of Europe. In Estonia, rowans are common in the edges fields and underbrush and they grow to be 10–15 high and 30–50 thick. Due to its beautiful flowers and fruits, rowans are grown as decorative trees; some of their fruit are edible and healthy; their timber is flexible and strong, and therefore perfect for carpentry. Rowans do not shed their berries in the fall, so they are important sources of food for birds in the winter when it is snowing. The stamp has a face value of 1.40€
