Rowan

About

Rowan is one of the hardiest trees in the Carpathians. It grows from the foothills to the upper forest limit, extending to the polonynas along with juniper and common juniper, and is found on rocky slopes, clearings, and in spruce forests.

This small tree is 5–15 m tall or a shrub with smooth gray bark. The leaves are odd-pinnate, with 9–15 elongated serrated leaflets, turning yellow and red in autumn. In May – June, rowan blooms with flat white umbels that have a sharp smell.

The fruits are small, spherical, orange-red, gathered in large clusters. They turn red as early as August, but are traditionally harvested in autumn, after the first frosts. Raw fruits are bitter and astringent: they contain parasorbic acid, which irritates the stomach lining. Freezing, cooking, or drying destroys this substance, so rowan is considered conditionally edible.

In winter, rowan clusters are an important food source for birds: thrushes, waxwings, and bullfinches, as well as for martens and foxes. Therefore, when collecting berries, leave some on the tree. There are no dangerous lookalikes among rowan trees, but the red berries of red elderberry, which grows nearby, have poisonous seeds.

Where in the Carpathians

The map shows where naturalists recorded the species (GBIF, CC0 and CC BY records), not every place it lives. The Ukrainian Carpathians are less studied, so a blank area does not mean the species is absent.

When to see it

From naturalists’ observations in the Carpathians (iNaturalist, research grade): the darker the cell, the more often the species is seen that month.

Safety

Raw berries are bitter and irritate the stomach; they should only be consumed after freezing, cooking, or drying. Do not give unfamiliar berries to children and teach them not to taste anything in the forest without adults.

Look-alikes — how to tell them apart

In folk tradition

The fruits are traditionally cooked into jams, jellies, and compotes after frost, and dried for tea.
