Small cranberry

About

The Small cranberry is an evergreen creeping shrub, with thin shoots that spread across a carpet of sphagnum moss. In Ukraine, its main reserves are in Polissia, while in the Carpathians and Prykarpattia, it is found rarely — only in acidic peat bogs, mainly oligotrophic ones, which are nourished by rainwater. The plant is light-loving and prefers cold and moist conditions.

The leaves are small, 5–16 mm, leathery, shiny, dark green on top and bluish below, with rolled edges. It blooms in May — June: on long thin flower stalks hang drooping pink flowers with backward-curved petals, resembling small lanterns. The berries are dark red, spherical or pear-shaped, 8–18 mm in diameter, ripening in September and can survive under snow.

The berries are edible and very sour. They are traditionally harvested in autumn to make drinks, jellies, and jams. However, bogs are fragile habitats: the area of cranberry bogs in Ukraine is decreasing due to drainage, and trampling damages the moss and peat. If the bog is located in a nature reserve or protected area of a national park, collecting berries there is prohibited.

Nearby, the small-fruited cranberry may grow, which has even smaller pointed leaves and berries only 4–6 mm. It is listed in the Red Book of Ukraine with a status of 'vulnerable', so if you are unsure which cranberry you are looking at, it is better not to collect the berries. Walk through the bog only on paths and boardwalks.

Where in the Carpathians

Orange — where naturalists recorded the species (GBIF, CC0/CC BY). It occurs only locally, so we draw no approximate range; a blank area does not mean it 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

Walk through the bogs only on paths and boardwalks: you can fall into the peat. Do not collect berries in reserves and protected areas of national parks.

Look-alikes — how to tell them apart

Protection and rules

Not listed in the Red Book of Ukraine (unlike the small-fruited cranberry). Collecting in reserves and national parks is prohibited; protect the moss — do not trample.
