Guelder rose

Scientific name: Viburnum opulus
Common name: Guelder rose

Belonging to the Caprifoliaceae, the snowball tree can reach up to 5 m in height. It is a shrub widespread throughout most of Europe, as far as northern Asia. It is found in floodplain forests, woodland edges and shrubs. With its extensive root system, it lends itself well to bank consolidation. The opposite 8-10 cm long leaves, with 3-5 lobes, resemble those of some maple species, but have glands on the petiole. It produces small fleshy red fruits. In summer they may appear pitted as they are gnawed by yellow-green larvae with black spots from the Viburnum galeruca. The highlight are the very white flowers, grouped in many spheres, hence the other name "snowball".

In the Celtic calendar, Viburnum opulus is the sacred tree related to Ngetal, the period from October 28 to November 24. According to tradition, those born during this period have hidden forces and are animated by secret motives, so they are advised to use their investigative skills wisely.

Because of its rapid growth, it is perfect for environmental restoration efforts, reconstitution of natural forests and formation of field hedges in wet soils. The showy white flowers make the snowball tree suitable for ornamental purposes. Its red drupes are a source of food for some birds but are poisonous to humans. When dried, a carmine ink can be obtained.
