Fun Facts
- 🌱 Rowan trees are deeply embedded in European folklore and mythology, particularly in Celtic and Norse traditions, where they were believed to offer protection against evil and were planted near homes and sacred sites.
- 🌱 The scientific name 'aucuparia' comes from the Latin 'auceps' (fowler/bird-catcher), referring to the tree's use in bird trapping—birds were so attracted to the berries they were easily caught.
- 🌱 Rowan trees can live 100-200+ years and are remarkably cold-hardy, thriving at high altitudes and latitudes where few other trees survive, making them invaluable for difficult northern landscapes.
