Features and characters of the individual

This narrow-leaved ash grows in the public garden of La Grotte de Notre Dame de Lourdes in Jette. The tree’s silhouette is curious. Its grey/brown, deeply fluted bark attracts attention. At 50 cm from the ground, its huge trunk suddenly swells – evidence of where it was grafted years ago. Unless, perhaps, these swells are relics of its healing past? In many ancient cultures, ash trees are sacred and mythical, with the power to absorb fevers and the pain of the sick. Yggdrasil, the cosmic ash tree in Scandinavian mythology, could even cure snake venom. In this garden, visitors and pilgrims come to see the grotto and the other symbols of Catholicism. Sadly they rarely come to visit this ash. On the other hand, even today, ash is a species that continues to be recognised for its numerous medicinal properties, particularly its analgesic and febrifuge effects.
