An American tree turns the best colour in central Prague, on an island where Bohemian archers used to practise.
Northern Red Oak
Quercus rubra
Northern red oak is the oak of eastern North America, and Europe planted it for one thing: nothing native turns that colour in autumn. We map 33 of them, in 24 cities.
Brussels Environment's own walking route through the Parc d'Egmont gives up on describing its red oak and tells you to come back in autumn instead. At home the old ones are older. In 2020 Toronto's city council bought a private house on Coral Gable Drive and tore it down to save Zhelevo, an oak of roughly 300 years left from the savannah along the old Carrying Place trail. Toronto's official tree, in Kew Gardens, is 5.3 metres round with one limb sagging to the grass. In Europe, Prague's stands on the island where the city's archers used to practise, and the Baarn oak, roughly 175 years old, wears a ring carrying words the municipality asked its residents to write in 2021.
