@parisgardenstory: Why are Paris streets lined with trees? Paris didn’t always have tree‑lined boulevards. Regular street planting began in the 1600s and became systematic under Baron Haussmann in the 19th century. Plane trees and horse chestnuts were chosen for their height and shade, but species selection has always been complicated. Today, the city works to avoid monoculture and diversify its street trees as pests and disease affect older plantings. Paris’s street trees aren’t random: they’re designed. #ParisTrees #ParisHistory #UrbanDesign #StreetTrees
