Only in Paris would you find a florist’s shop that’s operated for over a century—Lachaume is the oldest in town. Proust was a fan back in the day, while today it’s Karl Lagerfeld who sings its praises. At their upscale address on Rue du Faubourg-Saint-Honoré, Caroline and Stephanie, who took over from their grandmother, continue her tradition while working with local producers to create bouquets that are much more attuned to the seasons. They’re also known for their dramatic, long-stemmed arrangements, and their incredible selection—they even have exclusives on certain varieties.
