Hot-ticket restaurants? Check. Ultra-luxe bedding? Check. The latest battleground in the hotel wars: flower shops run by star petal-pushers. Guests at the Hotel Savoy ($$$$), in Florence, can jazz up their rooms with Sebastian Bierings’s modernist “sushi flower” arrangements (Lady Gaga and Elton John are fans). New York’s iconic Plaza Hotel ($$$$) recently welcomed a branch of the 100-year-old Gramercy Park Flower Shop, whose monochromatic, leaf-wrapped bouquets make perfect hostess gifts. In Menlo Park, California, Aili Ice has opened her first brick-and-mortar location at Rosewood Sand Hill ($$$$), showcasing designs that incorporate reclaimed wood. No wonder she’s the go-to florist of Silicon Valley VIP’s.
