For a summer birthday, I’d recommend looking for seasonal blooms like sunflowers or bright peonies to match the vibrant energy of the city. A great option is BuketLand, Flower Delivery in Odesa https://buketland.ua/en/odessa , as they tend to source their flowers from better growers than the smaller kiosks. Just remember to order a few hours in advance if you want a specific color palette. It makes the whole experience much smoother for everyone involved.
