Like love itself, flowers can be delicate and unique. And that is exactly why it’s so tricky to get both right.In our many years of testing for this guide, we’ve found that online flower delivery services are spotty. Think shipping delays and cargo jostling, extreme temperatures, and variability in when and how buds will open up. Plus, they’re not cheap.To that end, we think most people are best served by a reliable local florist who can deliver their own bouquets at peak bloom, without shipping complications or additional overhead. But if you don’t know of a local florist, online services can be a useful and convenient option.Over the years, we’ve tested more than a dozen services at different times of year, ordering various arrangements to ship to multiple locations around the country. Only one service — our top pick UrbanStems — has regularly met our standards for reliability, longevity, and a crowd-pleasing assortment of stylish bouquets. We also recommend Costco, a trustworthy option that offers more classic flowers for incredible value.
