But vases aren’t a one-size-fits-all deal: The best vase depends on the types of flowers and arrangements you’re working with. Narrow mouthed vasesShape: medium-size vase that tapers off to a small openingPerfect for: Single stem large blooms and sparse farmers market bouquets. While narrow-mouthed vases can sometimes restrain multistemmed flower arrangements, they are quite well-suited for a single stem with a large bloom, like sunflowers or chrysanthemums. “A vase that is taller than it is wide is more useful for your average person who doesn’t want to spend a gazillion dollars on flowers,” Patterson notes. Bud VasesShape: Small with little openingPerfect for: individual flowers, wispy stemmed wildflowersJust because flowers came together doesn’t mean you have to keep them together.
