To create these bold yellow-and-white centerpieces, New York City floral designer Naomi deManana combined jonquils, ranunculus, tulips, and sweetpeas, placing flowers in single-variety mini bunches before combining; this highlights the lush textures of each type. Opaque vases mean no stressing about the look of the stems. A band of thick yellow ribbon around each vase, plus lengths of it across each place setting, extend the crisp color scheme. Vase, CB2. 38-millimeter ribbon, Mokuba New York. "Edge" wine glasses, Crate & Barrel.
