When herb gardens overflow with more than is needed in any kitchen, why not use the extra yield in a fragrant centerpiece? Mix shapes and textures, and add color with edible flowers and herb blossoms. This arrangement, which includes dill, rosemary, mint, basil, thyme, lavender, nasturtiums, and flowering herbs, sits in a high-sided bowl; a smaller bowl within keeps the stems in place. But a vase, pitcher, or jar would work just as well.
