Centerpiece Tip: Cut the daffodils before their buds have opened for a long-lasting bouquet. You’ll enjoy watching their forms change, and the pussy willows will last just as long. Sprout fresh wheatgrass in a decked-out glass beaker. Note: Never eat flowers from a florist, a nursery, or a garden shop; they may have been sprayed. The same rule applies to flowers you find growing along a road or in a park.
