Historically, purple and violet have been associated with the color of royalty. These colors gained high status because the original dye was so rare and expensive that it was only accessible to royal persons. Add a splash of this dignified color to your home or office with the Artichoke Bouquet 16 in. Dried Floral Wreath. This arrangement features preserved purple artichokes with bundles of green hydrangea blooms, green fern, natural phalaris, preserved purple myrtle, nigella pods and salal leaves.
