An English farmer may have answered the prayers of priests, by planting the first crops of natural confetti. Charles Hudson has devoted 16 acres of farmland to delphiniums which, when harvested and dried, will provide pink, purple, lavender and ivory petals to be scattered as a biodegradable alternative to paper confetti. (The Week, July 2003)
Charles Hudson's delphiniums - are here at The Real Flower Petal Confetti Company website.
These are the ones that grow in our garden.
If only people got married in churches nowadays instead of on hillsides, in public gardens, aloft in balloons, on the beach in Hawaii, at the bottom of somebody's orchard, underwater with flippers, at the zoo, or any number of other quaint places, then I might consider going into the organic confetti business!!!
