The U.S. Postal Service celebrates spring and Americans’ love for tulips with the issuance of Tulip Blossoms Forever stamps..Each fall, millions of gardeners bury bulbs in the earth, eagerly anticipating the rewards that springtime will bring. Months later, thick green leaves poke through the soil, soon revealing their treasure: tulip blossoms in spectacular variety from prim to ostentatious..A member of the lily family (Liliaceae), the tulip (genus Tulipa) originated as a wildflower in Central Asia. Dutch immigrants brought the first tulip bulbs to America hundreds of years ago. Today, we import more than 1 billion bulbs per year..These new stamps from the Postal Service feature closeup views of 10 different tulips in a rainbow of colors. Each flower fills almost the entire frame of the stamp, with just the top of the stem showing. Art director Greg Breeding designed the stamps with existing photographs by Denise Ippolito..Tulip Blossoms will be issued as Forever stamps and will always be valid for the current domestic 1-ounce letter postage price.
