As of the printing of these stamps, the names were accurate. Cacti also have common names, with some plants having several different names in popular use. Cacti are flowering perennial succulents in the plant family Cactaceae. Though experts debate exact numbers, more than 1,500 species are known. Almost all cacti are native to the Americas, ranging from British Columbia and Alberta in Canada to the southern regions of Argentina and Chile. The southwestern U.S. and Mexico are home to the greatest variety and abundance of cacti. Several botanic gardens in the U.S. showcase the wide variety and stunning beauty of these plants. When the cacti are in bloom, visitors are presented with a vivid - and surprising - floral display. Cactus flowers generally occur singly, although many separate blossoms might appear on a plant at the same time. Flowering occurs at different times of the year and even different times of the day or night depending on the species. Most cactus flowers are large and flamboyant, with colors of white, red, pink, orange, or yellow. Some flowers are also richly scented, and the nectar and colors attract pollinators such as bats, bees, and birds. Cacti are among America's most popular houseplants. Most cacti grow very slowly, and they are tough, adaptable, and low maintenance. They are also favorites for rockeries and desert and exotic gardens. When they bloom, their flowers put on a show that compares in beauty with any flower in the garden.
