'Olivia Orange' produces neatly mounded plants that are so smothered in hundreds of pumpkin-colored blooms that the foliage can scarcely be seen. It was bred for a long blooming season and sturdy stems that won't bend too much under the weight of the flowers. According to the National Chrysanthemum Society, there is evidence that mums have been cultivated since at least the fifteenth century B.C.E. in China. They have long been a popular subject in Chinese and Japanese art. Japan honors the flower with a National Chrysanthemum Day, also called the Festival of Happiness. The toothed leaves are very aromatic, with a spicy menthol scent, and have been used in herbal teas, along with the flowers. There are many classes of chrysanthemums, including single-flowered, decorative, anemone, and spider. This one is decorative and should be hardy if planted early in the season.
