CULTIVATION _ Asters are most often used now as filler in bouquets and as a delicate accents in gardens. They grow best in rich, wet soil in direct sun _ partial shade, and should be thinned and replanted every two years. Because Asters grow in thick bunches, they can be separated and replanted in gardens in the spring. Asters bloom from mid summer _ early fall and are a perfect choice for a fall wedding bouquet.
I have noticed that western style gardens _ such as those seen in big castles, for example _ characterize themselves by man_made forms that generally follow symmetric patterns. In contrast, Japanese gardens, while also man_made, always try to recreate lifelike landscapes, by using not only botanical elements but also water, gravel, rocks and other natural components. In a similar manner, when compared to western floral arrangements, Ikebana compositions also have a stronger emphasis in reproducing natural settings.
