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.
You could create an arrangement for any size vase, the larger the vase, the more flowers and greens to use. For Christmas time, use red, white and maybe even green flowers (like green button mums). Also choose from a variety of greens and evergreens out there. Accent a red rose in a bud vase with some baby's breath and cedar. Deep red alstroemeria are especially beautiful.
