Asters belong to a much larger Composite family that includes Sunflowers. Characteristics are disk flowers surrounded by ray flowers. Some only have disks (thistles) others have only rays (dandelions). Asters can bloom at all different times of the year although most people are only aware of the ones that bloom in the fall. Idaho has several species that grow at different elevations; they include, but are not limited to, the Rough, Showy daisy, (Fleabanes) Elegant, Rocky Mountain and Leafy Aster. Wild asters can bloom purple, light blue to crème and the flowers grow in clusters or on single stems. They bloom from spring and through out the summer months with heights varying between 1 and 3 feet. They are common in our mountains and do quite well in challenging weather conditions. Asters make wonderful filler flowers for flowerbeds. They are an excellent choice for pollinator gardens located in sunny spots because they can grow in dry, rocky areas. Butterflies and bees are attracted to the colorful lavender/yellow combination.
