Asters are hardy perennials that bloom late summer until the first hard frost. Many asters are native to Nebraska and a late-season source of pollen for migrating monarchs, other butterflies, moths, bumblebees, solitary bees, honey bees and soldier beetles.
Asters are easy to grow and look great in a mass planting. They can be planted with other native plants like purple coneflower, coreopsis, black-eyed Susan and native grasses.
The main plant disease is powdery mildew. It causes a whitish growth that appears on leaves. To reduce the chance of this disease, grow asters in full sun and space the plants, so they are not crowded.
