Showy Aster is a native perennial wildflower recognized for its tall stems topped with clusters of light purple blooms. Blooming from late summer into autumn, it provides an important late-season source of nectar and pollen for pollinators. It also produces seeds that are eaten by birds, extending its value to wildlife beyond the flowering season.

Drought tolerant once established, Showy Aster grows well in urban, rural, and disturbed sites. With its mix of ecological value and ornamental appeal, it is ideal for pollinator gardens, naturalization projects, and ecological restoration.

Nuttall’s Sunflower is a native perennial wildflower known for its bright, golden-yellow blooms. Flowering from mid to late summer, it offers a late-season nectar source for various bees, butterflies, and other pollinators, while the seeds provide a fall food source for birds. The upright growth habit adds structural height and visual variety to your landscape.

Nuttall’s Sunflower can be found growing in moist to wet meadows, prairies, and open spaces. It can spread quickly via underground rhizomes, making it ideal for large-scale plantings. It is well-suited for naturalization, soil stabilization, riparian zones, and wetland restoration projects. If planting in smaller urban yards or gardens, extra care and maintenance will be required to limit its spread.
