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.

The Eastern Redbud is known for the pea-like pink buds that emerge in clusters on the bark, embellishing the tree in stunning flowers. They have a longer bloom time, sometimes for two to three weeks before the heart-shaped leaves emerge for the summer. Inedible pods emerge that turn brown in the summer, this tree is a part of the bean family.

Native to the Eastern North America. The Eastern Redbud can tolerate acidic and alkaline soil. Plant this as a beautiful understory species or shaded residential yard or garden. The bright pop of color will make an attractive ornamental tree.
