Purple Prairie Clover is a native perennial wildflower known for its striking purple blooms. The flower heads grow as dense spikes on tall stems, with each flower head containing many tiny blossoms. Blooming for 4–6 weeks in the summer, it attracts a variety of pollinators, including bees and butterflies.

The high protein content of the Purple Prairie Clover makes it excellent forage for wildlife and birds like to feed on its seeds. As a nitrogen-fixing plant, it enriches the soil, improving fertility and benefiting nearby vegetation. These ecological contributions make it a great choice for pollinator gardens, prairie & rangeland restoration, naturalization, and re-vegetation efforts.

This drought and heat-tolerant plant thrives in various soil conditions, including rocky soil, making it remarkably easy to grow in challenging environments.

Black-Eyed Susan is a striking native wildflower known for its bright yellow, daisy-like flowers with dark center disks. With deadheading, the plant can bloom for an extended period, from mid-summer to early fall. These cheerful flowers attract a variety of pollinators, including bees and butterflies. Adding to its ecological value, the plant also acts as a host for the Wavy-Lined Emerald Moth (Synchlora aerata) and the Silvery Checkerspot (Chlosyne nycteis) butterfly.

While it is typically a short-lived perennial or biennial, the plant freely self-seeds. This allows it to persist in the landscape, particularly in natural areas where it can spread and establish itself. This plant is drought-tolerant, salt-tolerant, and deer and rabbit-resistant, making it ideal for challenging environments. The Black-Eyed Susan is well suited to wildflower gardens, pollinator gardens, as well as slopes, banks, and naturalized areas.
