100 Arnica Chamissonis Seeds – Native Yellow Wildflower for Pollinator Gardens

Arnica chamissonis, commonly known as Chamisso arnica or meadow arnica, is a native perennial wildflower that brings bright, daisy-like yellow blooms to gardens and naturalized landscapes. This hardy plant is native to western North America and thrives in moist meadows, woodland edges, and along streambanks. Its cheerful flowers appear from early to midsummer, attracting bees, butterflies, and other beneficial pollinators. Arnica chamissonis is an excellent choice for pollinator gardens, wildflower meadows, rain gardens, and native plant landscapes. It also works well in perennial borders where its vibrant yellow flowers provide long-lasting color.

Planting & Care

Sow Arnica chamissonis seeds indoors 6-8 weeks before the last frost or directly outdoors in fall or early spring. Lightly press seeds into the soil surface; do not cover deeply, as light aids germination. Keep soil consistently moist until germination, which typically occurs in 14-30 days at 65-70°F. Once seedlings have several true leaves, transplant them outdoors after the danger of frost has passed, spacing them 12-18 inches apart in a sunny to partially shaded location with moist, well-drained soil.

Water regularly to maintain even moisture, especially during dry periods. Mulch around plants to conserve moisture and suppress weeds. Deadhead spent flowers to encourage additional blooms and prevent self-seeding if desired. Divide clumps every 2-3 years in early spring or fall to maintain vigor. Arnica chamissonis is generally pest-free and deer-resistant, making it a low-maintenance addition to native plant gardens.
