Achillea Millefolium Occidentalis Seeds – 500 Western Yarrow Native White Wildflower

Achillea millefolium var. occidentalis, commonly known as Western Yarrow, is a hardy native perennial wildflower valued for its flat-topped clusters of small white flowers and finely divided, fern-like foliage. This western North American native brings a natural, meadow-like feel to pollinator gardens, wildflower plantings, and low-water landscapes. Its long bloom season and drought tolerance make it a dependable choice for gardeners seeking a resilient, wildlife-friendly plant.

Western Yarrow is well suited to native plant gardens, xeriscapes, prairie restorations, and cottage-style borders. The nectar-rich flowers attract bees, butterflies, and other beneficial insects, while the textured gray-green foliage adds interest even when the plant is not in bloom. It can be grown from seed and established in a variety of sunny, well-drained sites.

Planting & Care

Western Yarrow seeds can be sown directly in the garden or started indoors. For best results, sow seeds on the surface of a well-drained seed-starting mix and press them lightly into the soil, as light aids germination. Keep the medium consistently moist but not waterlogged. Germination may be slow and uneven; patience is often required. Once seedlings are large enough to handle, transplant them into individual pots or harden them off for outdoor planting.

In the garden, choose a sunny location with well-drained soil. Water young plants regularly during their first season to help them establish. Once established, Western Yarrow is quite drought tolerant and generally needs only occasional watering. Deadhead spent flowers to encourage additional blooms and prevent unwanted self-seeding if desired. Divide clumps every few years to maintain vigor.
