Achillea millefolium var. occidentalis. This is an important native North American wildflower and pollinator plant. It thrives particularly in recently disturbed soil. Because of this feature, Western Yarrow seeds are especially useful for planting around work sites, septic berms, or roadside areas. This variety grows 25-90cm (10-36") tall, with densely hairy, lacy, fern-like leaves. It has an extended bloom period from May to September, and is very attractive to beneficial insects, including predatory wasps, ladybird beetles, and hover-flies. Western Yarrow is also highly drought-resistant, so it's excellent for xeriscaping and erosion control. It is widely used in New Zealand as pasture.

Timing

Sow indoors 8-10 weeks before planting out after the last frost date. Transplant or direct sow in early spring or early autumn. Optimal soil temperature for germination: 15-18°C (60-65°F). Seeds can take 10 to as long as 100 days to sprout, so be patient. Bottom heat speeds germination.
Starting
Starting
Sow on the surface of the soil, under bright lights if starting indoors. Transplants can go out while the soil is still cool and there is still some risk of light frost. Space transplants at 30-60cm (12-24″) apart.

Yarrow is a tough plant that is suitable for xeriscaping, and it will adapt to pretty much any soil. For best results, grow in a loamy, well drained soil with a pH of 5.5 to 7.0. Divide plants every 3-4 years. Cut plants to ground level in autumn.
West Coast Seeds is a family-owned company that embraces an organic lifestyle. A group of imagination catalysts and passionate educators, dedicated to producing products and services that better the environment. As part of our mission to repair the earth, we aim to inspire and empower people to take responsibility for the state of the planet. For us, organic is about much more than saying no to chemicals, it is about saying yes to building a healthy soil for the future.
For over 35 years, we have upheld our strong reputation as a leading seed supplier, seeking out the highest quality untreated seeds for organic growing and putting them through rigorous independent testing. We built our company on the exchange of generational wisdom in a masterclass community of newbies and masters alike. Our world may have changed, but our commitment to our people, our customers, and our planet has not.
We’re a values-based business that has blossomed into a lifestyle ethos, with products that support seeders, feeders, keepers, and the tiniest of creepers. Our mission? To mobilize the next generation of gardeners with products that nourish soil and grow vigorous, sustainable gardens. We believe all plants should be grown without the use of chemicals, and that the seeds we supply are an important component of regenerative gardening.
We don’t just offer seeds, we offer experience, insight, and understanding. From timeless garden wisdom to new tech know-how, this is learning on the job: knowledge gleaned not from the pages of a book but from burying our fingers in the soil. We test, experiment, observe and adapt, never happier than when we get to share what we’ve learned with others.
Gardens don’t just grow seeds. They grow minds and imaginations, people and communities. Our vision encompasses both the micro and the macro. We eat locally, protect pollinators, teach people to grow from seed, and support regional biodiversity. We think big but act small and deliver unexpected impact — always with community and purpose.
At West Coast Seeds we believe in the power of small and that little can be large. Like the tiniest seed germinates to evoke incremental change with massive potential, so to can our community of gardeners and growers together. Gardeners are the earth’s stewards, planting seeds of creative declaration. The soil provides the canvas, we provide the seeds.
