Seeds, Yarrow Western (West Coast Seeds)

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.

Perennial.

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
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.
