Description

(Achillea ptarmica). The Pearl is a relative of common yarrow and was popular during the Victorian era. From pollinator attractor to medicinal plant and cut flower, this highly ornamental herb plays many roles. Plants reach 2 to 3 feet tall and produce gobs of cheerful white pompoms, which are alluring to many small pollinators. The Latin name Achillea is a reference to the historical medicinal properties of the plant, as it is said that the soldiers commanded by Greek mythological warrior Achilles used yarrow to treat their wounds. Also a versatile cut flower, it can be used fresh or dried as an everlasting.

Growing Tips: This yarrow variety thrives in full sun, with a preference for at least six hours of direct sunlight daily. It adapts well to various soil types, including poor soils, provided they are well-drained. Once established, it is quite drought-tolerant and requires minimal watering. To encourage continuous blooming and prevent self-seeding, regularly deadhead spent flowers.

Should I cover Double Diamond Pearl seed with soil?

No. Surface sow the seeds, gently pressing them into the soil, as light aids germination. The ideal germination temperature is 65 to 75°F, and seedlings appear in about 14 to 21 days. Sow indoors 6 to 8 weeks before your last frost and transplant outdoors after the last frost.

Will this yarrow come back year after year?

Once established it is quite drought-tolerant and needs minimal watering.
