PEARL YARROW: This Yarrow species is ideal for lining a pathway or in a drift as an accent to other colours.  Looks best when planted in groups or clusters.  Each plant is covered with a multitude of double white flowers, reminiscent of buttons.  Useful as a cut flower.  Plants grow to 60 cm (2’) and do best in full sun with well drained soils.  Seeds can be sown direct in late fall, early spring or started inside and transplanted out.  Cover the seeds with just a dusting of soil.  Will usually bloom the first year.  100 seeds.    P 401
