Native to Alaska, Northern Yarrow is an erect perennial herb plant that produces one to several stems 6"-3' tall. Its leaves are evenly distributed along the stem, with the leaves near the middle and bottom of the stem being the largest. The leaves have varying degrees of hairiness, are 2-15" long, almost feathery, and arranged spirally on the stems. The plant generally has 3 to 8 ray flowers that are oval to round and disk flowers that grown in groups of 15 to 40. The flowers occur in a flat-topped cluster. Yarrow grows at low or high altitudes and commonly flowers from May through June. It's a frequent component in butterfly gardens and in the wild is frequently found in the mildly disturbed soil of grasslands and open forests. Medicinally, Yarrow has been used for centuries as a means of stopping the flow of blood from wounds. Blooming Time: July through August.
