ROADWEEDS OF THE UPPER PENINSULA

The bright yellow flower heads of tansy are a common sight in late summer and early fall.  These tall plants are easily seen.  The compound leaves are quite aromatic and have a very lacy appearance.   New plants can sprout from the stout, spreading roots.  Occurring naturally in the wild but originally from Eurasia, tansy was likely an escape from early American gardens.  It still is part of many flower garden in Michigan.  About the only thing you might confuse tansy with is wild parsnip.  However, wild parsnip is usually done blooming by the time tansy begins.  There is a native tansy that grows in sand dunes around the Great Lakes (T. huronense).
