Back to Full ListCommon Tansy
Latin Name: Tanacetum vulgare
Identification
Flower: Small, button-like, yellow flowers that bloom in late summer through early fall.
Leaves: Deeply lobed, fern-like, and aromatic when crushed.
Stems: Erect, rigid, and slightly woody, growing up to 1.5 meters tall.
Growing Environment: Prefers well-drained soils in fields, roadsides, and disturbed areas.
Growth Habit: A perennial herb that forms dense colonies through both seed dispersal and creeping rhizomes. It has a tall, upright growth habit, often forming large clumps of erect stems topped with yellow flowers. In situ, common tansy appears as a large, bushy mass with clusters of yellow flowers that stand out against the dark green, fern-like foliage.
Impacts on Environment
Impacts: Common Tansy is highly invasive, particularly in disturbed areas where it can out-compete native vegetation.
