Mature Tansy Ragwort plants can be easily spotted because of their bright yellow daisy-like flower and ragged leaves. Plants generally grow between 0.3 m to 1.2 m in height, although in ideal conditions they can reach heights of nearly 2 m.

Numerous stems can grow from one central root, with a cluster of flowers growing on top of each stem.

Look-alike weeds:

There are two weeds found in the Fraser Valley that are commonly mistaken for Tansy Ragwort, however, they do not share the same invasive characteristics.

• Common Tansy has a button-like yellow flower with no distinct petals.

• St. John's Wort has a yellow flower with only five petals, and a distinctive centre with multiple antennae-like structures.
