Ragwort rosette

Rosette growth can vary greatly. As the rosette develops, the leaves look irregular with jagged edges. Rosettes are often dark green but can be tinged with purple.

Ragwort roots

Even at rosette stage, roots are numerous, relatively thick and quite tough.




Ragwort seedlings appear from autumn to June and are usually spotted when around 10-15mm high, although they often go unnoticed until they reach rosette stage. They have a spade-shaped leaf that is notched at the top.

Second Year Growth: Plant Stage

Ragwort flowers

Seeds ripen in July/August and are normally shed from September. One plant can produce thousands of seeds, which can lie dormant for years.



Ragwort leaves

Leaves are dark green and quite tough. They may be sparsely hairy on the lower side. Leaves are deeply divided with irregular, jagged edges.


Ragwort stems


Stems are tough and often tinged red near the base, but are brighter green and branched near the middle.
