**🌿 Plant Identification Series: Yarrow**
Once you learn Yarrow, you’ll start seeing it everywhere.
But as with any wild plant, look at the whole plant and make sure several features agree.
🌿 **Leaves** – One of Yarrow’s best identification clues. The leaves are deeply divided, soft-looking and almost feathery or fern-like. This delicate appearance is behind its old name, **“thousand-leaf.”**
🌿 **Stem** – Upright, firm and usually slightly hairy, with leaves growing alternately up the stem.
🌼 **Flowers** – What looks like one flat cluster is actually made up of many tiny flower heads. Wild Yarrow is most commonly white to creamy-white, although pale pink can occur.
👃 **Scent – a useful clue!**
Yarrow has a **strong, distinctive herbal aroma**—green, aromatic and slightly medicinal, with a somewhat bitter or camphor-like character.
Once you become familiar with it, the smell can be one of those clues that makes you think, *“Yep, that’s Yarrow.”*
Just remember: **scent supports an identification; it shouldn't make the identification on its own.**
🌱 **Growth Habit** – Often grows in patches in sunny, open areas: fields, roadsides, trails, lawns and disturbed ground.
📅 **Season** – In Canada, Yarrow commonly flowers from early summer well into fall.
# # # ⚠️ Look-alikes matter
Yarrow belongs to the **Asteraceae family**, but its white, flat-topped flower clusters can superficially resemble plants from the **carrot family (Apiaceae)**.
That distinction matters because the carrot family includes some **highly toxic plants**, including poison hemlock and water hemlock.
Yarrow’s **finely divided feathery leaves, clusters of many tiny flower heads, usually hairy solid stem and distinctive herbal scent** give you several clues to work with.
**Never identify a wild plant from one photograph, one flower, or one characteristic.**
Look at the leaves.
Feel and examine the stem.
Look closely at the flowers.
**Smell the plant.**
Notice where it is growing.
Check the season.
