Dandelion
HarmlessTaraxacum officinale
How to recognise it
A rosette of jagged, backward-pointing 'lion's tooth' leaves, a single hollow stem with milky sap, a bright yellow flower head, and the familiar white seed clock.
Is it dangerous?
Harmless, and edible to many — but it has lookalikes and roadside plants may carry pollutants, so don't eat foraged plants identified from a photo.
What to do
To control it in lawns, pull it with the whole taproot; a dense, healthy lawn crowds it out.
