Distinguishing Characteristics
This is a sprawling perennial herb to 15 cm in height with numerous stems branching from the base, sometimes it forms dense clumps.

Stems spread horizontally with the ends growing upwards or weakly erect, they are slender, branched, ribbed and sparsely-hairy to smooth.

Leaves are deep green above and grey/green below. Lower leaves are 3-lobed or 3-5-toothed at apex; upper leaves are linear-lanced or elliptic, entire to toothed or shallowly lobed with a short leafy stalk. Leaves are in clusters arranged alternately along the stem.

A pleasant smell is given when crushed.

Only a few flowerheads can be found on slender, almost hairless flower stalks. Ray florets (petals) grow in several rows and are often pale mauve, turning white and becoming pink with age. Disc florets (tiny yellow flowers in the centre of the "flower") are numerous with yellow petals.

Fruit is an achene which is pale brown, oblong and sparsely hairy. The pappus (the appendage on the seed) consists of fine whitish hairs. The seed is very fine and spreads easily assisted by the wind.

This plant is easy to remove.
