Woodruff – Galium odoratum

whorl woodruff

Leaves and Stem

Like goosegrass, it has ‘square stems’ (square in cross section), and the leaves are arranged in around it in whorls.   There are six to eight leaves in each whorl.  The leaves are dark green and are slightly shiny.
Individual leaves are about 4 cm long (when mature) and pointed with fine ‘prickles’ on the leaf margin (edge).  The prickles may also be seen on the central / main vein on the underside of the leaves (see image below).

The leaves are hairless as is the stem (except for some beneath each whorl).

When bruised or crushed, the leaves emit a scent like that of vanilla or fresh hay.

Flowers and Fruits

The flowers are small (about 3 to 4 mm across), arranged in clusters and white.  There are four petals (in a star-like configuration) to each flower, and four protruding (cream coloured) stamens.


When pollinated and fertilised, the fruits that form are bristly.
