Sweetness of woodruff lingers down the ages

Benthall Edge, Shropshire This plant has had a symbolic, medicinal and folkloric importance for centuries

The margins of woodland paths are full of woodruff, white on green, and sheltered under trees is the ghost of its scent. Galium odoratum is the sweet woodruff, an erect perennial of limestone woods, 15cm-30cm high with square stems through whorls of up to nine leaves - the ruffs - ending in tight umbels of cross-shaped, bright white flowers that have a vanilla scent.

Woodruff grows in dense rugs in the shady woods of Benthall Edge at the northern limit of Wenlock Edge before it plunges into the River Severn of the Ironbridge Gorge behind Buildwas power station, whose abandoned funnel looms above the tree tops.
