Filipendula ulmaria Meadowsweet CCC DD N
This is a common plant of wet places, damp verges, edges of forest rides and soggy soil generally. You can see plenty of this in drainage ditches by the roadside in summer. The systematic name for this plant was once Spiraea ulmaria and it yielded a substance known as Salicin from which Acetylsalicylic acid was first derived. This new substance was called Aspirin after the "Spiraea" genus name of Meadowsweet.
Meadowsweet is found throughout the British Isles and Ireland.
