Tubular water-dropwort Oenanthe fistulosa is a perennial wildflower which is mainly found in boggy areas such as marshes, pond edges and fens. It doesn’t spread particularly easily to new wetland habitats, tending to prefer permanently wet soil which is rich in lime. Be aware that it is a poisonous plant for both humans and animals. It is a priority species under the UK BAP. 

How to identify

Tubular water-dropwort can grow to 80cm, having hollow stems with green-grey pinnate leaves. It has pompom-like umbels of white flowers which emerge from July onwards.

Where to find it

This plant is much less common than it used to be and is therefore classified as “vulnerable”. It is, however, still in fairly good numbers in the south of England including the Upper River Ray, with smaller populations in Scotland and Wales.


When to find it

  • July
  • August
  • September
