Grows in gatherings in damp places near water, rather than in water, for despite its name it is not aquatic. |

The brownish-purple looking flowers droop, stalks bent in inverse umbrella-handle fashion. |

A set of trifoliate leaves grows half-way up the stalk, reminiscent of Fringe Cups. |

A single clump. |

The buff-coloured petals of the flower are always mostly hidden by the five purplish brown sepals. |

The flowers always droop downwards, never displayed upwards. |

Unlike the hybrid between Water Avens and Wood Avens (which is called Hybrid Geum), this has pink petals that are flattish and shaped as of a spatula with rounded notches in the middle of the ends. |

The flower profile has a distinct pentagonal appearance. |

A hoard of anthers crowd around the central brush of styles. |

Later the seeds start to emerge from the centre like feathery hairs from the mouth of a monster. |

And the flower head at last starts to present itself upward looking. |

The feathery seeds have a distinct twist in the tail: they can travel either by air using the feathers or by the kinked 'hook' getting caught in the fur of passing animals. The hairs are similar to the hairs of those attached to the seeds of Virgin's-Bower. |

Lower leaves are an irregularly toothed trefoil shape. |
DOUBLE-FLOWERED MUTATIONS |
These double-flowered forms were all found growing amongst many perfectly normal Water Avens. There are red, pink and the usual Water-Aven pale buff colours. As is readily apparent these double-flowered forms have many more petals than just a doubling. Perhaps a better description would be triple- or quadruple-flowered. Un-like most double flowered flowers where access to the inside is physically restricted by the proliferation of petals, access to the innards in these examples seems easy.

These are not hybrids, but naturally-occurring mutations, which are fairly common in Water Avens. |

The petals on this specimen have the normal buff colouring of Water Avens. Un-like most double flowered flowers where access to the inside is physically restricted by the proliferation of petals, access is easily afforded by visiting insects (but whether the plant is sterile, as is usual in double-flowered forms, is not known). |

'Hooked' kinks are forming in the centre, but are there seeds on the other end?). There are far fewer anthers in this specimen, and it looks likely that many of the anthers have mutated into petals. |

This specimen looks different to the other mutations: is that an (albeit abnormal) tiered flower emerging (on a flattened fasciated stalk) from the centre? |
Not to be semantically confused with : Gean aka Wild Cherry (Prunus avium), a tree which happens to belong to the same family, Rose (Rosaceae) Hybridizes with : Wood Avens to produce Hybrid Geum. Fully fertile hybrid swarms proliferate where the parents meet, with the hybrids exhibiting a full spectrum of intermediate forms between the two parents covering every aspect. Distinguishing Feature : From afar the way the leaves are shaped and are widely spaced on one side up the stem resembles that of Fringe Cups Water Avens is taking advantage of two methods of seed dispersal; by both hooks which latch on to animal fur (or human clothing) and by wind dispersal by means of short feathers on the hooks. Because the hairs are relatively short and the hook relatively heavy, a stronger wind would be necessary to carry the seed, when there are fewer animals about (they are sheltering from the wind). There's nothing like hedging your bets.
