Blue Water-speedwell - Veronica anagallis-aquatica

    Description

    A plant of medium height with erect, often stout stems, sometimes much branched. Leaves linear to linear lanceolate, all unstalked. It is very similar to the more frequent Pink Water-speedwell but the flowers are bluer.  The two species do hybridise, so care is needed with identification.

    ID guidance

    Check the capsule - V anagallis-aquatica = more or less round, not or shallowly notched at apex; V catenata = capsule wider than long and deeply notched at apex.  In fruit, V anagallis-aquatica has pedicels that are usually pointing up at more than right-angles; V catenata has pedicels at right-angles to stem

    Recording advice

    Unless identified by a recognised expert, a photo is required. If the photo doesn't show the key ID features then in the comments box describe the size and identifying characters you have observed.

    Habitat

    Found on fertile substrates by rivers, streams and ponds, in ditches and in flooded clay- and gravel-pits. It grows as a vegetative plant submerged in shallow water, or as a flowering emergent, or as a terrestrial plant in marshy habitats and disturbed ground at the water`s edge. 

    It is occasionally introduced around new drainage and SUDS ponds as a component of wildflower seed-mixes for aquatic plant margins
