Small-flowered catchfly description

GenusSilene (1)

The small-flowered catchfly is covered in soft hairs and has small narrow leaves and pinkish flowers that are arranged in loose groups called inflorescences and tend to point in the same direction (2). The common name refers to the fact that the plant is sticky, so much so that small flies can become fastened to the leaves or stem (2).

Height: up to 45 cm (2)

Small-flowered catchfly biology

Small-flowered catchfly is an annual plant; germination typically occurs in autumn, but occasionally in spring and so the plant can be present in both spring and winter crops (3). The species is sensitive to cold winters however, and seedlings are unable to survive in temperatures lower than 10°C (3).


Small-flowered catchfly range

This plant was once a common feature throughout the UK and the range extended as far north as Scotland. Following a severe decline the species now occurs mainly in the south and west of England and Wales (3). Elsewhere it occurs in central and southern Europe, but has largely become extinct in northern Europe (3).

You can view distribution information for this species at the National Biodiversity Network Gateway.

Small-flowered catchfly habitat

Inhabits cultivated and disturbed ground, typically arable fields on acidic sandy or gravelly soils, wasteland, and old walls. It is also found in open coastal grassland, and sand dunes in the Channel Islands (4).


Small-flowered catchfly status

Classified as Nationally Scarce in Great Britain (3).


Small-flowered catchfly threats

Like many arable ‘weed’ species, the decline of this plant is the result of widespread changes in agricultural practices, including the use of chemical fertilisers and herbicides, the loss of field-margins, earlier harvesting which denies the plants an opportunity to produce seeds, and the introduction of intensively competitive crops (3). At coastal sites, a further threat can arise from the pressures of tourism and other recreational pursuits (3).


Small-flowered catchfly conservation

This plant is a UK Biodiversity Action Plan priority species, and as such, a Species Action Plan has been produced to guide the conservation of the species. Plantlife, the wild plant conservation charity is the lead partner for this species (5). The Species Action Plan aims to maintain the current range of small-flowered catchfly, and aid the return of the species to at least eight former sites before the year 2003 (6). Furthermore, it has been proposed that an ex-situ population be established (3).

The UK Biodiversity Action Plan for this species is available at UK BAP.
