Wild Wednesday - Common fleabane
This wildflower shines brightly across the wetlands and meadows of West Sussex - the common fleabane, scientific name, Pulicaria dysenterica.
With its sunshine-yellow blooms and rich folklore, this plant is a star of late season biodiversity and a familiar sight in our local countryside.
In West Sussex, common fleabane can be found glowing in damp meadows, ditch edges and marshy patches, classic habitats throughout England and Wales. Its flower heads resemble miniature sunbursts, drawing the eye with golden-yellow daisy-like blooms.
Look closely and you'll see that what appears to be a single flower actually has several elements - a dense central dome of tiny tubular florets, ringed by delicate florets. This design, characteristic of the aster family, is shared with beloved plants like daisies, sunflowers and chamomile.
If you stop by a patch of fleabane on a sunny day, it's impossible to miss the buzz. In West Sussex's late summer, these flowers become miniature wildlife airports with hoverflies darting in, honeybees drifting between blooms, wasps and butterflies resting and feeding. The plant provides abundant nectar and pollen at a time when fewer flowers remain in bloom, making it a valuable resource for pollinators.
The Sussex Wildlife Trust notes how brilliantly active these plants are in our landscapes, from sunny field edges to wet grasslands. Their observations describe how fleabane continues bringing colour and ecological life long after many flowers have faded, supporting a rich mix of insects across our county.
Common fleabane carries a surprisingly rich and quirky history:
- the name “fleabane” comes from the belief that dried or burnt fleabane repelled fleas
- its scientific name, Pulicaria dysenterica, references its historic use treating dysentery
- old herbals even claimed that binding fleabane to the forehead could treat skin disorders
While these historic uses vary in reliability, modern ecological value is undeniable. Fleabane remains an important wildflower for pollinators and enriches wetland biodiversity wherever it grows.
Common fleabane typically flowers from July to September, making late summer its peak season. It thrives in moist soils, including marshes, ditch margins, damp meadows, and stream edges - habitats commonly found across West Sussex.
If you're walking near the Arun Valley wetlands, coastal grazing marshes, or damp woodland clearings, keep an eye out for its bright yellow blooms swaying above downy stems.
Why it matters
This humble wildflower offers:
- support for bees, hoverflies and butterflies when few other plants are blooming
- habitat value for wildlife-rich wetland ecosystems.
- a splash of colour as summer transitions into autumn.
In a changing climate and ever-fragmented habitats, resilient native species like Common fleabane help maintain healthy and connected landscapes - something we deeply value here in West Sussex.
