17th July 2013, White Hill, Marsden, West Pennines. | Photo: © RWD |
2012 saw the wettest rainiest year since records began. The year after, 2013, had the best summer for over 10 years. These two conditions compounded together to a produce a profusion of Cottongrass covering the peatland moors painting them white like a sprinkling of snow for tens of miles around. Although Blackstone Edge on horizon, this is White Hill. It is now patently obvious why it has this name, not so obvious at all in previous years. |

Not to be semantically confused with : Cotton Thistle (Onopordum acanthium) [a plant with similar name belonging to a differing family]
Can be mistaken for : other
Some similarities to : Hare's-Tail CottonGrass (Eriophorum vaginatum) but that has only one flower-spike, whereas Common Cottongrass has several (between 3 and 7). Uniquely identifiable characteristics Distinguishing Feature : When in fruit has multiple flower spikes with hairy pappuses and growing on acidic wet upland peat areas.
No relation to : Cottonweed (Achillea maritima) [a plant with similar name belonging to the Daisy & Dandelion Family (Asteraceae)] nor to Although superficially similar to some grasses (Poaceae, Cottongrasses are in the Sedge Family (Cyperaceae). The flower spikes first have cream coloured anthers protruding from during April to May after which the hairy fruiting head develops in June to last two or three months before the seeds on the hairs are blown to pastures new.
