Marsh-orchid, Early - ssp coccinea, Marsh-orchid, Early - var pulchella,

This delicate, slender wildflower grows in our fens and marshes and is not very commonly found, confining itself to a handful of counties only. In May and June it shows well-spaced pinkish-purple flowers on open spikes, each flower having well-marked, three-lobed lips, the middle lobe being longer than those to either side. The spikes of flowers tend to be somewhat one-sided. This wildflower grows to about 30 cm, bearing 2–4 linear-lanceolate basal leaves which can be either spotted or unspotted. A perennial, native plant, it belongs to the Orchidaceae family.

My first record of this plant was in June 2010 in Pollardstown Fen, County Kildare, on a trip to the Fen in the company of Jackie O'Connell. I also photographed it at that time. Brendan Sayers kindly confirmed my identification.

To learn more about our Irish orchids, I would heartily recommend a really superb book on the subject which is published by the Collins Press and entitled 'Ireland's Wild Orchids - a field guide'. 

Each of our native orchids is beautifully illustrated by the gifted botanical artist, Susan Sex and is an exquisite representation of an amazing plant; Susan's illustrations are complemented by carefully-chosen words from our National Botanic Gardens orchid specialist, Brendan Sayers. Susan's illustrations of key features of our native orchids are extremely useful when trying to identify a species and Brendan's descriptions help to broaden one's understanding of this complex and intriguing subject, and lead one nearer to making a possible identification. He also contributes information on the conservation of these magnificent little plants and gives details of where they might be found.
