The Sword-leaved Helleborine grows to about 40 cm in height and is distinguished from Cephalanthera damasonium by the shape of its leaves, which are long and narrow. Both the Latin namelongifolia which means long-leaved and the English common name 'sword-leaved' refer to the distinctive shape of the leaves.
The flowers are white, and there is a distinctive yellow patch on their lips.
Although generally associated (in the UK, that is) with the chalk-rich habitats of southern England, the Sword-leaved Helleborine also occurs in western Scotland, in a few sites in Ireland and on the western fringes of Mid and North Wales. This species is in steep decline both in the UK and throughout mainland Europe, where it is widespread but nowhere very common.
Although mainly associated with woodlands in the UK and France, we have seen Sword-leaved Helleborine in a number of other habitats including on roadside verges. In the Algarve region of Portugal Cephalanthera longifolia can be found sheltering in the lee of dry stone walls and at the base of slopes where moisture tends to collect, but always where trees are never far away.
In the UK and France Cephalanthera longifolia flowers in June, but in southern Europe it comes into flower much earlier, often in February and March.
The specimens shown on this page were found in the Algarve during late February.
