Irish Lady’s Tresses produces elegant, creamy-white flowers arranged in a spiral around the upper part of the stem, giving the plant a braided or twisted appearance—hence the name “Tresses.” Each small flower is tubular with a flared, three-lobed lip and a yellowish throat. Blooming from late July to early September, it is one of the last native orchids to flower in Britain and Ireland. The flowers are pollinated by bees, attracted by both visual cues and subtle fragrance.
Fruit:
After flowering, the plant forms narrow capsules that contain vast numbers of tiny, dust-like seeds. These are dispersed by wind and can travel great distances, but—as with all orchids—successful germination depends on the presence of compatible mycorrhizal fungi in the soil. The reproductive cycle is tightly bound to its wetland environment, and seedling establishment is rare without stable, undisturbed conditions.
Leaves:
The leaves of Spiranthes romanzoffiana are long, narrow, and grass-like, forming a basal rosette that often persists into the flowering period. They are bright green, slightly fleshy, and smooth-edged. A few smaller, alternate leaves may appear up the lower stem. The foliage is most easily seen earlier in the season before flowering begins and can be hard to spot among surrounding grasses and wetland vegetation.
Fragrance:
The flowers of Irish Lady’s Tresses are subtly fragrant, with a sweet, vanilla-like scent most noticeable in warm, humid weather. The fragrance helps attract pollinators such as bumblebees, which are drawn to the spiral arrangement of the blooms and guided by the flower’s pale colouring and scent. While not overpowering, the scent adds to the plant’s delicate charm and contributes to its pollination strategy.
Other Names:
Hooded Ladies' Tresses, Hooded Lady's Tresses, Pink Lady's Tresses.
