This week's Isles of Scilly Wildflower Of The Week was Broad-Leaved Willowherb - Epilobium Mountanum.
Broad-leaved Willowherb is not widespread on the islands. It is a common plant on the mainland. It has been found on St Mary's, St Agnes and Tresco. It likes cultivated fields and disturbed ground. I found a plant growing in a road drain.
Willowherbs, whether tall, medium or short are very similar with four pink notched petals, and upright habit, toothed lanceolate leaves and long thin pods that split to release seeds with long silky hairs. It is all about the detail as to which willowherb you have found. To be sure we have Broad-leaved willowherb the stems must be round, the stigma 4-lobed and the leaves are usually broader than other willowherbs.
The botanical name, Epilobium mountanum, means upon pod, as the flower seemed to be growing on the seedpod, and of mountains.
The 17th-century herbalist Culpepper thought all the willowherbs could be used to treat haemorrhaging. In Austria the leaves were used in traditional medicine, as a tea, to treat prostate, kidney and urinary problems.
The windborne seeds and the creeping stems of Broad-leaved willowherb make it difficult to get rid of in the garden.
