Epilobium brunnescens New Zealand Willowherb I
This plant was first noticed as an introduction around the turn of the century since which time it has spread to many hilly places in the British Isles. It is one of the easiest of the Willowherbs to identify because it looks so different from the others. The flowers often open only partly to a cup shape and need strong sunshine to open flat looking much less pink when they do. The leaves are very similar to Anagallis tenella (Bog Pimpernel): flat to the ground and with round pinnate leaflets. The long fruits from this prostrate plant are typical of willowherbs.
E. brunnescens is found amongst all the hills of northern England, Scotland, Wales, Cornwall, much of Ireland excluding the central flat parts but is not found much in the more basic lowland soils of central and southern England.
