American Willowherb - Epilobium ciliatum
Medium to tall, often reddish plant, without stolons, stems erect with four raised lines. Produces leafy rosettes at the base during autumn. Leaves mostly opposite, oblong lanceolate, toothed. Flowers purplish pink, 8 to 9 mm, erect in bud, the petals deeply notched. Stigma club shaped. Many glandular hairs on the supper stem, sepals and parts of the fruiting structure
One of four similar species; E obscurum, E tetragonum and E roseum also have club-shaped stigma. E tetragonum has no glandular hairs and perennates with loose leaf-rosettes. E obscurum has few glandular hairs and perennates with leafy stolons. E roseum is very similar to E ciliatum but has longer petioles. Hybrids also occur.
