Epilobium coloratum Biehler
Purpleleaf Willowherb, Cinnamon Willow-herb
Cinnamon willow-herb, a North American native, is a member of the evening primrose family.
Identification: This species is quite variable. They have a vaguely disorganized look about them. Plants are 12-36" (30-91 cm) tall, erect, sometimes branching. Stems may be square or round. Leaves may be opposite or alternate. They attach directly to the leaf (“sessile”) or by a short stem, called the petiole. Leaves are toothed, narrow (“lanceolate”), up to 4" (10 cm) × ½" (1.3 cm). Flowers are ¼" (8.5 mm) around, with four white or pale pink petals, each petal with two lobes. The flowers are in racemes—loose clusters—and they appear from July to August. Each flower tops a “stem” about 2" (6 cm) long that develops into a skinny fruit, like a straight bean, about ¹/₃₂" (1.3 mm) around.
