A little weed, common in gardens and waste places, with smooth, four-sided, stems, branching and half trailing on the ground, smooth, toothless, bright green leaves and charming little flowers, a quarter of an inch or more across, with a five-lobed calyx and wheel-shaped, five-lobed corolla, usually bright orange-red and darker in the center, rarely white; the stamens five, with hairy filaments; the capsule smooth and roundish, containing many minute seeds. The flowers and leaves are usually in pairs, the seed-vessels on the tips of slender stems, curving around and toward each other, as if the plant were stretching out its little hands, and opening its little blossoms only in bright weather and closing them at night. The Greek name means "amusing." The plant was used medicinally by the ancients.
There are three kinds of Trientalis, much alike, perennials, with tuberous roots. The Latin name means "one third of a foot," the height of these plants.
