Geum is a perennial herbaceous plant useful for planting at borders, providing colorful flowers over a long period in early summer. Geum species are used as food plants by larvae of some Lepidoptera species including Grizzled Skipper.
(Water Avens, Nodding Avens, Drooping Avens, Cure All and Water Flower) is an upright perennial. It is native to Europe, with the exception of Mediterranean areas, as well as some parts of Central Asia and North America. It is known as Purple Avens in North America. It grows in bogs and damp meadows, and bears nodding red flowers from May to September. The plant grows in slow-draining or wet soils and can tolerate mildly acidic to calcereous conditions in full sun or partial shade. Its habitats include stream sides, pond edges, damp deciduous woodlands and hay meadows. Geum rivale
is pollinated primarily by bees, less often by flies and beetles. Its seed are burr-like, and are distributed after being caught in the coats of rabbit and other small mammals, and by rhizomal growth.
Geum is an easy to grow and trouble-free plant, and can tolerate a wide range of conditions but it will not thrive in water-logged soil. It grows well in full sun, fertile and well-drained soil. Propagation is by seed in spring or autumn.
