|Darmera peltata flowers|
Darmera peltata (Indian rhubarb or umbrella plant) is a flowering plant, the only species within the genus Darmera in the family Saxifragaceae. It is a slowly spreading rhizomatous perennial native to mountain streamsides in woodland in the western United States (southwestern Oregon to northwestern California), growing to 2 m (6 ft 7 in) tall by 1 m (3 ft 3 in) wide. The name Darmera comes after Karl Darmer, a Berlin horticulturist from 19th century.
In late spring the flowers emerge before the leaves, with rounded cymes of numerous five-petalled white to bright pink flowers (measuring up to 1.5 cm across each) borne on flower stems up to 2m long. The leaves are peltate, rounded, deeply lobed, coarsely toothed, conspicuously veined and dark green, also on stems up to 2m in height. The leaves turn red in autumn.
In gardens, Darmera peltata flourishes in pond margins and bog gardens, where it forms an imposing umbrella-like clump. It is suited to smaller gardens where there is no room for Gunnera manicata or Gunnera tinctoria, unrelated plants that are somewhat similar in appearance, but much larger.
