Indian Rhubarb
Darmera peltata
  
About Indian Rhubarb (Darmera peltata) 11 Nurseries Carry This Plant Darmera peltata (Indian rhubarb or, ambiguously, "umbrella plant") is the only species within the genus Darmera in the family Saxifragaceae. It is a slowly-spreading rhizomatous perennial from mountain streamsides in woodland in the western United States (southwestern Oregon to northwestern California). 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 centimeter across each) borne on flower stems up to 2 meter long. The leaves are peltate, rounded, deeply lobed, coarsely-toothed, conspicuously veined and dark green, also on stems up to 2 meter 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. It is easy to grow in the cooler climates of its native range, but is not happy in hot southern areas.

D. peltata has gained the Royal Horticultural Society's Award of Garden Merit.
