Giant Rhubarb, Gunnera

Gainera plant is also called Narrow Petal Frangipani or Narrow Petal Plumeria.
Narrow Petal Frangipani is a cultivated hybrid derived from a cross between Plumeria stenophylla and an unknown parent. The tree grows mostly up to around 1.5-2 m tall and is deciduous, therefore losing its leaves during long, dry periods.
