About
Dichorisandra thyrsiflora or blue ginger is a species of tropical flowering plant which resembles ginger in growth and habit, but is actually related to the spiderworts (the genus Tradescantia). The plant is native to the tropical woodlands of North, Central and South America, especially in Atlantic Forest vegetation in Brazil. Of the family Commelinaceae, it is cultivated for its handsome spotted stems and large shiny foliage which is held horizontally, surmounted by striking blue flowers.
It was first described by the naturalist Johann Christian Mikan in 1823.
