 Comments: Cardinal flower is easy to identify from other lobelia due to its deep red color. Sometimes a rare pink or white variety will appear.  The lobelia flowers are actually upside down or inverted.  The three bottom lobes are actually the upper lobes and vice versa.  

Etymology: The name Lobelia comes from a 16th century botanist Mathias de Lobel. The epithet name, cardinalis, is derived from the robes worn by Catholic Cardinals.  

  

Landscape: Cardinal flower is one of the most attractive wildflowers in Indiana. Its deep red colors put a spotlight in your garden.  It does need moist soil. Hummingbirds are an important and primary pollinator for Cardinal flowers.
