Before creating this panel for The Nature Conservancy in New Hampshire, I had no idea that giant rhododendrons where native to North America.  They are so big and showy, I assumed they were some exotic flower, but no, they are found throughout the Appalachian Mountain range.  New Hampshire is about as far north as they grow in the wild.   Makes me like the one planted outside my window even more.
