Rodney Barton's Hexagona Page
Rodney Barton's Hexagona Page previously was part of his North American Native Iris site, which is no longer active. Rodney generously permitted a move of the Louisiana iris species pages to the Zydeco species section.
Rodney lives and grows irises in Hickory Creek, TX, near Dallas.
