The Laurens Henry Cohn, Sr. Memorial Plant Arboretum is a beautifully landscaped 16-acre tract of heavily wooded land used for the preservation and study of native plants and flora from other areas. It’s the perfect place to relax and unwind. The Arboretum features more than 300 species of native and adaptable trees and shrubs, a fruit orchard, butterfly garden and bamboo collection.


The property that became the Cohn Arboretum previously served as the family’s home. It was originally acquired by the Cohns from Maggie’s father in 1924 shortly after her marriage to Laurens.

Laurens Henry Cohn, Sr., a World War I veteran and former LSU tiger, was a devoted lover of nature and had a passion for cultivating both native and exotic plants. The land for the arboretum was donated to BREC in 1965 Maggie deBretton Cohn with the purpose of honoring her husband Laurens Henry Cohn Sr. after his death in 1965. The arboretum was converted into the sanctuary for plants and animals, and opened to the public in 1980. The original Cohn home still stands on the site as a museum.
