|The Arboretum has developed several collections of plants that it features in beds throughout the gardens.
These collections include the Hardy Fern Collection; the Holly (llex) Collection; and the Arboretum's most notable collection of Azaleas, which is showcased primarily in the Jonsson Color Garden, but also prominently displayed throughout the grounds. Naud Burnett II, the landscape architect that completed the design and installation of the 6 1/2 acre color garden, used Azalea varieties to visually unify the garden. Today our collection contains about 2,800 specimens.
The Hardy Palm and Tropical Collection is the most recent addition to our collections and was donated by the First Men's Garden Club of Dallas with Tom & Nancy Wilten. This collection displays hardy palm species suitable to our climate and is located behind the Water Walls feature in the Lay Ornamental Garden.
