I saw conifers representing the Appalachian Plateau, dogwood and coffeetree for the Knobs and tall grasses for the Pennyrile Region.
The Bluegrass Region, where Lexington is located, is the most extensive, with bur and chinquapin oaks, several types of ash tree and outcroppings of shaggy limestone.
Ambling through the Arboretum warmed me up, wore me out and educated me, too. After just one visit I can tell it will be one of my regular hometown routes.
