The Arboretum is bursting when bloom from spring through fall, but have you ever looked at the color and texture of the Arboretum in the winter? To most, the winter garden is dreary and lacking all color, but a closer look will prove otherwise. Really look at a tree’s bark. It is the tree’s outer protection layer. It also is a thing of beauty in and of itself. Each tree has its own distinctive silhouette and bark.
- The ginkgo (Ginkgo biloba) row by the pergola has the most identifiable bark accented spurs on its branches.
- The Kentucky Coffee Tree, our Heritage Tree, is another readily recognizable one by its dark gray, fissured scaly surface and narrow ridges. Its botanical name ‘Gymnocladus dioicus’ meaning ‘naked branch’ describes it thick twig-less branches. The winter buds are minute, but not its pods, which measure 6-10 inches with 6-9 dime-sized seed.
- The Sycamore (Plantanus occidentalis) has white bark cannot be missed even in the summer. Its lower trunk is splotchy shades of gray and tan, but the upper is smooth snowy-white that highly contrasts against the winter sky and its surrounding dark-barked neighbors. As stunning as it is, it is not a tree for small places as it can easily reach 150 feet.
- And, Northern Red Oak (Quercus rubra). The Kentucky big tree champion grows to the left of the Wallis House front drive. This species is found in most of Kentucky’s 120 counties. Its bark is noted its the shallow fissure and smooth ridges that sometimes having a striped appearance. Other oaks have a similar striping, but only the red oak stripes run the length of the trunk.
These are just a few of the wonderful winter trees in the Arboretum. Come visit on your own, or for a group tour of the Arboretum: call 859-987-6158 and leave a message. Wallis House is available to rent for special events and meetings.
