In Oklahoma, the most common tree species are the eastern redcedar and the blackjack oak. These two trees dominate the landscape in many parts of the state, particularly in the Cross Timbers region. As a gardening and landscaping expert, I have encountered these trees numerous times and can provide you with a detailed understanding of their characteristics and prevalence in Oklahoma.
1. Eastern Redcedar (Juniperus virginiana):
The eastern redcedar is a coniferous tree that is native to Oklahoma and widely distributed throughout the state. It is known for its dense, evergreen foliage and its ability to adapt to various soil types and growing conditions. The tree has a pyramidal shape when young, but it becomes more irregular and spreading with age.
– Appearance: The eastern redcedar has scale-like, dark green leaves that give off a distinct cedar-like aroma when crushed. The tree produces small, bluish-purple berries that are a food source for birds and wildlife.
– Adaptability: This tree is highly adaptable and can tolerate a wide range of soil conditions, including clay, sandy, and rocky soils. It can also withstand drought, making it well-suited for the often dry climate of Oklahoma.
– Role in the Landscape: Eastern redcedar trees have both ecological and landscaping value. They provide habitat and food for wildlife, including birds and small mammals. In landscaping, they can be used as windbreaks or privacy screens due to their dense foliage.
2. Blackjack Oak (Quercus marilandica):
The blackjack oak is another common tree species in Oklahoma, particularly in the Cross Timbers region. It is a deciduous tree that can withstand harsh conditions and is often found growing in dry, rocky, or sandy soils.
– Appearance: The blackjack oak has dark, deeply lobed leaves that are glossy on the upper surface and pale underneath. The tree gets its name from the resemblance of its leaves to the playing card “blackjack” or “twenty-one.”
– Adaptability: This tree is well-adapted to Oklahoma’s climate, as it can tolerate both drought and extreme temperatures. It is often found growing in areas with poor soil fertility and rocky terrain.
– Role in the Landscape: Blackjack oaks provide important habitat and food for wildlife, including deer and squirrels. In landscaping, they can be used to add a touch of natural beauty to dry or rocky areas. However, their slow growth rate and limited ornamental value make them less commonly used in urban landscapes.
While the eastern redcedar and blackjack oak are the most common tree species in Oklahoma, it is important to note that the state’s diverse climate and geography support a wide variety of other trees as well. Some additional tree species that are found in Oklahoma include the post oak, black hickory, sugarberry, and American sycamore.
The eastern redcedar and blackjack oak are the most prevalent tree species in Oklahoma. Their adaptability to Oklahoma’s climate and ability to thrive in various soil conditions make them well-suited for the state’s landscape. Whether you encounter these trees in the wild or incorporate them into your landscaping, they contribute to the natural beauty and ecological balance of Oklahoma’s environment.
