(Northeastern Oklahoma)


The following list is only the starting point for trees that can be grown in this portion of the state. Many new species and varieties are introduced into the local nursery trade each year. Only time will tell how successful they will prove to be. Some trees appear to be very successful, become popular, and are overplanted. This can lead to an increase in insect and disease problems. Do your research carefully because your trees are a long term commitment.
