Not only was the hard-to-find honeysuckle plant I wanted beautifully healthy, but Chris made the extra effort to choose the healthiest plant of those available AND gently disentangle the vines from one another, give me a cart-ride back to my car and carefully load my prize find into my car. I will definitely look here for future plants. Many thanks!
Arrived on time. Did a clean and complete installation of our new tree. They also were able to answer a few questions as well. Very satisfied with the experience.
