Ordered online and came the next day. Exactly what I was looking for. Tree was in great shape.
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!
