I actually live in South Central Kansas, but I called Heartland Nursery to find out if tulip poplar trees grow well in the Kansas City area. (I won't explain why I was trying to discover this. It is a long story.) Anyway the young lady who answered the phone was very polite and professional. I even put her on hold for a couple of minutes, and she was still on hold and still very pleasant when I got back on the phone with her. I have never purchased plants from this nursery, but if the product is as good as the customer service I received over the phone, then the plants must be excellent.
I love this place because of the variety of flowers, shrubs, trees that they provide. That is why I rated this so high, HOWEVER, if this was based on customer services and prices alone they would probably get closer to a 1.5. Usually the outdoor workers (dealing with the shrubs/trees) are very helpful but the ones inside lack personality and customer service skills. It is just so hard to not love this place when you see all the flowers, it helps mask the lack of customer service.
They have such a variety of plants that you feel like a kid in a candy store. I have never had bad customer service there. I have always been able to ask anyone on the floor for help and they all are very knowledgeable about the flowers and plants they sell there, or know who to ask.
