I saw the small group in the distance. There were three of them; one was clearly a designer of some sort, while the other two were homeowners, listening attentively.
In our business, we see this scene every day. A landscape designer, often with a rolled-up blueprint under one arm, walking from plant to plant, motioning with their arms and talking with their clients.
We usually leave them pretty much to themselves, other than perhaps to help them find a plant or two that they wish to see. The clients already have a knowledgeable person guiding them in their needs, there's not much more that we can offer.
Nonetheless, wanting to be helpful, I stopped by to say hello and make sure that everything was going well with the trio.
I knew there were problems from the start, after I overheard the first sentence from the designer, "Let's find a short plant with grey leaves to put in front of these."
