"Absolutely not," I said, "You're talking to a nurseryperson and we're the Original Plant One of Everything type of gardener. The thing is there is an element of truth there about planting more than one of something, and it's that weaving a color throughout the garden will make the effect more cohesive and will pull it all together. Now, do you have to plant 20 of the same thing to achieve that effect? No! Take me, for example, I like plants with burgundy foliage. Do I plant 50 of the same burgundy-leafed heuchera around the garden. Nope. But, I look for other plants with the same color in them: loropetalum, purple wood spurge, coleus, alternanthera, etc. in order to bring that color through the garden without having to plant the same thing. So, just think of it that way and you can have variety without ending up with a complete hodge-podge in your garden."
