I'm a mixture of styles. For my clients, it's easy to plan / install / maintain, because I can be objective about it.
For my yard, it's a constant jugging act to fit in whatever I brought home, and make my various plant collections look like gardens instead of a plant zoo. One of this, one of that...whatever catches my attention at the nursery. The idea of ever being "done" with my yard makes me shudder. Half the fun is moving plants around, trying new plants and different plant combinations, and seeing if I can grow plants in a large range of conditions. When I use a plant in a client design, I've already tried it in half a dozen places in my own yard. This experimenting really helps in design, because very often you have a long bed that is sunny on one end and shady at the other, especially where the house casts a dark shadow.
