FG: How does manipulating the shapes of plants help to define a garden?
RG: You can take plants and clip them into geometric forms to create the effect of a pattern or a shape, then repeat that shape. You can create a boxwood ball or you can make flat-top squares out of boxwoods. If you like whimsical topiaries, you can create a poodle, or a rabbit, or a chicken on a stick. Do whatever you want to do, but it’s all clipping. That’s the part of gardening that people misunderstand: Manipulation is what gives us structure. You shape, you clip, you peg, you bend, whatever. I hear people say, “I don’t like that; that’s horrible.” Well, you know what you get when you take the formal structure out of your body? You get a jellyfish, and who wants to be a jellyfish?
FG: Is it difficult to bring many different elements into a garden?
RG: It’s all about taking as much as you can and getting it in one place, but keeping it simple and making it beautiful. You can embrace all those nuances of the past—pattern, manipulating plants, stonework, temples, follies, ruins, vistas, views, nature, and water. I think a complete garden is composed of all these elements, and you can have that on a terrace. You can grow plants in pots, you can have patterned stonework, you can have a clipped hedge, you can cut holes in the hedge, you can create a wall for enclosure, then cut a hole in it to have a view. The key is to understand the complexity of simplicity.
FG: How do you do that?
RG: By saying “No, no, no, no, no, no, no. You can’t have that, you can’t have that, but this you can have.” You have to make hard decisions. Sit down and figure out what you want. Train yourself to really see things, to feel, to become intimate with the whole experience of something. In other words, I look at a flowering plant and I think, “I want one of those,” then I look at it more deeply. I find out how it grows, how big it gets, whether I can shape it or whatever, and then I think about whether I can truly make a place for it in my garden.
FG: How would you encourage people to expand their sense of possibility?
RG: I think traveling to different places is essential. Go look at botanical gardens, arboretums, private gardens, public gardens. And when you’re there, look, look, look, and then go back and look again. Try to figure out what you want that you would be willing to implement and maintain. Try to see what really stirs the passion that is essential to making and tending a garden.
