So unity in order are referring to the form composition of your garden, while freedom deals with time and movement, how people are moving through the garden. So when we're looking at landscapes, we see it in a period of time and a variety of use. And these are going to be seen in a sequence. So mentally, we are starting to create pattern. So what we can do as designers, we create freedom to use in our designs. And we can do this by using four different but visually related patterns, repetition, gradation, inversion, and alternation.

So let's have a look at some examples of these. So let's start with repetition, which is just a principle of taking elements or group of elements and repeat them to form on our base sequence. And this can be done with paving or stepping stones is very heavily done. Which plants as well. So let's see how this can be done and how you can use the rhythm to move you down through the garden. Here is a combination of planting design and the paving selection.

And here the white flower of azaleas are seeded into the distance as they get further from us, and they tend to close a little bit further into the pathway. You can see a bit of tension and a perspective and also the dynamic pattern of the break pathway creates a visual stimulation and tends to move you down into the garden. The repetition in planting or paving materials can be used to create a movement in a garden. It's pretty easy to envision and implement in a design whether you are using it in a planting scheme, or different paving materials and repeating patterns or the same materials throughout the garden. Now we're going to look and talk about the next visual pattern which is called arctan. alternation is taken the same repetitive pattern.

But now we're going to take this same repeating pattern, and we're going to change one of the elements within it. So now we're having an alternating visual pattern, or an alternating sequence within the composition. In this example, are taken announcer nation in fencing. In this picture, we have a stone wall with some iron fence panels. So you can see repetition here, but alternated. In the second picture, it's an example of alternation with plant form.

So we have a pyramid trees, and then alternated with some kind of hedging material in between. So again, creating a sequential representative pattern and alternate. Finally, we can do the same thing with colors and if you are designing a perennial border, then it's nice to be able to bring in a representative fashion to it. And you can do this with a trial of colors. For example, you Low red and blue and then repeating it, the species don't necessarily have to be the same but the colors create a sequential pattern, the written that makes your right skip along a perennial border. And of course in the real perennial border, you would have different colors in the background, maybe some deep greens to set it off.

But these colors are what are going to lead the eye down the border. And that's what I mean by using alternation to create more interest in your garden design. So now let's take a look at what invasions would entails. This is done mostly in painting materials or colors. So in this example of invasion, we have a stone walkway coming into the house and it has a brick pattern around the edge and then it sets it off with some hedging materials. As you get to the porch what inversion is stating is that now materials used here swapped so we have the stone edging and the break us As a main surface, so these elements have been inverted changed out.

So this is just a simple explanation of what inversion is and how it can be used and it can be very effective in your designs. Let's quickly look at graduation now. Here is an example of using plant materials. It's a very typical planting scheme where you have the lover planting at the front and it gradually gets taller and taller towards the property line to create this gradual climb or gradation of height. This can also be done in an architectural way, let's say with the fence panels. Or you can also add a little automation to it by changing the panels which are horizontal or 45 degrees.

So a graduation in the profile view. You can also do a very nice gradiation on a ground plan, for example with a pathway when you start off with a by the path As you are coming closer to focal points, you narrow the pathway more and more. So there you have four ways how to create rhythm in your design, repetition, alternation, inversion and gradation. And you can combine them in between them. And that's what's gonna make your designs more interesting. And we'll get people want to get out there and explore.

So again, practice with this research on it, and start using them. We're gonna wrap this lesson up next. So I'll see you there.
