As you design with a layered approach, it helps to have a sense of what your options are. Here are some examples of the types of plants that can create each layer.

Planting plan details

1. Design layer: Structural plants

These plants are the bones of the design, ensuring year-round presence.

2. Design layer: Seasonal theme plants

Using a wide variety of plants with peaks at different times of the year ensures continued waves of interest.

3. Functional layer: Ground cover and filler plants

This layer functions as a living mulch—one you don’t have to replenish yearly.
