Designing Landscapes That Evolve Over Time

After completion, a landscape continues to grow and change. In contrast to buildings, which remain static and unchanging for decades, plants increase in size, hardscapes patina and weather, and seasonal changes alter the character of every aspect of a landscape. This evolution is one of the unique challenges and rewards of designing landscapes. Rather than aiming to finalize every last detail at the end of a project, landscape architects work to envision how the space will mature in the years to come and encourage it to develop into a more complex and dynamic environment over time.

Growth is a critical aspect of designing for the future. Trees grow wider, shrubs get fuller, and groundcovers spread to fill in gaps between plants. While the resulting landscape may appear unfinished in the first year after planting, it will blossom into a full, verdant oasis as the plants mature. To account for the changing size of plants, landscape architects will often leave space between plants in the planting plan, which allows plants to grow and fill in without becoming overcrowded.

Similarly, allowing enough time for plants to mature results in a more relaxed composition than trying to force a certain aesthetic immediately. Just like plants, hardscapes age and change over time. The appearance of pavers will darken and change as they weather, wood develops a patina when exposed to sunlight and rain, and paths develop character as they are used. Aging is a natural aspect of the materials used in a landscape and should be embraced as part of the design.

When properly selected and maintained, these changes will enhance the natural quality of the space and help it feel more at home in its surroundings. Ecological balance also plays a role in how a landscape changes over time. A healthy ecosystem will be able to adjust to fluctuating rain patterns, varying degrees of sunlight, and fluctuating temperature changes from season to season. Choosing plants that are adapted to a region will minimize the impact of these fluctuations and require less maintenance over time. With proper care and management, the ecosystem will be more resilient as time passes and will require less meddling to keep it healthy and looking good.

This balance also helps the ecosystem feel more natural and will support the visual harmony of a design over time. In general, the long-term maintenance and evolution of a landscape requires vision and restraint. Rather than imposing a specific will on a space, a designer must allow it to develop and mature over time, embracing the natural evolution of the space. As the seasons pass, the landscape will develop its own character, with the original design evolving into a unique marriage of intention and circumstance.
