Transforming an urban backyard into a verdant escape from the outside world is a dream for many city - dwellers. With the right plant ideas and space - expanding tricks, this dream can become a reality. In garden design, various garden styles can be adopted to create a unique and relaxing environment.

One of the most popular garden styles for urban backyards is the Japanese Zen garden. This style emphasizes simplicity, harmony, and tranquility. To start with, you can use gravel or sand to represent water. Rake it into smooth patterns to give a sense of fluidity. Place a few carefully selected rocks, which symbolize mountains, strategically around the gravel area. These rocks should have interesting shapes and textures to add visual appeal.

When it comes to plants, Japanese maples are a great choice. Their delicate leaves change color throughout the seasons, providing a beautiful display. Bamboo is another classic plant for a Zen garden. Its tall, slender stalks sway gently in the breeze, creating a peaceful sound. You can also add some moss to cover the ground around the rocks and plants. Moss gives a soft, natural look and thrives in shady, moist areas often found in urban backyards.

Another style to consider is the Mediterranean garden. This style is known for its use of drought - tolerant plants and warm, earthy colors. Olive trees are a signature plant of the Mediterranean region. They have silvery - green leaves and can add a touch of elegance to your backyard. Rosemary, thyme, and lavender are not only fragrant herbs but also beautiful additions to the garden. Their purple, blue, and white flowers create a colorful contrast against the green foliage.

To expand the space in your urban backyard, vertical gardening is a fantastic technique. You can install trellises on the walls or fences and grow climbing plants such as clematis or ivy. These plants will cover the vertical surfaces, adding a sense of depth and making the area look larger. Hanging baskets are also a great way to utilize vertical space. Fill them with colorful annuals like petunias or geraniums to add a pop of color at different heights.

Grouping plants together can also create an illusion of a larger space. Instead of scattering individual plants randomly, cluster them in groups of odd numbers. This creates a more natural and cohesive look. For example, group three different types of shrubs together or plant a cluster of five perennials in a corner.

Using mirrors is a clever space - expanding trick. Hang a large mirror on a wall or fence. The mirror will reflect the garden, making it appear more spacious. You can also place a small mirror on a pedestal or in a decorative frame in the middle of the garden to add an element of surprise.

Lighting is another important aspect of garden design. In an urban backyard, proper lighting can extend the usability of the space into the evening. Solar - powered lights are a cost - effective and environmentally friendly option. Place them along the pathways, around the plants, or on the walls. String lights can also create a warm and inviting atmosphere. Hang them from the trees or across the patio.

Water features can add a sense of tranquility and make the garden more appealing. A small fountain or a pond can be a focal point. The sound of running water can mask the noise from the outside world and create a peaceful ambiance. If space is limited, you can opt for a tabletop fountain or a wall - mounted water feature.

In conclusion, with the right combination of plant choices, garden styles, and space - expanding tricks, an urban backyard can be transformed into a verdant escape. Whether you prefer the serenity of a Japanese Zen garden or the warmth of a Mediterranean garden, there are endless possibilities to create your own little piece of paradise in the heart of the city.
