Formal garden design is based firmly around structure, geometry and symmetry. These core principles can create real magic in any backyard, large or small, bringing harmony, balance and a calming sense of order to create a space that's easy and delightful to spend time in.
The best plants to complement a formal style of garden reflect that geometric style, with clean lines, defined shapes and architectural qualities that last all year round. Evergreen shrubs, clipped topiary and pleached trees are classic examples that garden designers and landscapers turn to time and again. Among those structural plants, elements of colour and vertical interest are also key, so perennials and flowering shrubs that offer long-lasting colour.
