An isosceles trapezoid garden design typically involves creating a garden space with a trapezoidal shape where the non-parallel sides are of equal length. This design can be visually appealing and practical for maximizing space. Key considerations include selecting appropriate plants, ensuring proper drainage, and planning for walkways or seating areas. Isosceles trapezoids are geometric shapes with one pair of parallel sides and two equal non-parallel sides, which can be used to create aesthetically pleasing garden layouts.
