半圆花坛设计

Quick answer：

A semi-circular flower bed design refers to the arrangement of plants or decorative elements in a semi-circular shape. This design can be found in gardens, parks, or public spaces, and is often used to create a focal point or to define an area. It allows for symmetry while also incorporating a gentle curve, which can be visually pleasing and less rigid than a full circle. The design considerations include plant selection, spacing, and the overall aesthetic balance.
