The cartwheel is one of the most traditional herb garden designs and merely involves creating a circular garden bed, divided into segments like a pie. You can define the segments by installing weed barriers and creating gravel-filled paths between the segments. Plant different herbs in each section of the wheel, paying particular attention to the plant's requirements for sun or shade. The cartwheel-style herb garden can be any size to fit large or small backyards, in average, well-drained soil that receives at least six hours of direct sunshine. Landscaping a circular herb garden design around a small, central circle provides an effective appearance while creating segregated beds for a variety of different herbs.
The knot-style herb garden consists of two pairs of parallel pathways crossing each other in a square garden bed to create nine separate herb beds for your planting. You would traditionally plant low-growing herbs at the front of the beds and taller plants in the center. You can create your own design for an individual knot garden that enhances your garden landscape.
You can create an informal and interesting design on your patio or deck with a variety of different pots of herbs. This gives you the benefit of being able to access your herbs at any time and whatever the weather, while different sizes and colors of pots add to the overall visual effect of your casual herb garden.
Another idea for growing culinary herbs within your garden landscape is to add them into regular flower borders for a cottage garden effect. Rosemary (Rosmarinus officinalis), perennial in U.S. Agricultural Department plant hardiness zones 8 through 10, is a good example of a culinary herb that can be easily cultivated within the flower border. You could also establish small, rectangular borders close to your kitchen door in which to grow your favorite herbs. When space is at a premium, it is also possible to set up a range of pots and planters on a sunny windowsill indoors to grow your herbs.
