Creating a bread garden in outdoor plant boxes is a delightful way to grow fresh ingredients for homemade bread. The best plants for this purpose include herbs like rosemary, thyme, and basil, which add aromatic flavors to bread. Edible flowers such as lavender and calendula can also enhance both taste and presentation. For a hearty loaf, consider growing garlic chives or onions. These plants thrive in containers, making them ideal for small spaces. With proper care, your outdoor plant boxes can yield a bountiful harvest for delicious, home-baked bread.
