Incorporating bird-friendly plants in your built-in indoor hummingbird and bird feeder garden is a fantastic idea. Choose plants that attract a variety of colorful bird species, such as sunflowers, coneflowers, and butterfly bushes. These plants provide food and shelter for birds, making your kitchen garden a haven for them. Not only will you enjoy the vibrant colors of the flowers, but you'll also have the pleasure of watching different bird species visit your garden throughout the year.
