Like many people, you may not have planned your garden to accommodate the fading color palette that often happens in the last summer. There are several plants you can plant to fill your landscape with color through early fall. If you missed planting them in the late spring then you might be able to find them in your garden center now. If you do, then strategically place them where you need to brighten up things and bring the color back to your landscape.
If you missed the late summer color planting in the spring or can't find them in your favorite garden center in August, then there's always next spring!
