Coleus are one of the most popular foliage plants available. They have some of the most stunningly colored foliage—in combinations of green, yellow, pink, red, maroon, etc. Coleus also have a wide variety of leaf sizes and overall shapes. This means that no matter what area you are looking to put coleus, you can find one that will be perfect. These plants are great for adding color in the garden (or home), especially in those dark, drab-looking corners.
