Coleus
If you’re looking to add dark flowers and foliage to your beds and container gardens, a dark purple Coleus is a perfect contrast to bright pink and orange flowers.
Coleus can be added as an upright, rounded, or trailing plant depending on where you’d like to add in the dark color. It grows well in pots and planters, as well as in garden beds. To maintain the shape of your plant, pinch back every few weeks.
