Like succulents, herbs are among the easiest plants to grow in a container. Of course, you can also plant them in the ground. Most herbs have similar growing requirements as many succulent varieties, which is essential for companion planting. That said, your top choices are salvia, yarrow, rosemary, and lavender. Adding plants in your white succulent setup can help add color and texture and give your collection a savory scent and fragrance. Conversely, the succulent will make the herbs look more luscious and fuller.
