If you're looking for a beautiful, low-maintenance addition to your garden, dianthus is an excellent choice. These hardy, perennial plants are known for their bright, fragrant flowers and their ability to thrive in a variety of growing conditions. But did you know that dianthus also make great companion plants? In this article, we'll explore the benefits of planting dianthus alongside other garden favorites.

Dianthus Companion Plants: The Basics

When it comes to companion planting, the goal is to create a harmonious environment where plants can support each other's growth and health. Dianthus are particularly good candidates for companion planting because they have shallow root systems and don't compete aggressively for nutrients or water. Here are some of the best plants to pair with dianthus:

1. Lavender

Lavender and dianthus make a perfect match. Both plants prefer well-draining soil and plenty of sun, and they complement each other nicely with their similar heights and colors. Plant them together in a sunny spot and enjoy the soothing scent of lavender intermingled with the spicy aroma of dianthus.

How to Plant

To plant dianthus and lavender together, choose a sunny location with well-draining soil. Plant the dianthus first, spacing them about 12 to 18 inches apart. Then add the lavender plants, spacing them evenly around the dianthus. Water thoroughly after planting.

2. Roses

Roses and dianthus are a classic pairing. The bright colors of dianthus complement the delicate beauty of roses, while their shallow roots don't compete with the deeper root systems of the rose plants. Plant dianthus around the base of your rose bushes to add a pop of color and interest.

How to Plant

To plant dianthus around roses, choose a sunny location with well-draining soil. Space the dianthus evenly around the base of the rose bushes, leaving enough room for both plants to grow. Water thoroughly after planting.

3. Salvia

Salvia is another great companion plant for dianthus. Both plants prefer full sun and well-draining soil, and they have similar heights and growth habits. Salvia also attracts pollinators like bees and butterflies, which can help to boost the health and productivity of your garden as a whole.

While lavender, roses, and salvia are some of the best companion plants for dianthus, there are many other options to consider. Here are a few more ideas:
