Companion Plants That Will Totally Thrive Next To Your Flourishing Cilantro

Herbs tend to be the easiest types of plants to find companions for, and cilantro (Coriandrum sativum) isn't any different. The plant already has so many natural abilities that it needs almost no help in the garden. In fact, cilantro is usually the one to offer some of its benefits to other plants growing near it. It can provide shade, entice pollinators, and it has simple growing requirements that allow it to adapt to different climates. What it can't live without is access to direct sunlight and well-draining soil.

The best reason to plant cilantro in a vegetable garden is because it attracts predatory insects. While the name sounds a bit frightening, these are just pollinators and other bugs that feed on the larvae of other insect species that threaten your edible plants. You're likely already familiar with many of them such as ladybugs, green lacewings, and parasitic wasps. Caring for your cilantro correctly and carefully considering the best place to plant it will reward you with a healthier garden throughout the growing season.

Carrots (Daucus carota var. sativus) are one of a few root vegetables that benefit from being grown next to cilantro. As we know, cilantro repels a variety of pests, including carrot rust flies, which are attacked by predatory insects that the herb attracts. Planted in the garden, these two edible plants tolerate growing side by side. Both enjoy bright direct sunlight and well-draining soil.

Okra (Abelmoschus esculentus) is a tall-growing plant that blooms with big and bright flowers, however, it is usually grown for its edible fruits that can be roasted, fried, or boiled. Typically okra plants don't require too much help in the garden unless you have a pest infestation. To combat this, you can plant your okra nearby fragrant herbs, like cilantro, to attract beneficial insects.

Zinnias (Zinnia spp.) are known for their varieties that have different heights, bloom types, petal colors, and tolerances to certain growing conditions. When choosing one to plant alongside your cilantro, we recommend any that grows taller than cilantro's average height of 1 to 2 feet tall. This ensures that your cilantro will get some shade during the growing season while your zinnias soak in all the heat.

Another nightshade species, pepper plants (Capsicum annuum) benefit from the presence of cilantro plants nearby as they deter common pepper threats. In the summer, your cilantro should go to flower just as the peppers start fruiting. So, beneficial bugs, like hoverflies and ladybugs, arrive to feed on nectar and pollen as well as pest larvae from aphids and mites.

Kale (Brassica oleracea, Acephala Group) is an annual leafy vegetable that grows best in well-draining and rich soil, like cilantro. As you may have already guessed, kale benefits from cilantro's pest-eating pollinators that come to its clusters of flowers. However, cilantro benefits from kale in other ways too. For example, because it typically grows taller than the salad ingredient, cilantro will shade it from the hot sun with its terminal umbels and dense foliage.

Similarly to zinnias, cosmo flowers (Cosmos bipinnatus) are tall-growing and long bloomers that thrive next to cilantro plants. Their thin stems and thread-like leaves make it possible for the herb to grow in more indirect sunlight, which keeps cilantro from bolting and becoming bitter. Keep in mind that cosmos and cilantro are annuals, so both will need to self-seed or be replanted each year.

Cabbage (Brassica oleracea var. capitata) is a well-known leafy vegetable that prefers direct sunlight and cool temperatures. Because of this, it usually isn't planted for summer growth as it would suffer under the heat. Instead, it's grown in the early part of spring or in the fall as the temperatures drop. Planted with cilantro, many of the beetles and aphids that feast on cabbage can be dealt with naturally.
