Companion Plants That Will Thrive Alongside Basil In The Garden

The basil plant (Ocimum basilicum) is popular in home gardens for its delicious leaves that have several uses in the kitchen. This herb, which is frequently used to flavor pasta, beef, and fish dishes, is one of the best companion plants out there. It has many friends in the plant kingdom and forms relationships with a variety of vegetables, flowers, and other herbs that could use some help during their growing season.

One of the reasons that basil makes a good companion plant is that its soil preference is the same as many other edible plants. It enjoys moist, rich, and well-draining garden soil that helps it produce the large and flavorful foliage we love. Additionally, its scent and flowers attract beneficial insects that will pollinate nearby plants while also repelling harmful bugs that snack on more palatable species like tomatoes and cabbage. 

However, these basil companions aren't taking advantage of the culinary herb. They're helping in their own way. Borage, for example, is reported to enhance basil plants' flavor and growth when planted nearby. Companion planting with basil has even more benefits than this. Check out our collection of plants you can grow alongside it to watch your herb and vegetable gardens thrive.

Though basil isn't great for growing alongside every herb, oregano (Origanum vulgare) can make for a good companion plant. By planting the two together, you allow both herbs to improve each other's pungent foliage for a more intense flavor. Not only does this trick work to give you a better-tasting harvest, but it also makes basil more effective at driving away harmful insects.

Asparagus (Asparagus officinalis) and basil are a great example of a mutually beneficial relationship between two companion plantings. When they are grown together, asparagus attracts ladybugs which are beneficial insects that feed on harmful aphids. At the same time, the smell of basil plants' leaves keeps asparagus beetles away, which eat the vegetable's foliage.

Though nasturtiums (Tropaeolum spp.) and basil aren't necessarily companion plants to one another, they can be planted together to protect other species in your garden. Nasturtiums are known for their fragrant flowers that lure in aphids and squash bugs. This keeps the feasting insects from eating other plants, but the blooms also bring in reinforcements. Aphid-eating pollinators and flies are attracted by nasturtiums and basil to make sure the harmful insects stay gone.

Borage (Borago officinalis) and basil plants grow well together for a few different reasons. For one, they attract many of the same insects, namely pollinators, that may help to increase the health of much of your garden. Another reason is that they are both edible. Keeping borage alongside basil and other herbs like dill and parsley makes harvesting simple. Finally, they also like to grow in the same kind of conditions.

Parsnips (Pastinaca sativa), which are a close relative of carrots, can also benefit from being planted near basil. The low-maintenance root vegetable grows in moist soil and direct sunlight, much like the herb, so they end up being good partners. During the warmest parts of the season, a basil plant can protect parsnips from carrot flies that are repulsed by the smell of its leaves.
