If you’re planning to start seeds or grow a bountiful vegetable garden this year, companion planting is a strategy worth considering. Think of companion planting as creating partnerships in your garden.
Certain flowers naturally deter harmful pests, keeping your vegetables safe, while others attract beneficial insects like pollinators or predators of garden pests.
Here are the best companion flowers for your vegetable garden.
Borage
Borage is a hardy, low-maintenance plant that brings more than beauty to your vegetable garden. Its delicate purple flowers are a magnet for pollinators like bees and butterflies, which is important for fertilizing certain vegetable plants and ensuring better yields. Borage pairs exceptionally well with crops like tomatoes, squash, strawberries, and zucchini.
Beyond attracting pollinators, borage also lures beneficial insects such as lacewings and parasitic wasps that help keep pest populations in check. These natural predators target harmful pests like aphids and hornworms, reducing the need for chemical interventions and supporting a healthier garden ecosystem.
One of the most impressive features of borage is its ability to self-seed, meaning it can return year after year without much effort on your part. However, this quality can also make it quite prolific, so it’s a good idea to thin out unwanted seedlings in early spring to prevent overcrowding.
Calendula
Calendula has a distinctive musky fragrance that will repel hornworms, aphids, and flea beetles from your vegetable plot. They are easy to grow and will form a mat of colorful flowers.
