Choosing the right companion flowers for your vegetable garden does more than just add a splash of color—they can play a powerful role in creating a healthier, more productive growing space.
Many flowers naturally attract pollinators, draw in beneficial insects that prey on pests, and even help deter harmful bugs with their scent or structure. Some can improve soil health, while others may enhance the growth, yield, or flavor of nearby vegetables.
Here are 10 flowers you should consider planting next to your vegetables this season.
Nasturtiums (Tropaeolum majus)
Nasturtiums are a dual-purpose powerhouse in the vegetable garden. They attract pests like aphids and squash bugs away from your main crop, while also bringing in beneficial insects like hoverflies and predatory wasps.
Their trailing vines help cover bare soil, reducing weeds and retaining moisture in the ground, which is perfect for supporting your vegetables.
Cosmos (Cosmos bipinnatus)
Cosmos are easy to grow from seeds, with blooms appearing in about two months. They tolerate summer heat well and add height and movement to garden beds, attracting pollinators with their delicate, daisy-like flowers.
They prefer sunny spots and well-drained soil, and once established, they require minimal watering. The variety of colors—pink, white, red, orange, and purple—ensures a match for any garden theme.
Borage (Borago officinalis)
Borage is a magnet for pollinators and beneficial insects, which makes it a perfect companion for vegetables like squash. Its star-shaped flowers attract bees while also drawing in pest-eating insects like ladybugs.
Borage is especially effective in controlling aphids and hornworms. It self-seeds easily, so keep an eye on spreading.
Bee Balm (Monarda didyma)
Bee balm is a magnet for pollinators, especially hummingbirds and bees. It also helps to reduce the risk of fungal diseases that affect many vegetables. It grows in USDA zones 4 to 9 and thrives with moderate watering, full sun to partial shade.

These cheerful flowers are low-maintenance and grow quickly, offering both protection and pollination support as they spread across the garden bed.
Marigolds (Tagetes spp.)
Marigolds are one of the most well-known companion plants—and for good reason. Their strong scent repels a wide range of pests, including squash bugs, aphids, nematodes, and beetles that often target vegetables like tomatoes and squash.
