In raised bed gardens, the concept of companion planting is widely practiced to maximize the growth and health of plants. Companion plants are chosen based on their mutually beneficial relationships, such as repelling pests, attracting pollinators, providing shade or support, and improving soil fertility. When it comes to edible flowers, there are several potential companion plants that can enhance their growth and overall garden productivity.
1. Marigolds
Marigolds are often considered the go-to companion plant for edible flowers in raised bed gardens. These vibrant flowers not only add beauty to the garden but also repel pests like aphids, nematodes, and whiteflies. Their strong scent and natural insecticidal properties make them an excellent choice for deterring harmful bugs from attacking the edible flowers.
2. Nasturtiums
Nasturtiums are another popular companion plant for edible flowers. These colorful flowers not only attract beneficial insects like bees and hoverflies, but their leaves can also serve as a trap for aphids, protecting the edible flowers from infestation. Additionally, nasturtiums have trailing growth habits, which can provide shade and reduce soil evaporation, benefiting the nearby plants.
3. Chives
Chives are herbaceous perennial plants that make excellent companion plants for edible flowers. They repel pests like aphids, carrot flies, and Japanese beetles, making them great protectors of the garden. Furthermore, the purple flowers of chives are edible and can be a delightful addition to salads and other dishes.
4. Calendula
Calendula, also known as pot marigold, is a versatile flower that can serve as both an ornamental and companion plant. Its bright yellow and orange flowers attract pollinators like bees and butterflies, aiding in the pollination of edible flowers. Moreover, calendula flowers are edible and can be used in culinary preparations or dried for herbal infusions.
5. Borage
Borage is an herbaceous plant with attractive blue flowers that can be a beneficial companion to edible flowers. Its flowers are rich in nectar, attracting pollinators like bees and beneficial insects that assist in the garden's overall health. Borage is also known for its helpful nature in repelling pests like tomato hornworms and cabbage worms.
6. Sweet Alyssum
Sweet alyssum is a low-growing flowering plant that can act as a beneficial ground cover for raised bed gardens. Its tiny white or purple flowers produce a sweet fragrance that attracts pollinators, including bees and hoverflies. The presence of sweet alyssum can reduce soil erosion, conserve moisture, and provide a microclimate that benefits the neighboring edible flowers.
7. Yarrow
Yarrow is a perennial herb with aromatic fern-like leaves and clusters of small, daisy-like flowers in various colors. It attracts beneficial insects like ladybugs and lacewings, which help control aphids and other garden pests. Yarrow's deep roots can also help improve soil structure and nutrient cycling, benefiting the overall health of raised bed gardens.
Conclusion
Incorporating companion plants into raised bed gardens not only enhances the aesthetic appeal but also promotes healthier and more productive growth of edible flowers. The potential companion plants mentioned above, including marigolds, nasturtiums, chives, calendula, borage, sweet alyssum, and yarrow, offer various benefits such as pest repellence, pollinator attraction, shade provision, soil improvement, and soil erosion control. By incorporating these companion plants, gardeners can create a harmonious and thriving environment for their edible flower beds.
