11 Companion Flowers for Zinnia Beds That Attract Pollinators Instantly

Nasturtiums (Tropaeolum majus)

Trailing orange nasturtiums spilling over a raised bed edge next to healthy zinnia plants.

I’ll never forget the spring I planted a gorgeous border of trailing nasturtiums along the edge of my raised zinnia beds, mostly because I wanted to toss the pretty edible flowers into my summer salads. I had no idea I was actually setting up a genius, microscopic battleground that would save my entire garden.

By June, my nasturtium leaves were absolutely covered in tiny black aphids, but when I checked my precious zinnias right next to them, the stems were completely clean, green, and thriving. It was a total lightbulb moment for me.

The Sacrificial Trap Crop

When you introduce nasturtiums into your flower layout, you are utilizing a brilliant organic gardening technique known as trap cropping. For some bizarre reason, destructive pests like aphids and whiteflies find the sap of Tropaeolum majus completely irresistible—even more than your prized zinnias.

By planting them closely together, the nasturtiums act as a sacrificial shield, drawing the bad bugs away from your main showstoppers. It keeps your cutting flowers looking flawless for the vase without ever needing a single drop of toxic chemical sprays.

Spilling Over the Edges

Beyond their secret agent pest work, nasturtiums bring an absolute mood to the overall design of your garden beds. Their beautiful, rounded lily-pad leaves and bright, trumpet-shaped flowers have a lovely trailing habit that looks incredible spilling over the edges of raised beds or borders.

They are incredibly low-maintenance and actually prefer poor, lean soil, which prevents them from hogging the rich nutrients your heavy-feeding zinnias need to grow. They just want to bask in the hot sun, keep the bugs busy, and look absolutely effortless.

Honestly, watching those vibrant orange petals cascade down the side of a wooden garden box is enough to make any plant lover swoon, but we have another companion that brings a totally different, magical element to the sky. Let’s keep this momentum going and look at a dreamy purple flower that literally floats in the wind, so hit that next button right below!
