Plants which attract dragonflies

If you want to attract dragonflies to your home, you’ll have to create a home for them too. A manmade pond is great for dragonflies, provided it’s well balanced and suitable for dragonflies in the egg and nymph stages. Make sure that your pond is a proper depth – not so deep that plants can’t take root in the center. Place flat rocks around it as well so dragonflies can perch on them. Your dragonfly pond should also be shielded from strong winds and gusts.

Aquatic plants, whether floating or submerged, can attract dragonflies. Different plants are suitable for different stages of a dragonfly’s life cycle.

Underwater Plants
Plants that are submerged can provide safety from dragonfly’s predators, making it necessary for a dragonfly pond. Dragonfly nymphs are vulnerable to predators, and these plants provide them with refuge, enabling them to make it to adulthood. One type of submerged plant that would be great for a dragonfly pond is the Dwarf Sagittaria, which is commonly found in ponds, lagoons, as well as freshwater streams. This ornamental plant can do well in zones 6 -10. Another option is the Brazilian Waterweed, which can survive zones 5 to 11.

Floating Plants
Floating plants don’t need to be able to take root in the pond. They are essential to your dragonfly pond however, because certain species of dragonfly lay eggs on the plants’ stems or undersides. Water lilies are an excellent option for water plants, and different types can survive in different areas. Just check which one is most appropriate for your climate.

Emergent Plants
Emergent plants are like submerged plants in the sense that they need to be rooted on the bottom of the pond. However, they are like floating plants because their stems and leaves emerge from the water. Emergent plants are an essential feature of dragonfly ponds because dragonfly larvae use them to get to the pond surface when they reach adulthood.

Shoreline Plants
Marsh plants, also known as shoreline plants, are used by adult dragonflies for perching, as well as egg-laying. These hydrophilic plants do best in damp, moist soil. Examples of these are cattails, Arrowhead, Water Lilies, and Blue Flag.

You should place your pond in an area that gets full sun because dragonflies are cold blooded. This will also allow sunlight to make its way to the aquatic life below. Make sure to prevent the floating plants from covering most of the pond’s surface as well to allow sunlight to go through.

When creating your dragonfly pond, make sure not to put any fish in them. Though fish are a lovely addition to a pond, they eat dragonfly nymphs. Avoid using pesticides or herbicides around your pond as well, as this might kill dragonfly nymphs – and dragonflies will end up avoiding the pond because of the tainted water. Also, don’t mow the area around your dragonfly pond. Allow the plants to become well established so they can serve as perching places for the dragonflies.
