Wetland & Pond Garden
Wetland and pond gardens are designed to mimic a natural ecosystem found along the water's edge. In pond gardens, the water feature becomes the central focus, which can vary from expansive ponds to compact container ponds. The primary purpose of these gardens is to create harmonious spaces where water and plants coexist. Creating this ecosystem will welcome wildlife that might not otherwise inhabit the area. Native plants are a great addition to a pond garden because they help filter the water and stabilize the water's edge. Over time, pond gardens tend to naturally achieve balance. Adding native vegetation can accelerate this process, fostering a healthy ecosystem that supports beneficial insects, bacteria, and other animals.
To manage mosquito populations, consider introducing a pump or fountain to keep the water moving. Additionally, the presence of frogs or dragonflies can serve as natural mosquito control.
Key Elements of a Wetland/Pond Garden
Water Feature: The main component of the garden will be the water feature. Enhance the pond with additional features and textures. A small waterfall or strategically placed stones will draw the eye in.
Plants: Plants can be along the water's edge or growing in the pond itself. Opt for plants suited to damp or flood-prone conditions.
Wildlife: Wildlife such as frogs, salamanders, dragonflies, birds enjoying baths, and mammals drinking along the water's edge are drawn to these gardens. Avoid adding invasive species to your pond. Goldfish are commonly introduced into outdoor ponds, but they can become invasive. Keep your pond as natural and environmentally friendly as possible.
Moist Soil: Unlike rain gardens, which dry out between floods, wetland gardens stay wet. This makes them ideal for plants that thrive in wet conditions or standing water.
Native Plants for a Wetland/Pond Garden
These native to Ontario plants require moist soil to survive and thrive. While most of these species are best planted around the pond’s edges (will not tolerate standing water), some can grow directly in standing water.
Fully Submerged Plants
Plants that can be full submerged in the pond. Good for deeper areas of the pond.

Canadian Waterweed (Elodea canadensis): Full Sun
Pickerelweed (Pontederia cordata): Full Sun to Partial Shade
Sweet Flag (Acorus americanus): Partial Shade to Full Sun
Yellow Pond Lily (Nuphar lutea): Full to Partial Sun
Water Arum (Calla palustris): Partial to Full Sun
White Water Lily (Nymphaea odorata): Full to Partial Sun
Shallow Standing Water
Plants that can tolerate shallow standing water due to infrequent flooding. They prefer consistently moist soil. Will do well planted on pond edges.
