Canadian Arrowhead is a hardy plant that is easy to grow and maintain. It prefers full sun to partial shade and can tolerate a wide range of soil types, as long as the soil is consistently moist. It is also tolerant of fluctuating water levels, making it a great choice for wetlands and marshy areas.

Canadian Arrowhead is also a popular choice for wetland restoration projects, as it is a native plant that is well-suited for the environment. It helps to stabilize the soil, reduce erosion, and improve water quality by filtering pollutants and excess nutrients from the water.

However, it can also be considered as an invasive species in some regions, if not controlled in time. It can outcompete native plants and disrupt the natural balance of wetland ecosystems. Therefore, it is important to be aware of the potential invasive nature of Canadian Arrowhead and to plant it responsibly, avoiding to plant it in areas where it can spread uncontrollably.
