The encroachment of invasive wetland and aquatic plants poses a substantial threat to the delicate
balance of ecosystems, jeopardizing biodiversity and disrupting natural habitats.
The proliferation of species like Phragmites australis, Hydrilla verticillata, and
Purple Loosestrife has sparked growing concerns about the long-term environmental
impact on wetlands and aquatic environments.
This article delves into the pressing need for addressing these invasions and explores effective
landscaping alternatives to replace common invasive species.
By emphasizing the importance of sustainable practices and promoting the use of native plant
species, we aim to provide a comprehensive guide for individuals, communities, and landscaping
professionals seeking ecologically responsible solutions.
Through this exploration, we aspire to contribute to the preservation of the health and vitality of
wetland and aquatic ecosystems while fostering a deeper understanding of the role landscaping can
play in mitigating environmental challenges.
Incorporating aquatic and wetland plants into your water gardens, ponds, and rain gardens serves
multiple purposes, such as oxygenating the water, providing shelter and sustenance for wildlife,
enhancing aesthetic appeal, and supporting pollinators.
The selection of plants for rain gardens plays a pivotal role in their functionality to mitigate
Through time, we’ve discovered that numerous invasive plants introduced to our gardens adversely
impact native species by encroaching into natural areas.
This publication recommends alternative plant choices for several reasons:
• Exhibit desirable ornamental and environmental characteristics.
• Thrive successfully in the Upper Midwest region.
• Accessible from reputable nurseries and garden centers.
• Pose a minimal risk of escaping cultivation or causing harm.
Choosing these alternatives ensures the continued beauty and ecological integrity of your garden
while contributing to the conservation of native plant species.
