Why Alternatives?

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.
