If you’ve been thinking about installing a rain garden or adding to your existing landscape, the annual Milwaukee Metropolitan Sewerage District (MMSD) Spring Plant Sale is the place to start! Native plants can be pre-ordered once the sale opens in February 2025 with in-person plant pickup at our Headquarters in June 2025. Sign up for our newsletter to be the first to know when the plant sale opens. 

Choose from dozens of hardy native wildflowers and grasses to take the guesswork out of what to buy for a beautiful rain garden. Rain gardens can help reduce the risk of ​​​​​sewer overflows and water pollution by naturally absorbing stormwater runoff from hard surfaces into the ground.
