Rain Gardens

The Rain Garden Plant Sale is Open!

Rain gardens help reduce the risk of sewer overflows and water pollution by absorbing stormwater runoff from hard surfaces into the ground naturally. Since 2006, the Milwaukee Metropolitan Sewerage District (MMSD) and Agrecol Native Seed and Plant Nursery have offered a rain garden plant sale to customers within MMSD’s service area. Plants are provided at a reduced price; up to a 50% discount compared to retail prices. Order now through March 31st* at the online store and pick-up your plants on Saturday, June 10th at MMSD

*Plant supplies are limited for this plant sale. Once plants SELL OUT, the SALE WILL CLOSE! 

In addition, to the plant sale, MMSD is offering FREE rain garden webinars with gardening expert, Melinda Myers, and a design workshop where you can learn about rain gardens, plant selection, and plant care. Details on these workshops will be announced soon.

For more information on workshops and the details of the plant sale visit our Plant Sale details page.

What is a Rain Garden?

Rain gardens help reduce water pollution by collecting rain mainly from roofs, driveways, or other hard surfaces, and absorbing the water into the ground naturally. They are typically planted with wildflowers or native plants that have deep roots, which help to soak up more water. They can be placed near downspouts on homes (although away from building foundations and sewer laterals), and offer many benefits.
