At Olson’s Nursery, we offer a wide selection of locally grown plants chosen to thrive in Wisconsin’s climate. From hardy perennials and flowering shrubs to annuals, natives, and pollinator-friendly plants, our collection is curated to perform well in home landscapes throughout Southeast Wisconsin. Whether you’re planting a new garden or refreshing an existing space, you’ll find healthy, high-quality plants ready for success
Our annual flowers are perfect for adding quick color to containers, hanging baskets, window boxes, garden beds, and porch displays. Whether you love bold, eye-catching combinations or soft, classic palettes, our annuals make it easy to create a fresh look every season.
From spring blooms and summer texture to vibrant fall color, perennial deciduous shrubs offer four seasons of interest while providing privacy, foundation structure, and habitat for birds and pollinators. These shrubs shed their leaves in winter but return each spring with fresh growth and renewed beauty.

Peonies are classic, long-lived perennials known for their large, fragrant blooms and exceptional cold hardiness. Their bold blooms make them a favorite for perennial borders, foundation plantings, and cut flower gardens. Once established, peonies require very little maintenance and can live for decades
Evergreen shrubs are the backbone of a beautiful landscape — providing year-round color, structure, and privacy, even in the depths of a Wisconsin winter. At Olson’s Nursery, we carefully select evergreen shrubs that are hardy, dependable, and proven performers in our local climate.
Celebrate autumn with vibrant fall mums from Olson’s Nursery. Our locally grown chrysanthemums are packed with rich color, long-lasting blooms, and strong branching—perfect for porches, patios, containers, and garden beds. Available in a wide range of classic fall shades including yellow, bronze, orange, red, pink, and bi-color blends, our mums deliver instant curb appeal from early fall through frost

Bring life indoors with beautiful, easy-to-love houseplants. Houseplants do more than decorate a space. They add warmth, improve mood, and create a calming connection to nature year-round.
