Wisconsin’s climate ranges from the cold, snowy north to the slightly milder southern regions. Here’s a closer look at the zones in Wisconsin and some shade-loving plants that will thrive in each:

• Zone 3:

  
  

  Found in northern Wisconsin and higher elevations, where winter temperatures can drop to -40 to -30°F. For these colder regions, consider these hardy, shade-tolerant plants:

  
  

  • Siberian Iris (Iris sibirica): This tough perennial thrives in cold climates, offering vibrant blooms that stand out in shady spots.

  • Goatsbeard (Aruncus dioicus): Resembling a giant Astilbe, Goatsbeard is perfect for shade gardens, with tall, feathery plumes of white flowers.

  • Bunchberry (Cornus canadensis): A low-growing groundcover, Bunchberry offers white flowers in spring and bright red berries in late summer, thriving in the cool, shaded areas of Zone 3.

    
    

• Zone 4:

  
  

  Covers much of central Wisconsin, with winter temperatures ranging from -30 to -20°F. This zone is ideal for a variety of hardy shade plants:

  
  

  • Hostas (Hosta spp.): A classic choice for shade gardens, Hostas offer lush foliage in a range of colors, from deep green to variegated patterns.

  • Solomon’s Seal (Polygonatum spp.): Known for its graceful, arching stems and bell-shaped flowers, Solomon’s Seal is perfect for shaded woodland gardens.

  • Lungwort (Pulmonaria spp.): With its spotted leaves and clusters of pink, blue, or white flowers, Lungwort adds texture and color to shady areas.

    
    

• Zone 5:

  
  

  Found in southern Wisconsin, where winter temperatures range from -20 to -10°F. Ideal for slightly milder climates, these shade-tolerant plants will flourish:

  
  

  • Brunnera (Brunnera macrophylla): Also known as Siberian Bugloss, this plant features heart-shaped leaves and delicate, forget-me-not-like blue flowers.
