Understanding Shade in the Garden

Not all shade is the same. Before choosing plants for your garden, it’s important to understand how much sunlight an area actually receives. A plant that thrives in light shade may struggle in deep shade, while some shade-loving plants perform best with a little morning sun.

Light Shade (Bright Shade)

Sunlight: 4–6 hours of sun per day, usually morning sun or filtered sunlight.

Common Locations:

  • East-facing gardens

  • Areas beneath trees with open canopies

  • Spots that receive morning sun and afternoon shade

Characteristics:

  • Bright conditions without intense afternoon heat

  • Many flowering shade plants perform well here

  • Soil tends to dry more slowly than in full sun

Plants That Thrive:

  • Hosta

  • Heuchera (Coral Bells)

  • Astilbe

  • Japanese Forest Grass

  • Brunnera

Medium Shade (Partial Shade)

Sunlight: 2–4 hours of direct sun per day, often filtered through trees.

Common Locations:

  • North or northeast sides of buildings

  • Under mature deciduous trees

  • Areas shaded for much of the day

Characteristics:

  • Cooler temperatures

  • Less intense light

  • Ideal for many woodland plants

Plants That Thrive:

  • Hellebores

  • Ferns

  • Pulmonaria (Lungwort)

  • Epimedium

  • Bleeding Heart

Deep Shade (Full Shade)

Sunlight: Less than 2 hours of direct sun per day.

Common Locations:

  • Under dense evergreen trees

  • North side of buildings or fences

  • Areas between structures with very limited sunlight

Characteristics:

  • Cool and often moist

  • Limited flowering options

  • Foliage becomes the primary source of color and texture

Plants That Thrive:

  • Ferns

  • Hosta

  • Japanese Forest Grass

  • Sweet Woodruff

  • Vancouveria (Inside-Out Flower)

Dappled Shade

Sunlight: Sunlight filtered through tree branches, creating shifting patterns of sun and shade throughout the day.

Common Locations:

  • Beneath Japanese maples

  • Under large deciduous trees

  • Woodland gardens

Characteristics:

  • Often considered the “goldilocks” of shade conditions

  • Many shade-loving plants grow exceptionally well

  • Mimics natural woodland environments

Plants That Thrive:

  • Hellebores

  • Hosta

  • Brunnera

  • Astilbe

  • Trillium

A Pacific Northwest Gardening Tip

Many gardeners think they have “shade” when they actually have light shade or dappled shade. Before selecting plants, spend a sunny day observing the area and note how many hours of direct sunlight it receives. You’ll have much better success matching plants to your site conditions.

Remember: Morning sun is gentler than afternoon sun. A location with four hours of morning sun may still be considered a shade garden, while four hours of hot afternoon sun can be challenging for many shade-loving plants.

The best shade gardens combine a variety of foliage colors, textures, and bloom times to create interest throughout the year—even in the darkest corners of the Pacific Northwest garden. 🌿
