Enchanting Color Schemes

Use color theory to create gardens that evoke different moods and emotions

Cool Waters

Blues combined with whites create a refreshing, tranquil garden reminiscent of water and sky.

  • White Phlox

Verdant Textures

Various shades of green with different leaf textures create depth even without flowers.

  • Japanese Forest Grass (Hakonechloa)
  • Hosta
  • Ferns
  • Heuchera

Sunset Glow

Warm oranges, yellows, and reds create an energetic, vibrant garden that glows in evening light.

  • Coreopsis
  • Red Hot Poker (Kniphofia)
  • Black-eyed Susan (Rudbeckia)
  • Lantana

Strategic Height Layering

Create garden beds with visual depth by thoughtfully arranging plants of different heights

Tall ornamental grasses in a garden
Tall (Over 3 feet)

Background Layers

Place the tallest plants at the back of borders (or center of island beds) to create a dramatic backdrop without obscuring shorter plants.

Suggested Plants:
  • Ornamental Grasses (Miscanthus, Pennisetum)
  • Delphinium
  • Joe Pye Weed (Eutrochium)
  • Hollyhock (Alcea)
Medium-height Echinacea and Salvia plants
Medium (1-3 feet)

Middle Layers

These plants bridge the gap between tall and short varieties, creating a smooth transition and filling in the garden's middle ground.

Suggested Plants:
  • Coneflower (Echinacea)
  • Salvia
  • Shasta Daisy (Leucanthemum)
  • Coral Bells (Heuchera)
Low-growing Sedum as ground cover
Short (Under 1 foot)

Foreground Layers

Low-growing plants for the front of borders or as ground covers that soften edges and prevent soil erosion.

Suggested Plants:
  • Creeping Thyme (Thymus)
  • Sedum
  • Dianthus
  • Sweet Alyssum (Lobularia)

Pro Tip: The Rule of Thirds

In a well-designed garden bed, consider allocating approximately:

1/3

Tall background plants

1/3

Medium middle-layer plants

1/3

Short foreground plants

This general guideline creates visual balance and ensures all plants receive appropriate sunlight while creating an appealing, layered appearance.
