Designing Your Woodland Garden with Jack-in-the-Pulpit

Creating a harmonious planting scheme involves considering visual elements and practical plant needs.

Layering and Height Variation

Mimic the natural woodland structure by layering plants. Taller ferns or Hostas can form the mid-story, while groundcovers fill the understory. Place Jack-in-the-Pulpit strategically within these layers, ensuring it receives adequate dappled light.

Color and Texture Contrast

Juxtapose the unique structure of Jack-in-the-Pulpit with plants that offer contrasting foliage textures. The lacy fronds of ferns against the broad leaves of Hostas, or the delicate blooms of Foamflower against the robust form of Mayapple, create visual interest. Use the vibrant leaf colors of Heuchera to add pops of color.

Succession of Bloom

Plan for continuous blooming by selecting plants with staggered flowering times. This ensures that your woodland garden remains attractive from early spring through fall.

Consider Soil and Moisture Zones

When planting multiple species, group plants with similar soil and moisture requirements together. This simplifies care and ensures that each plant thrives. For example, place moisture-loving ferns and Astilbe in areas where moisture is consistently available.
