Ideal Companion Plants for Jack-in-the-Pulpit

The selection of companion plants for Jack-in-the-Pulpit should focus on species that share similar woodland habitat requirements and offer synergistic benefits.

Shade-Tolerant Groundcovers

Groundcovers help retain soil moisture, suppress weeds, and create a lush carpet beneath taller plants.

Wild Ginger (Asarum canadense): With its large, heart-shaped leaves, wild ginger provides excellent ground cover and prefers the same moist, shady conditions as Jack-in-the-Pulpit. It also helps deter deer and slugs.
Foamflower (Tiarella cordifolia): This delicate woodland native boasts attractive, lobed foliage and airy, white flower spikes in spring. It thrives in shade and moist soil, creating a beautiful textural contrast.
Partridgeberry (Mitchella repens): A low-growing evergreen groundcover, partridgeberry features small, rounded leaves and produces attractive red berries in the fall. It tolerates shade and acidic soil, making it an excellent choice.

Spring Ephemerals

Many woodland wildflowers are ephemerals, meaning they complete their life cycle (bloom and leaf out) in early spring before the canopy of deciduous trees fully closes. They provide early season interest and benefit from the moisture and cool soil of early spring.

Bloodroot (Sanguinaria canadensis): Known for its single, pure white flower that emerges before its distinctive blue-green leaves, bloodroot is a quintessential spring ephemeral that thrives in the same conditions as Jack-in-the-Pulpit.
Trillium (Trillium spp.): The elegant beauty of Trillium, with its characteristic three-leaved whorl and striking solitary flower, is a hallmark of healthy woodland gardens. Various Trillium species are excellent companions, adding to the spring display.

Mayapple (Podophyllum peltatum): This distinctive plant produces a single nodding white flower under its umbrella-like leaves. It spreads to form colonies and provides good ground cover in shady, moist areas.

Ferns for Texture and Shade

Ferns are indispensable in a woodland garden, providing lush texture, varying shades of green, and excellent shade.

Maidenhair Fern (Adiantum pedatum): Its delicate, fan-shaped fronds on black stems add an airy, elegant touch. Maidenhair fern prefers moist, humus-rich soil and shade.

Ostrich Fern (Matteuccia struthiopteris): This tall, dramatic fern unfurls large, vase-shaped fronds, creating a bold statement. It thrives in moist, shaded conditions and can help fill in gaps.
Christmas Fern (Polystichum acrostichoides): An evergreen fern, Christmas fern provides year-round color and texture. Its leathery fronds remain attractive through winter, offering visual interest when other plants are dormant.

Shade-Tolerant Perennials for Extended Bloom

While spring ephemerals offer early season beauty, incorporating plants with later bloom times can extend the garden’s interest.

Coral Bells (Heuchera spp.): Renowned for their stunning foliage in shades of purple, amber, and green, coral bells also produce delicate, airy flower spikes that attract hummingbirds and pollinators. They prefer shade and well-drained soil.
Hosta (Hosta spp.): With their diverse leaf shapes, sizes, and colors, hostas are woodland garden staples. They provide excellent ground cover and tolerate shade well. Their late-season blooms are also attractive to pollinators.
Bleeding Heart (Dicentra spectabilis): The iconic heart-shaped flowers of bleeding heart are a beloved sight in spring and early summer. It prefers moist, shady conditions and can complement the texture of Jack-in-the-Pulpit.

Aesthetic Appeal

The layered textures, varying shades of green, and staggered bloom times of a well-chosen companion planting scheme create a dynamic and visually captivating woodland garden. The unique structure of the Jack-in-the-Pulpit stands out amidst the softer forms of ferns and the ground-hugging nature of other woodland wildflowers.

Establishing Your Woodland Garden: Practical Steps

Creating a successful woodland garden with Jack-in-the-Pulpit and its companions involves careful planning and execution.

Site Selection and Preparation

Identify a suitable location: Choose an area that receives dappled shade or consistent partial shade throughout the day. Observe the light patterns in your chosen spot.

Assess soil conditions: Test your soil for pH and drainage. Amend heavy clay soils with plenty of compost and organic matter to improve drainage and fertility. Sandy soils can benefit from added compost to increase water retention.
Clear the area: Remove any invasive weeds or unwanted vegetation. Avoid disturbing existing beneficial soil organisms as much as possible.

Planting Techniques

Planting depth: Plant Jack-in-the-Pulpit corms at a depth of about 3-4 inches, with the pointed end facing upwards.

Spacing: Ensure adequate spacing between plants to allow for mature growth and air circulation. Refer to individual plant tags or descriptions for specific recommendations.
Layering: Plant taller species towards the back or center of beds, with shorter groundcovers and ephemerals at the front or edges. Place ferns strategically to create visual interest and provide shade.
Watering: Water thoroughly after planting to settle the soil and encourage root establishment.

Ongoing Care and Maintenance

Watering: Maintain consistent moisture, especially during dry periods. Water deeply and less frequently rather than shallowly and often, encouraging deeper root growth.
Mulching: Apply a layer of organic mulch, such as shredded leaves or compost, around your plants. This helps retain moisture, suppress weeds, and regulate soil temperature.
Fertilizing: Woodland plants generally do not require heavy fertilization. A top-dressing of compost or a light application of a balanced organic fertilizer in early spring is usually sufficient.

Pest and Disease Monitoring: Regularly inspect your plants for any signs of pests or diseases. Early detection and intervention are key. Generally, healthy plants in the right conditions are more resistant.
Leaf Litter: Allow fallen leaves to remain on the garden floor in the fall. This natural mulch is highly beneficial for woodland plants, providing nutrients and habitat for beneficial organisms.
