Growing Jack-in-the-Pulpit
Choose the Right Location:
- Light: Jack-in-the-Pulpit thrives in partial to full shade, mimicking the dappled light of its native woodland habitat.
- Soil: The plant prefers rich, well-draining soil with a high organic matter content. A slightly acidic to neutral pH is ideal.
Planting:
- When to Plant: The best time to plant Jack-in-the-Pulpit is in the fall or early spring.
- Spacing: Plant corms or young plants about 1-2 feet apart to give them room to grow.
- Depth: Plant corms about 3-4 inches deep, with the pointed end facing upwards.
Caring for Jack-in-the-Pulpit
Watering:
- Keep the soil consistently moist, especially during the growing season. Avoid waterlogging, as this can cause root rot.
Mulching:
- Apply a layer of mulch around the plants to retain soil moisture, suppress weeds, and provide organic matter as it decomposes.
Fertilizing:
- Incorporate compost or well-rotted manure into the soil before planting. Additional feeding is generally not necessary if the soil is rich in organic matter.
Pests and Diseases:
- Jack-in-the-Pulpit is relatively pest-free. However, watch out for slugs and snails, which can damage young plants.
Winter Care:
- In colder regions, apply a thick layer of mulch in late fall to protect the corms from freezing temperatures.
Propagation:
- Jack-in-the-Pulpit can be propagated by seed or by dividing mature clumps in the fall. Seeds should be sown immediately after harvesting, as they require a period of cold stratification.
Additional Tips
- Wildlife: While Jack-in-the-Pulpit is toxic to humans if ingested, it is generally not harmful to wildlife. The bright red berries are eaten by birds, which help in seed dispersal.

6 Steps for Propagating Jack-in-the-Pulpit Plant
Propagating Jack-in-the-Pulpit (Arisaema triphyllum) can be done through seeds or by dividing the corms. Here are the steps for both methods:
Propagating by Seeds
Harvesting Seeds:
- In late summer to early fall, collect the bright red berries from mature plants. Each berry contains several seeds.
Cleaning Seeds:
- Remove the seeds from the berries and wash off the pulp. The pulp can inhibit germination, so ensure the seeds are clean.
Cold Stratification:
- Place the seeds in a plastic bag with a moist medium like peat moss or vermiculite. Seal the bag and refrigerate for at least 60-90 days to mimic winter conditions. This process is called cold stratification and is necessary for seed germination.
Sowing Seeds:
- After stratification, sow the seeds in pots or seed trays filled with a well-draining, rich soil mix. Press the seeds lightly into the soil and cover them with a thin layer of soil.
Germination:
- Place the pots in a cool, shaded area and keep the soil consistently moist. Germination can take several weeks to months. Patience is key, as Jack-in-the-Pulpit seeds can be slow to germinate.
Transplanting:
- Once the seedlings are large enough to handle, transplant them into individual pots or directly into the garden in a shaded, moist area. Ensure they have ample space to grow.
Propagating by Division
When to Divide:
- The best time to divide Jack-in-the-Pulpit corms is in the fall, after the plant has finished its growing season and the foliage has died back.
Digging Up the Plant:
- Carefully dig around the base of the plant to avoid damaging the corms. Lift the clump out of the ground.
Separating Corms:
- Gently separate the corms. Each division should have at least one bud or growing point. If there are small offsets (baby corms) attached to the main corm, you can gently break them off and plant them separately.
Replanting:
- Replant the divided corms at the same depth they were originally growing, about 3-4 inches deep, with the pointed end facing upwards. Space them 1-2 feet apart.
Watering:
- Water the newly planted corms thoroughly and keep the soil consistently moist. Mulch around the plants to retain moisture and provide winter protection.
Additional Tips
- Patience: Whether growing from seeds or divisions, Jack-in-the-Pulpit can take some time to establish and bloom. Be patient and provide consistent care.
- Labeling: If you are growing different varieties or from seeds, label your plants to keep track of their progress.
By following these steps, you can successfully propagate Jack-in-the-Pulpit plants and enjoy their unique beauty in your garden.
