Plant Overview
Oplopanax horridus, commonly known as devil’s club, is a perennial shrub belonging to the Araliaceae family. This plant is native to the western coastal regions of North America, particularly found in areas such as Alaska, British Columbia, and parts of the Pacific Northwest, including Washington and Oregon.
Morphology
Devil’s club typically grows to heights of 3 to 10 feet (1 to 3 meters). The plant is characterized by its distinctive large, palmate leaves, which can measure up to 12 inches (30 centimeters) wide. The leaves have a spiny texture and are composed of 5 to 7 lobes. The stem of Oplopanax horridus is notable for its thick, spiny protrusions, which can seem intimidating and contribute to the plant’s common name.
In the summer, devil's club produces clusters of small, white to greenish-white flowers that are borne on erect panicles. The fruits that follow are small, red berries that can be toxic if consumed in large quantities due to their saponin content.
Habitat and Ecology
Devil’s club thrives in moist, shady environments, often found in forest understories, along streams, and in damp, nutrient-rich soils. It plays a vital role in its ecosystem, providing habitat and food for various wildlife species. It also serves as an important medicinal plant in the traditional practices of many Indigenous peoples in its native range.
Medicinal Uses
Oplopanax horridus has a long history of use in traditional medicine. The roots, bark, and leaves are often utilized for their purported health benefits. Traditionally, devil’s club has been used to treat a variety of ailments, including infections, digestive issues, and inflammation. It is also recognized for its potential to help manage blood sugar levels and support overall immune system health. However, more scientific research is needed to fully understand its efficacy and safety.
Conservation Status
While Oplopanax horridus is not universally classified as endangered, it faces threats from habitat destruction, particularly due to logging, urban development, and invasive species. Sustainable harvesting practices and conservation efforts are important to ensure the continued survival of this plant in its native habitats.
Cultural Significance
In addition to its medicinal uses, devil’s club holds cultural significance for several Indigenous peoples, who use it in ceremonial practices and rituals. The plant is often revered for its protective qualities and is sometimes utilized in crafting tools and items.
In summary, Oplopanax horridus is a unique and ecologically significant plant with notable medicinal properties and cultural importance, making it a fascinating subject of study within botany and ethnobotany.

Detailed Care Instructions
Here are some steps to help you grow Oplopanax Horridus (also known as Devil's Club) plant:
- Gather seeds or purchase them from a reputable source. Devil's Club seeds can be challenging to find, so be prepared for a potential search.
- Prepare a suitable growing environment. Devil's Club predominantly grows in moist, cool, and shaded areas. Mimicking these conditions will help the plant thrive. Select a location that receives partial shade and has well-draining soil.
- Scarify the seeds. Devil's Club seeds have a hard outer covering, and scarification helps break through this coating, allowing water to penetrate for germination. Use sandpaper or a file to gently rub the surface of the seeds until they are slightly scratched.
- Plant the seeds in pots or seed trays filled with a mix of equal parts peat moss and perlite. Bury the seeds about 1/4 to 1/2 inch deep in the soil, then water thoroughly.
- Maintain a consistent moisture level. Devil's Club prefers constantly moist soil, so it's important to keep the soil consistently damp but not waterlogged. Use a spray bottle to mist the soil if necessary.
- Provide the right temperature conditions. Devil's Club thrives in cool temperatures around 50-65°F (10-18°C). Maintain a cooler room or greenhouse environment to ensure optimal growth.
- Be patient. Devil's Club can have variable germination times, even up to several months. Keep the soil consistently moist and provide consistent cool temperatures to improve germination success.
- Transplant seedlings. Once the seedlings have developed multiple sets of leaves and are sturdy enough, they can be transplanted into larger pots or directly into your garden. Choose a location that still offers partial shade and moist soil for optimal growth.
- Continue to provide proper care. Devil's Club plants appreciate regular watering, especially during dry spells. Mulching around the base of the plant helps retain moisture and protects the root system. Prune any dead or damaged branches to promote healthy growth.
- Be mindful of its spines. Oplopanax Horridus gets its common name "Devil's Club" from its spiky thorns. When handling the plant, wear gloves and exercise caution to avoid injury.
Remember, Devil's Club is a slow-growing plant that can take several years to mature fully. Patience, care, and suitable growing conditions will ultimately lead to a successful Oplopanax Horridus plant.
Place in a dark room with little light, like a dark bedroom or a spot far away from a window or directly in a north-facing window.
Oplopanax Horridus plant requires regular watering, but it is important not to overwater. The soil should be allowed to dry out slightly between waterings. When watering, it is best to water slowly and deeply, allowing the water to penetrate the soil and reach the roots. Avoid watering the foliage, as this can increase the risk of fungal diseases. It is also important to ensure that the plant is not sitting in standing water, as this can lead to root rot. In general, Oplopanax Horridus plant prefers moist, well-drained soil and will benefit from regular fertilization to ensure healthy growth.
To fertilize this plant, you will need a balanced fertilizer that contains equal amounts of nitrogen, phosphorus, and potassium. Apply the fertilizer in the spring when new growth appears and again in the summer. Use a slow-release fertilizer and follow the recommended dosage on the package. Be careful not to over-fertilize as it can be detrimental to the plant. Water the plant thoroughly before and after fertilizing to prevent root burn. Alternatively, you can use organic fertilizers such as compost or manure, which provide a slow-release source of nutrients. Spread a thin layer of organic fertilizer around the base of the plant, taking care not to touch the leaves.
Oplopanax Horridus plant prefers well-draining soils that are rich in organic matter and nutrients. A soil pH that is slightly acidic to neutral is most suitable for this plant. The soil should also retain moisture but not be too wet or waterlogged. A recommended soil mixture would include a combination of loamy soil, sand, and peat moss or compost to improve the soil structure, allow for proper drainage, and maintain adequate water retention. Additionally, adding perlite or vermiculite to the soil can further increase drainage and aeration. It is important to avoid using heavy clay soils and to avoid using fertilizers that are high in nitrogen as they can promote excessive leaf growth at the expense of root development.
To propagate this plant, a stem cutting with healthy foliage should be taken from a mature plant during the spring or summer months. The cutting should be approximately 6 inches in length and have a few leaves attached. The lower leaves should be removed and the stem should be dipped in rooting hormone. The cutting should then be placed in a pot that has been filled with well-draining soil and kept moist but not saturated. The pot should be covered with a plastic bag or dome to create a humid environment. The cutting should be kept in a bright, indirect light location and watered regularly until roots begin to form. Once the cutting has rooted, it can be transplanted into a larger pot or planted in the ground in a suitable location.
