Besides its scientific name, Peucedanum platycarpum is also known by other common names such as Bitterwortel, Olyfwortel, Wilde Pietersielie, and Wilde Seldery.
Appearance
Peucedanum platycarpum grows up to 1m tall and has a fibrous root system. The plant has divided leaves with oblong segments that are finely toothed. The flowers are small and yellow-green, clustered in umbels, and bloom from August to March. The fruits are 2-3 cm long, oval-shaped and have a light brown color.

The plant has antibacterial and anti-inflammatory properties and may also be used to alleviate pain and fever. In addition, the seeds are used to make a spice that has a similar taste to anise or fennel.
Light Requirements
Peucedanum platycarpum requires full sun to partial shade for optimal growth. It can tolerate some shade, but too much shade can result in poor growth and weak stems.
Temperature Requirements
Peucedanum platycarpum prefers moderate to cool temperatures. It is found in areas where the average annual temperature is between 12°C and 22°C. It can tolerate some frost, but temperatures below -5°C can damage or kill the plant.
Soil Requirements
Peucedanum platycarpum prefers well-drained soils that are rich in organic matter. It can grow in a wide range of soil types, including loamy soils, clay soils, and sandy soils. The soil pH should be neutral to slightly acidic (pH 6.0 to 7.0).
Cultivation methods
Peucedanum platycarpum E.Mey. ex Sond. prefers well-drained soils with a pH between 6.0 and 7.0. This plant grows best in full sun but can tolerate partial shade. It is recommended to start the growing process indoors and then transplant the seedlings outdoors once they are strong enough to survive the harsh conditions.
Watering needs
Peucedanum platycarpum E.Mey. ex Sond. requires moderate watering during the growing season. The soil should be kept evenly moist but not soggy. Overwatering can cause the roots to rot, while underwatering can lead to stunted growth. It's best to water the plant in the morning to allow for proper drying throughout the day.
Fertilization
Peucedanum platycarpum E.Mey. ex Sond. can benefit from fertilizer application in the form of compost, organic matter, or slow-release fertilizers. This should be done once a month during the growing season. Avoid applying fertilizer too close to the plant's stem, as this can burn the roots and damage the plant.
Pruning
Peucedanum platycarpum E.Mey. ex Sond. doesn't require heavy pruning, but it's essential to remove any dead or diseased leaves and stems. Additionally, cutting back the plant after it has flowered can promote bushier growth. This can be achieved by cutting back the top third of the stems. However, make sure not to cut back more than one-third of the plant at any given time.
Propagation of Peucedanum platycarpum E.Mey. ex Sond.
There are different methods of propagating Peucedanum platycarpum E.Mey. ex Sond. depending on the availability of resources, time, and the preference of the gardener. The plant is commonly propagated by seeds, cuttings, or division of mature plants.
Propagation by Seeds
Peucedanum platycarpum E.Mey. ex Sond. seeds can be sown directly on the soil in spring or fall. The seeds should be lightly covered with soil, and the soil should be kept moist until germination occurs, which usually takes around two weeks. It is important to keep the soil moderately moist during the first year of growth.
Propagation by Cuttings
Propagation by cuttings is an alternative method to seeds. Stem cuttings are taken from mature plants and planted into a rooting medium. A mix of peat, perlite, and vermiculite is ideal for rooting cuttings. The cuttings should be kept in a warm, humid environment, preferably with high humidity. Roots should start developing after a few weeks, and the young plants should be transplanted into individual pots or directly on the soil when they are well-rooted.
Propagation by Division
Division is another method of propagating Peucedanum platycarpum E.Mey. ex Sond. This can be done by separating the root ball of a mature plant into two or more sections and replanting them. This method is best done in the fall when the plant is dormant. After division, the plants should be regularly watered until they are well-established.
Disease and Pest Management for Peucedanum Platycarpum
Peucedanum platycarpum, commonly known as the broad-fruited hog fennel, is a herbaceous plant that belongs to the family Apiaceae. Like many other plants, Peucedanum platycarpum is susceptible to various diseases and pests, which can stunt its growth and lead to significant yield losses. Here are some common diseases and pests that might affect the plant as well as suggestions on how to manage them:
Common Diseases
Crown Rot
Crown rot is a fungal disease that affects the crown or base of the plant, causing it to wilt and eventually die. It is often caused by soil-borne fungi such as Fusarium spp. and Phytophthora spp. The disease can be prevented by avoiding planting Peucedanum platycarpum in poorly-drained soils and by maintaining proper soil sanitation. Fungicides can also be used to treat the disease.
Powdery Mildew
Powdery mildew is a fungal disease that affects a wide range of plants, including Peucedanum platycarpum. It is characterized by the appearance of a white or gray powdery coating on the leaves, stems, and flowers of the plant. The disease can be controlled by maintaining proper air circulation around the plant as well as keeping the foliage dry. Fungicides can also be used to treat the disease.
Leaf Spot
Leaf spot is a fungal disease that affects the leaves of the plant. It is characterized by the appearance of small, circular, brown or black spots on the leaves. The disease can be prevented by avoiding overhead watering, removing infected leaves from the plant, and maintaining proper soil sanitation. Fungicides can also be used to treat the disease.
Common Pests
Aphids
Aphids are tiny insects that feed on the sap of the plant, causing the leaves to yellow and curl. They can also transmit viruses to the plant. The pests can be controlled by spraying the plant with a strong jet of water to dislodge them or by applying insecticidal soap or neem oil.
Spider Mites
Spider mites are tiny pests that feed on the underside of the leaves, causing them to turn yellow and eventually fall off. They can also cause webbing on the leaves. The pests can be controlled by applying insecticidal soap or neem oil to the plant.
Slugs and Snails
Slugs and snails are common pests that can cause significant damage to Peucedanum platycarpum. They feed on the leaves and stems of the plant, leaving behind large holes and ragged edges. The pests can be controlled by removing them by hand or by applying slug and snail bait around the base of the plant.
