Overview of Anthriscus sylvestris (L.) Hoffmann
Anthriscus sylvestris (L.) Hoffmann, commonly known as cow parsley, wild chervil, or Queen Anne's lace, is a flowering plant species in the family Apiaceae. It is native to Europe, western Asia, and northwestern Africa but is now widely distributed throughout the world and considered a naturalized invasive species in some regions. This biennial plant grows up to 1.5 meters tall with an erect stem and distinctive fine, ferny foliage.
General Appearance of Anthriscus sylvestris
The cow parsley plant has a slender, furrowed stem that is typically green in color when young and turns to reddish-brown as it ages. The leaves are twice-ternate with finely divided, lance-shaped segments that give the plant a delicate, ferny appearance. The plant produces umbels of small, white flowers that typically bloom from May to June. The flowers are followed by small, narrow, flattened fruits that contain brown seeds.
Common Names of Anthriscus sylvestris
The plant is commonly known as cow parsley, wild chervil, or Queen Anne's lace. In some regions, the plant is also called keck, wild beaked parsley, or wild carrot, although the latter name is more commonly used for Daucus carota, another species in the same family. The name "Queen Anne's lace" is believed to have originated from the lacy appearance of the plant's white flower clusters.
Uses of Anthriscus sylvestris
Cow parsley has both culinary and medicinal uses. The young leaves and stems can be eaten raw or cooked and have a slightly sweet, anise-like flavor. The plant was traditionally used in herbal medicine to treat various ailments, including digestive disorders, bronchitis, and urinary tract infections.

Anthriscus sylvestris adapts well to a range of soil types, including sandy, loamy, and clay soils. It prefers well-drained soils with a pH range of 5.5 to 7.5. The plant can grow in soils with low to moderate fertility but may require regular fertilization to promote optimal growth. Additionally, the plant can tolerate dry soil conditions, but it may require supplemental watering during prolonged dry spells.
Cultivation of Anthriscus sylvestris (L.) Hoffmann
Anthriscus sylvestris, also known as cow parsley or wild chervil, is a biennial or short-lived perennial plant that can be grown in a variety of soil types. It prefers a moist and well-drained soil and can be placed in full sun or partial shade.
This plant can be propagated through seeds or by dividing the roots in autumn or spring. It is best to plant the seeds directly into the ground in the autumn to allow for natural stratification over the winter months.
Watering Needs for Anthriscus sylvestris (L.) Hoffmann
Anthriscus sylvestris requires moderate watering. It is important to prevent drought stress by watering it during dry spells. Overwatering should be avoided as it can lead to root rot. The soil should be kept evenly moist to ensure optimal growth.
Fertilization of Anthriscus sylvestris (L.) Hoffmann
Anthriscus sylvestris does not require heavy fertilization. A balanced fertilizer can be applied in the spring to provide sufficient nutrients for the plant's growth. An organic fertilizer such as compost or aged manure can also be used, as it provides long-lasting nutrients for the plant.
Pruning Anthriscus sylvestris (L.) Hoffmann
Pruning is not necessary for Anthriscus sylvestris. However, deadheading the flowers as they fade can help to prolong the blooming period. After the plant has finished flowering, it can be cut back to ground level to promote new growth for the following year. Any yellow or damaged leaves can be removed as needed throughout the growing season.
Propagation of Anthriscus sylvestris (L.) Hoffmann
There are various methods of propagating Anthriscus sylvestris (L.) Hoffmann, a biennial plant commonly known as cow parsley or wild chervil. The propagation methods for cow parsley are straightforward and easy to implement, making it a popular choice in most gardens, farms, and households.
Propagation by Seed
Propagation by seed is the most common method of growing Anthriscus sylvestris. The seeds are readily available in most stores that sell seed varieties for herbaceous plants. It is essential to use fresh, high-quality seeds to ensure high germination rates.
The best time to sow seeds of cow parsley is between April and September, but the optimal period is during spring when the soil temperature is above 10°C. Sowing the seeds is pretty straightforward; make shallow drills, sprinkle the seeds lightly, and cover them with a light layer of soil.
The seeds take around two to four weeks to germinate, depending on the ambient temperature. Once they sprout and develop the first true leaves, thin out to a spacing of 30cm between plants.
Propagation by Cuttings
Although cow parsley does not root easily from cuttings, it is still a viable propagation method. The best time to take cuttings is during the early summer period, between June and July, when the plant is actively growing.
Take cuttings of 6-10cm long from the fresh, healthy, and vigorous shoots of the cow parsley plant. Using sharp, clean scissors or pruning shears, remove the lower leaves from the cuttings, leaving only the top two or three leaves. Dip the cut ends of the cuttings in rooting hormone, and plant them in a mixture of vermiculite and sand. Water the medium and place the pots in a warm, bright area, preferably under a shade. Keep the soil moist but not waterlogged, and the cuttings should develop roots after 2-3 weeks.
Propagation by Division
Propagation by division is another viable method of growing cow parsley. It is best done during the autumn or spring when the plant is dormant. Division involves digging up the mature cow parsley clump and separating it into smaller sections.
Choose a mature Anthriscus sylvestris clump and carefully dig up with a garden spade. Shake off the excess soil and use a clean, sharp knife to separate the clump into smaller sections, ensuring that each section has at least one shoot and well-developed roots. Replant the divided sections to the same depth they were growing before, ensuring the soil is well-compacted around the roots. Water the newly planted cow parsley sections regularly until they establish and start growing.
Disease Management for Anthriscus sylvestris
Anthracnose is a common disease that affects Anthriscus sylvestris. It results in the formation of small, circular, and dark brown spots on leaves and stems, which later cause the leaves to wilt and fall off. To control this disease, it is advisable to remove and destroy the infected plant debris and keep the area clean, dry, and well-ventilated. Avoid overhead irrigation, overcrowding of the plants, and use fungicides as a preventive measure.
Powdery mildew is another common disease that affects Anthriscus sylvestris. It appears as a white powdery growth on the leaves, stems, and flowers of plants. To manage this disease, prune the affected plant parts, provide proper air circulation, and avoid watering from overhead. Using fungicides can help protect the healthy parts and prevent further spread of the disease.
Leaf blight is a disease that causes the leaves of the plant to turn brown and wilt. To manage leaf blight, it is essential to remove and destroy infected plant debris, maintain optimal soil moisture, and improve air circulation around the plant. Fungicides can also be applied to reduce the severity of the disease.
Pest Management for Anthriscus sylvestris
Aphids are small insects that suck the sap from the leaves and stems of Anthriscus sylvestris, causing them to wilt and turn yellow. To manage aphids, release natural predators such as ladybugs and lacewings or use insecticidal soap or neem oil to control their population.
Spider mites are common pests that feed on the leaves of Anthriscus sylvestris, leaving small yellow or white speckles on the leaves. They can be controlled by washing the plant with a strong jet of water, using insecticidal soap, or releasing natural predators like ladybugs or predatory mites.
Caterpillars are the larvae of butterflies and moths that feed on the leaves of the plant, causing significant damage. They can be managed by manually removing the caterpillars, applying Bacillus thuringiensis (Bt) or pyrethrin-based insecticides, or releasing natural predators like birds and parasitic wasps.
Slugs and snails feed on the foliage and stems of Anthriscus sylvestris, leaving large holes and irregularly shaped marks on the leaves. They can be managed by using physical barriers, such as eggshells, diatomaceous earth, or copper tape, or by using snail and slug bait that contains iron phosphate.
