Origin
Acetosa pratensis P. Mill. ssp. alpestris (Jacq.) A. Löve, also known as Alpine sorrel, is a species of perennial flowering plant in the genus Rumex, family Polygonaceae. It is native to Europe, specifically found in alpine regions of Austria, France, Germany, Italy, and Switzerland.
Common Names
The plant is commonly known as Alpine sorrel, French sorrel, or Mountain sorrel.
Uses
The plant has historically been used as a medicinal herb, primarily for treating digestive disorders such as diarrhea and constipation. It has also been used for its diuretic properties to treat urinary tract infections. Alpine sorrel leaves are edible and are often used in salads or as a cooked green. The plant contains oxalic acid, which gives it a sour taste and contributes to its use as a culinary herb.
General Appearance
Alpine sorrel is a perennial herb that typically grows to be 15-50 cm tall. Its leaves are alternate and roughly triangular, with a sour taste due to their high oxalic acid content. The leaves have a distinct arrowhead shape and are hairless. The flowers are small and greenish-red in color, arranged in loose clusters on long stems. The stems are typically reddish in color and grow from a thick, woody rootstock. Alpine sorrel prefers moist, well-drained soils in alpine meadows and rocky slopes.
Light Requirements
The Acetosa pratensis P. Mill. ssp. alpestris (Jacq.) A. Löve plant thrives in areas where there is an ample amount of light. Direct sunlight is ideal, although it still grows well in partially shaded areas. The species is intolerant to low light conditions, so avoiding dark places is crucial to ensure maximum growth.
Temperature Requirements
The Acetosa pratensis P. Mill. ssp. alpestris (Jacq.) A. Löve plant grows best in moderate temperatures, which is between 12 and 25 degrees Celsius. The plant can tolerate temperatures as low as -30 degrees Celsius, though lower temperatures can significantly impact its growth rate. Prolonged exposure to high temperatures above 30 degrees Celsius can cause the plant to wilt and halt growth altogether.
Soil Requirements
The plant requires well-draining and aerated soil, rich in organic nutrients. It can grow in various types of soil, including clay, loam, and sand. The soil should have a pH range of 4.5 to 8.0 and be slightly acidic to alkaline. Also, the soil should be moderately moist, avoiding waterlogged conditions that can cause root rot. Adding compost and manure improves soil nutrient levels and texture.
Cultivation of Acetosa pratensis P. Mill. ssp. alpestris (Jacq.) A. Löve
Acetosa pratensis P. Mill. ssp. alpestris (Jacq.) A. Löve, commonly known as alpine sorrel, is a hardy perennial plant that can be easily grown in a favorable environment. The plant prefers moist, well-draining soil and grows best in full sunlight.
It is recommended to sow the seeds of alpine sorrel in early spring and make sure that the soil temperature is above 10°C. The seeds should be sown in furrows, 1/4 inch deep and spaced 12 inches apart. After about two weeks, the seedlings will emerge, and they can be thinned out to a spacing of 6-8 inches apart.
Watering needs of Acetosa pratensis P. Mill. ssp. alpestris (Jacq.) A. Löve
Alpine sorrel requires regular watering to grow correctly. The plant prefers moist soil, which should be kept evenly moist during the growing season. Adequate moisture helps the plant to establish roots, promotes growth and ensures the leaves remain succulent and tender.
It is recommended to water the plant once every one or two weeks, depending on the weather conditions. In hot and dry weather, it is necessary to water the plant more frequently, while minimal watering is required during the rainy season.
Fertilization of Acetosa pratensis P. Mill. ssp. alpestris (Jacq.) A. Löve
Alpine sorrel does not require any fertilizers to grow, but applying a nitrogen-rich fertilizer can increase the plant's growth and yield. It is recommended to apply an all-purpose fertilizer during the active growing season to provide the essential nutrients required by the plant.
The fertilizer should be applied once every two months at a rate of 1/4 cup per plant. Overfertilizing should be avoided as it can make the plant more susceptible to diseases and pests.
Pruning of Acetosa pratensis P. Mill. ssp. alpestris (Jacq.) A. Löve
Alpine sorrel does not require any specific pruning techniques, but harvesting the leaves regularly encourages the growth of new leaves and promotes bushier growth. The leaves should be picked carefully by snapping them off at the base of the stem.
The plant will produce new leaves throughout the growing season, and it is recommended to harvest the leaves before the flowers begin to form. This ensures that the leaves are tender and have the best flavor.
Propagating Acetosa pratensis P. Mill. ssp. alpestris (Jacq.) A. Löve

Propagation Methods for Acetosa pratensis P. Mill. ssp. alpestris (Jacq.) A. Löve
The plant can be propagated in different ways including:
1. Division
Propagation through division is the easiest and most common method of propagating Acetosa pratensis P. Mill. ssp. alpestris (Jacq.) A. Löve. This is done by dividing clumps of the plant in spring or autumn, ensuring each division has several strong roots and healthy-looking shoots. The divisions should be replanted immediately and kept well-watered until they are fully established.
2. Seeds
Seeds can also be used to propagate Acetosa pratensis P. Mill. ssp. alpestris (Jacq.) A. Löve. However, it is important to note that the plant rarely sets seed, and even when it does, it has a low germination rate. The seeds should be sown in late summer in a well-prepared bed, and covered lightly with soil. They should be kept moist and well-watered until they germinate. Once the seedlings are large enough, they can be transplanted to their final position.
3. Cuttings
Cuttings can also be used to propagate Acetosa pratensis P. Mill. ssp. alpestris (Jacq.) A. Löve. This method is best suited for more experienced gardeners. Cuttings should be taken in spring or summer, and should be about 10 cm long, with a few healthy leaves. Cuttings should be planted in a well-prepared bed and kept moist until they are fully rooted.
Propagation of Acetosa pratensis P. Mill. ssp. alpestris (Jacq.) A. Löve requires patience and care. The plant is tough and hardy, and can grow in a variety of soil types, making it an ideal choice for inexperienced gardeners.
Disease and Pest Management for Acetosa pratensis P. Mill. ssp. alpestris (Jacq.) A. Löve
Acetosa pratensis P. Mill. ssp. alpestris (Jacq.) A. Löve is generally a hardy plant that is resilient to many diseases and pests. However, it can still be vulnerable to certain conditions that can affect its overall health and growth. To maintain the plant’s vigor and beauty, proper disease and pest management strategies should be employed.
Common Diseases
One of the most common diseases that can affect Acetosa pratensis P. Mill. ssp. alpestris (Jacq.) A. Löve is powdery mildew. This fungal disease appears as a white powdery substance on the leaves, stems, and flowers of the plant. To manage powdery mildew, the use of fungicides and ensuring adequate air circulation can be helpful. It is also important to avoid wetting the leaves of the plant while watering as excess moisture can contribute to the development of the disease.
Another disease that can affect Acetosa pratensis P. Mill. ssp. alpestris (Jacq.) A. Löve is root rot. This condition is caused by overwatering and poor drainage, which can lead to the roots of the plant being waterlogged and deprived of oxygen. To manage root rot, it is crucial to ensure that the plant is not overwatered and that the soil is well-drained. Fungicides can also be used to manage the disease.
Common Pests
A common pest that can affect Acetosa pratensis P. Mill. ssp. alpestris (Jacq.) A. Löve is the aphid. These small insects can cause damage to the plant by sucking sap from the leaves, resulting in yellowing and curling of the foliage. To manage aphids, insecticidal soaps and oils can be applied to the plant. Additionally, natural predators of aphids such as ladybugs can be introduced to the environment to control their population.
Another pest that can affect Acetosa pratensis P. Mill. ssp. alpestris (Jacq.) A. Löve is the spider mite. These tiny pests can cause leaf discoloration and distortion and can be difficult to manage due to their small size. To manage spider mites, the plant can be sprayed with insecticidal soaps or horticultural oils. Additionally, increasing the humidity around the plant can be helpful as spider mites thrive in dry conditions.
Overall, effective disease and pest management for Acetosa pratensis P. Mill. ssp. alpestris (Jacq.) A. Löve involves early detection of problems, proper cultural practices, and the use of appropriate management strategies. With proper care, this plant can thrive in a healthy and beautiful manner.
