Draba alpina L. typically grows up to 5-20 centimeters in height, forming compact mats and cushions. It has lanceolate leaves that grow in basal rosettes, and small, white flowers that bloom from April to September. The plant produces numerous seeds, which are dispersed by wind or water.
Common Names of Plant Draba alpina L.
Aside from alpine whitlowgrass, Draba alpina L. is also known by other common names such as mountain whitlowgrass, alpine whitlowwort, and alpine draba.
Uses of Plant Draba alpina L.
Draba alpina L. has traditionally been used in herbal medicine to treat various ailments such as respiratory problems, indigestion, and skin infections. The plant is also edible, with the young leaves and flowers being added to salads or cooked as a vegetable. Additionally, the plant is valued as an ornamental and is often grown in rock gardens or alpine troughs.
Light Requirements
Draba alpina L. prefers full sun to partial shade. This species grows best in areas with high levels of sunlight, but it can tolerate some shade. When grown in partial shade, the plant may produce fewer flowers and have a less compact growth habit.
Temperature Requirements
The growth of Draba alpina L. is influenced by temperature. It is an alpine plant with a preference for cool temperatures and can grow well in areas with a continental climate. This species is adapted to cold conditions and can survive, thrive, and produce flowers in temperatures as low as -20°C. However, it cannot withstand extreme heat, and temperatures above 30°C can adversely affect its growth and development.
Soil Requirements
Draba alpina L. can grow well in a variety of well-drained soils, including sandy, loamy, or gravelly soils. This species prefers moist soils, but it can withstand periods of drought. It is adapted to acidic soils with a pH range of 4.5 to 6.5 and can grow in soil with low nutrient content. It is recommended to mix organic matter with the soil and ensure that it has excellent drainage as the plant is susceptible to rot in damp soil.
Cultivation methods for Draba alpina L.
Draba alpina L. is an alpine plant that prefers a cold and moist environment. It can be grown in various soil types, but it does best in well-drained soil that is rich in organic matter. It is best to plant Draba alpina L. in early spring, as soon as the ground thaws and can be worked.
The plant can be propagated through seed or by dividing mature plants. For seed propagation, sow the seeds in a container in late winter or early spring, and then transplant them outside in the summer. For division, lift the mature plant clump in early spring and divide it into smaller clumps, replanting them in pots or directly outside.
Watering needs for Draba alpina L.
Draba alpina L. needs regular watering during the growing season. Keep the soil moist, but not waterlogged. Water the plant when the top few inches of soil feel dry to the touch. It is best to water in the early morning or late afternoon, avoiding midday heat when the sun can cause water droplets to scorch the leaves.
Fertilization of Draba alpina L.
Draba alpina L. does not need heavy fertilization. In fact, it will do just fine without any fertilizer at all. However, if you want to give it a little boost, use a granular slow-release fertilizer that is low in nitrogen once a month during the growing season. Avoid fertilizing the plant in winter.
Pruning for Draba alpina L.
Draba alpina L. does not need much pruning. However, it is best to remove any dead or diseased foliage at any time of the year. After blooming, cut back the plant to encourage more compact growth and better flowering the following year.
Propagation of Draba alpina L.
Draba alpina L. is generally propagated through seeds, but it can also be propagated through division or cuttings.
Propagation by Seeds
The ideal time to sow Draba alpina L. seeds is in the spring or autumn. The seeds should be sown in well-drained soil, and it should be kept moisture throughout the germination process. The germination of Draba alpina L. seeds takes 4 to 6 weeks. Before sowing, the seeds can be stratified in a refrigerator for 2 to 4 weeks to break dormancy. The seedlings should be kept in a slightly shaded area until they are ready to be transferred to their permanent location.
Propagation by Division
Draba alpina L. can be propagated through division in late summer or early autumn. When dividing, the plant must be lifted from the soil with care, and the root crown should be divided using a sterile knife or pruning shears. Each new division should have both root and shoot systems. The new division should be replanted in a suitable location and kept moist until established.
Propagation by Cuttings
Draba alpina L. can also be propagated through cuttings. The cuttings should be taken during the summer months when the plant is in active growth. The cuttings should be around 3 to 4 inches long, and the lower leaves should be removed. The cuttings should be dipped in rooting hormone powder and planted in a well-draining soil mix. The cuttings should be kept moist and in a shaded area for several weeks. Once the cuttings develop roots and establish, they can be transplanted to their permanent location.
Disease and Pest Management for Draba alpina L.
Draba alpina L. is a species of plant that is commonly found in the alpine regions of Europe and Asia. Like other plants, it is susceptible to diseases and pests that can affect its growth and productivity. Here, we discuss some common diseases and pests that might affect Draba alpina L. and suggest ways to manage them effectively.
Common Diseases
Below are some common diseases that might affect Draba alpina L.:
Fungal Diseases
Fungal diseases such as powdery mildew, leaf spot, and rust can affect Draba alpina L. Powdery mildew appears as a white, powdery coating on the leaves, while leaf spot appears as circular or irregular spots. Rust usually appears as small, reddish-brown pustules on the underside of the leaves.
To manage fungal diseases, you can apply a fungicide to the affected plants. Remove and destroy any infected plant parts to prevent the spread of the disease. Ensure you are using a fungicide that is safe for use on Draba alpina L. and follow the manufacturer's instructions for application.
Viral Diseases
Viral diseases such as cucumber mosaic virus and tomato spotted wilt virus can also affect Draba alpina L. Symptoms of viral diseases include distorted growth, yellowing, and stunted plant growth.
There is no cure for viral diseases, and infected plants should be removed and destroyed to prevent the spread of the disease. To prevent viral diseases, avoid planting Draba alpina L. near infected plants and ensure that seeds and cuttings are virus-free.
Common Pests
Below are some common pests that might affect Draba alpina L.:
Aphids
Aphids can suck sap from the leaves and stems of Draba alpina L., causing stunted growth and distorted leaves. They can also transmit viral diseases.
To manage aphids, you can spray the affected plants with insecticidal soap or neem oil. Introduce natural predators, such as ladybirds, to the garden to control aphid populations.
Slugs and Snails
Slugs and snails can feed on the leaves of Draba alpina L., resulting in holes and damage to the plant. They are most active at night and in damp conditions.
To manage slugs and snails, you can use physical barriers, such as copper tape, around the base of the plant to prevent them from reaching the leaves. Use slug pellets, if necessary, but avoid using them near waterways as they can be harmful to wildlife.
By following these guidelines, you can help to keep your Draba alpina L. healthy and productive, despite the challenges posed by pests and diseases.
