Overview
Tanacetum vulgare L. var. crispum DC. is a perennial plant that is native to Europe and Asia. It is commonly known as curly tansy, or doubletansy.
Appearance
The plant has a bushy habit and can grow up to 1 m tall. The leaves of the plant are finely divided and have a fern-like appearance. They are a bluish-green color, and the edges of each leaflet are slightly curled, giving the plant its characteristic curly appearance. The plant produces yellow button-like flowers, which are clustered together in small, flat-topped clusters.
Uses
Curly tansy has historically been used in traditional medicine to treat a variety of ailments, including digestive problems, respiratory issues, and inflammation. The plant contains a range of biologically active compounds, including flavonoids and sesquiterpene lactones, that are responsible for its medicinal properties. In addition to its medicinal uses, curly tansy is also grown ornamentally in gardens, due to its attractive foliage and flowers.
Light Requirements
Tanacetum vulgare L. var. crispum DC. thrives in full sunlight and requires a minimum of 6 hours of direct sunlight for optimal growth. Insufficient amount of light may result in poor growth and diminished foliage.
Temperature Requirements
This plant is tolerant to a wide range of temperatures. Tanacetum vulgare L. var. crispum DC. can grow within a range of 15°C to 30°C. However, it's important to note that the plant may not perform well during extreme weather conditions.
Soil Requirements
Tanacetum vulgare L. var. crispum DC. prefers well-draining soil that is rich in organic matter. The soil should have a pH range of 6.5 to 7.5 for optimal growth. This plant cannot grow in waterlogged soil and requires good drainage to prevent root rot. It is recommended to use a potting mix that can provide good aeration and drainage to the plant roots.
Cultivation Methods
Tanacetum vulgare L. var. crispum DC. can be easily grown in full sun or partial shade. It prefers a well-draining soil with a neutral or slightly alkaline pH level. The plant can be propagated by either seeds or cuttings.
Watering Needs
This plant requires moderate watering, especially during its growing season. Ensure that the soil is consistently moist but not waterlogged, as this can lead to root rot and other diseases. If planting in a container, make sure to provide proper drainage to prevent water from accumulating at the bottom of the pot.
Fertilization
It is beneficial to add a slow-release fertilizer to the soil during the growing season to improve the plant's overall health and growth. A balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium is suitable for this plant. Be sure to follow the package instructions and do not overfertilize, as this can lead to nutrient burn and other issues.
Pruning
To promote bushier growth, pinch back the stems of the plant regularly during its growing season. This can be done by using your fingertips to gently remove the tips of the stems. Additionally, removing any dead, damaged, or diseased leaves and stems will help keep the plant healthy and looking its best.
Propagation of Tanacetum Vulgare L. Var. Crispum DC.
Tanacetum vulgare L. var. crispum DC., commonly known as tansy, is a perennial herbaceous plant that is known for its attractive and aromatic foliage. The plant has a variety of uses, including as a traditional medicinal herb and as a culinary herb.
Propagation Methods
Tansy can be propagated through seeds, cuttings, or division. Each of these methods has its own advantages and disadvantages, and the choice of method will depend on the grower's preferences and available resources.
Seed Propagation
Seed propagation is an easy and reliable method of propagating tansy. Seeds should be sown in early spring, either outdoors in a prepared seedbed or in pots indoors. Seeds must be sown thinly over the soil and then covered with a very thin layer of soil. Germination can take place in two to three weeks, depending on the temperature and moisture levels.
Cutting Propagation
Cutting propagation involves taking a stem cutting from an existing plant and rooting it to create a new plant. This method is often used when propagating plants that do not produce viable seeds or when the seeds are difficult to obtain. Cuttings should be taken in early summer when the plant is actively growing and then treated with rooting hormone before being planted into a pot or prepared bed. Cuttings should be kept moist and out of direct sunlight until they have formed roots, which can take several weeks.
Division Propagation
Division propagation involves dividing an existing plant into several smaller plants, each with its own root system. This is often done in late summer or early autumn when the plant has finished flowering and is starting to go dormant. The plant should be dug up carefully and then divided into sections, making sure that each section has a healthy root system. These sections can then be planted into pots or directly into the soil.
Disease Management
Tanacetum vulgare L. var. crispum DC. is generally a hardy plant that is not susceptible to many diseases. However, the plant can still be affected by a few diseases that can impact its growth and overall health.
One common disease that affects the plant is powdery mildew. This is a fungal disease that presents as a white powdery coating on the leaves of the plant. It can be managed by improving air circulation around the plant, pruning any affected leaves, and providing adequate water and nutrients to the plant.
Another disease that can affect the plant is gray mold, also known as botrytis blight. This is a fungal disease that can cause the plant to rot and decline. It can be managed by removing any infected tissues from the plant, improving air circulation, and avoiding overwatering the plant.
Pest Management
Tanacetum vulgare L. var. crispum DC. is also vulnerable to a few pests that can damage the plant and reduce its yield. It's important to monitor the plant regularly to catch and manage any pest infestations as early as possible.
One common pest that affects the plant is aphids. These small insects suck the sap from the plant's leaves, causing them to wilt and turn yellow. They can be managed by spraying the plant with a strong jet of water to dislodge them, introducing natural predators like ladybugs and lacewings, or using insecticidal soap.
Another pest that can affect the plant is spider mites. These tiny pests feed on the underside of the plant's leaves, causing them to yellow and drop. They can be managed by spraying the plant with a strong jet of water, introducing natural predators like phytoseiid mites and ladybugs, or using insecticidal soap.
Overall, the key to managing diseases and pests in Tanacetum vulgare L. var. crispum DC. is to monitor the plant regularly and take quick action whenever any issues are detected. By following good gardening practices and using appropriate management techniques, you can ensure that your plant remains healthy and productive.
