Common Names
The plant is commonly known as pricklyburr, thorn apple, jimson weed, or devil's snare.
Uses
The pricklyburr has been used in traditional medicine to treat a variety of ailments like asthma, rheumatism, and fever. However, these uses are not recommended as the plant is highly toxic and can cause hallucinations, delirium, and even death when ingested. The plant's seeds and leaves contain tropane alkaloids, which are poisonous and cause anticholinergic symptoms.
The pricklyburr is also known for its psychoactive effects and has been used for recreational purposes. However, it is important to note that the plant is highly unpredictable, and the effects can be fatal.
General Appearance

The plant's flowers are trumpet-shaped and can be white or pale pink in color. The pricklyburr produces a capsule-like fruit covered with sharp, spiny burrs that resemble a porcupine's quills.
The pricklyburr is commonly found in open areas, disturbed sites, and along roadsides. The plant thrives in sandy or loamy soil and can tolerate dry conditions. It is often considered a weed due to its aggressive growth and ability to spread quickly.
Growth Conditions for Datura kymatocarpa Barclay
Light: Datura kymatocarpa Barclay generally thrives in full sun, although they can also grow under partial shade. However, in order to sustain healthy growth and flower development, it is recommended to provide at least 6 hours of direct sunlight daily.
Temperature: The ideal temperature for Datura kymatocarpa Barclay to grow is between 20°C to 27°C. They can tolerate a minimum temperature of 16°C but cannot survive frost and extremely low temperatures. In locations with hot summers, it is recommended to provide some shade during the hottest hours of the day to prevent dehydration.
Soil: Datura kymatocarpa Barclay thrives in well-draining soils that are rich in organic matter. They can grow in a wide range of soil pH levels, from acidic to slightly alkaline. While they are tolerant to a variety of soil types, it’s important to ensure that the soil is moist but not waterlogged. Amend heavy or compacted soils with sand or compost to increase drainage and improve soil structure.
Water: Young Datura kymatocarpa Barclay plants require regular watering until they become established. Once established, the plants are quite tolerant to drought and can go for extended periods without water. Water deeply but infrequently to avoid waterlogging the soil or increasing the risk of fungal diseases. Always ensure that the soil is dry before watering.
Fertilizer: Datura kymatocarpa Barclay does not require much fertilizer, if any. An application of a balanced fertilizer once or twice a year (during the growing season) may be beneficial but it’s important not to over-fertilize as it may lead to excessive growth and reduced flowering.
By paying attention to these growth conditions, you can ensure that your Datura kymatocarpa Barclay plant grows healthy and strong.
Cultivation methods for Datura kymatocarpa Barclay
Datura kymatocarpa Barclay, commonly known as the spiny thorn-apple, is a shrub that grows naturally in tropical regions. It is easy to cultivate and can be grown in most regions except for areas with extreme cold temperatures. When planting Datura kymatocarpa Barclay, it is advisable to plant it in well-drained soil and in a location that receives full sunlight.
Propagation of Datura kymatocarpa Barclay can be through seeds, cuttings, or transplanting. Seeds are sown in warmer climates in early spring, while cuttings can be taken during the summer and planted in a suitable potting mix. Transplanting is done during early spring or late fall, and it requires the young plant to be well-established before winter.
Watering needs
Datura kymatocarpa Barclay requires regular watering during its growing season, which is spring and summer. The plant prefers moist soil, but it is important not to overwater it as this can lead to root rot. It is advisable to water the plant deeply once a week rather than providing regular shallow watering. During the colder months, the plant requires less watering.
Fertilization
It is advisable to fertilize Datura kymatocarpa Barclay during its growing season to promote healthy growth and blooming. Use a balanced fertilizer with higher levels of phosphorus to promote blooming. Fertilize the plant every four weeks during the growing season and, as always, follow manufacturer's instructions for the appropriate amount and method of application.
Pruning
Pruning Datura kymatocarpa Barclay is essential to promote bushy growth and a more abundant blooming. It is best to prune the plant during the late winter or early spring before new growth starts. It is essential to use clean and sharp pruning shears to avoid damaging the plant's woody stems. Prune out any dead or diseased parts of the plant, thin out any crowded areas to allow for better air circulation, and reduce the size of the plant if it has outgrown its space.
Propagation of Datura kymatocarpa Barclay
Datura kymatocarpa Barclay, commonly known as Kymatocarpa, is a perennial shrub that belongs to Solanaceae family. The plant is native to Bolivia and is widely grown in other countries for its ornamental and medicinal values. Propagation of this plant can be done through various methods such as seeds, stem cuttings, and layering.
Propagation through Seeds
Seeds are the most commonly used method for propagating Datura kymatocarpa Barclay. Seeds can be collected from dried fruits as soon as they turn brown. The seeds should be soaked in water for 24 hours before sowing. The planting medium should contain equal parts of sand and peat moss. Sow the seeds at a depth of 1/4 inch, and keep the soil moist until germination, which usually takes 2-3 weeks. Once the seedlings have grown to a suitable size, transplant them to the desired location.
Propagation through Stem Cuttings
Stem cuttings can be used to propagate Datura kymatocarpa Barclay. Select a healthy stem and cut a 6-inch piece from it. Remove the leaves from the bottom half of the stem and make a diagonal cut at the bottom. Dip the cut end in rooting hormone and plant it in a pot containing a well-draining planting medium. Keep the soil moist and place the pot in a warm, bright location. It usually takes 4-6 weeks for the cutting to root. After rooting, transplant the cutting to the desired location.
Propagation through Layering
Layering is another method of propagating Datura kymatocarpa Barclay. Select a healthy branch that is close to the ground and make a small wound in the middle of the branch. Place soil over the wound and cover it with a plastic wrap. Keep the soil moist until the roots have formed, which usually takes 4-6 weeks. Once the roots have formed, cut the branch from the mother plant and transplant it to the desired location.
Disease and Pest Management for Datura kymatocarpa Barclay
Datura kymatocarpa Barclay, also known as the sacred datura or thorn apple, is a beautiful yet toxic plant that can be affected by several diseases and pests. Here are some common problems that might arise and ways to manage them:
Diseases
Fungal diseases: Datura kymatocarpa Barclay is susceptible to several fungal diseases, such as leaf spot, powdery mildew, and root rot. These diseases can cause leaf deformations, yellowing, and premature leaf drop. To manage fungal diseases, it is important to avoid overhead watering and to keep the soil well-drained. Additionally, removing infected plant debris and treating the plant with a fungicide can be effective solutions.
Bacterial diseases: Datura kymatocarpa Barclay can also be affected by bacterial diseases, such as bacterial leaf spot and canker. These diseases can cause dark spots on the leaves, stem cankers, and dieback. To prevent these diseases, it is important to avoid injuring the plant and to maintain good sanitation practices. Treating the plant with a copper-based fungicide can also be effective.
Pests
Caterpillars: Datura kymatocarpa Barclay can be attacked by caterpillars, which can cause severe defoliation. To manage them, it is important to inspect the plant regularly and to pick off any caterpillars that are spotted. Additionally, introducing natural predators, such as birds or beneficial insects like lacewings and ladybugs, can keep caterpillar populations in check.
Aphids: Another common pest that can attack Datura kymatocarpa Barclay is aphids. These small insects suck the sap from the leaves and can cause curling, yellowing, and stunted growth. To manage them, it is important to wash the plant with a strong spray of water or to treat it with insecticidal soap or neem oil.
By following these disease and pest management tips, you can help your Datura kymatocarpa Barclay stay healthy and beautiful.
