Datura tatula L. is a species of plant from the nightshade family of Solanaceae. This plant is native to South America, but it can now be found in different parts of the world, including Africa, Asia, and Europe.
Common names
Datura tatula L. goes by different common names, depending on the country and region. In English speaking countries, it is commonly known as Purple Thorn Apple, Devil's Trumpet, Jimsonweed, Moonflower, and Angel's Trumpet. In other parts of the world, it is referred to as Trompeta del Diablo, Yerba del Diablo, Tatula, Tolguacha, and Stramonio.
Uses
Datura tatula L. has been used in traditional medicine for centuries, although it is known to be toxic and have potentially harmful side effects. Its leaves, seeds, and flowers contain tropane alkaloids, which have psychoactive properties and can cause hallucinations, confusion, and memory loss. However, when used with caution, Datura tatula L. has medicinal uses.
The plant has been used traditionally as an anti-inflammatory agent, analgesic, and sedative. The seeds were once used to treat asthma and other respiratory conditions. The extract of the plant's leaves and flowers was used to treat wounds, inflammation, and as an anesthetic.
General appearance
Datura tatula L. is a herbaceous annual plant that can grow up to 60 cm in height. It has large, somewhat hairy, dark green leaves that are ovate and irregularly shaped, measuring 10-15 cm long and 5-13 cm wide. Its trumpet-shaped flowers bloom in summer and are usually purple or violet, measuring 7-10 cm long and 5-8 cm wide. Its seed pods are round and spiky and contain black, kidney-shaped seeds that are 3-4 mm in diameter.
The plant is highly adaptable and can grow in various environments, including disturbed areas, roadsides, and gardens. It can thrive in sandy and loamy soils and prefers a warm and sunny climate.
Light Requirements
Datura tatula L. thrives in full sunlight, therefore it is necessary to place the plant in an area that receives at least 6 hours of direct sunlight each day. It is not likely to grow to its full potential if cultivated in an area that is shaded throughout the day.
Temperature Requirements
The recommended temperature range for growing Datura tatula L. is between 20 to 30 degrees Celsius. At temperatures below 20°C, the plant growth may be delayed, and the plant may become susceptible to diseases. Similarly, at temperatures above 30°C, the plant's growth may become stunted, and the flower production may decline.
Soil Requirements
The soil type plays a vital role in the growth of Datura tatula L. The ideal soil for the plant is well-drained soil rich in organic matter. The soil must have a pH range of 6.5 – 7.5. A pH value that is lower than 6.5 would make the soil acidic to the extent where it may not be able to support plant life, while a pH value higher than 7.5 could make the soil alkaline, leading to mineral deficiencies in the plant.
Cultivation
Datura tatula L. is a robust and adaptable plant species that is best grown in an outdoor garden. It thrives in warm and sunny conditions and can tolerate a wide range of soil types, but prefers a well-draining soil that is rich in organic matter.
The plant should be sowed in a spot where it can receive at least 6 hours of direct sunlight per day. The seeds should be sowed directly into the ground in early spring after the last frost or started indoors in pots 4-6 weeks before the last expected frost.
Datura tatula L. develops a taproot quickly, which is why it is not advantageous to transplant it. It is best to start the seedlings in individual biodegradable pots, planters, or seedling trays, which limit root disturbance upon transplanting.
Watering Needs
Datura tatula L. plants require deep watering once a week, especially during prolonged dry periods. Overwatering the plant may cause the roots to rot and ultimately cause the death of the plant. Ensure that the soil is moist up to an inch below the surface.
Additionally, Datura tatula L. plants benefit from a rain gauge, which measure precipitation levels, allowing you to adjust watering amount when necessary. Water in the early morning and avoid watering plant leaves as this promotes fungal growth.
Fertilization
Datura tatula L. plants require regular fertilization during the growing season. Use a balanced liquid fertilizer containing all 3 essential nutrients: nitrogen, phosphorus and potassium.
It is advisable to fertilize the plant every two weeks for continuous growth during the growing season. It's best to avoid applying fertilizers too close to the stem, since this can burn or damage the plant.
Pruning
Pruning is an important aspect of Datura tatula L. plant care. It enhances shape, promotes flowering, and prevents the plant from overgrowing its designated space.
The best time to prune Datura tatula L. is in late winter or early spring. You can remove up to a quarter of the plant's height, cutting back to where the stem begins to branch. Thinning out old or damaged wood and removing dead flowers can also keep the plant flourishing.
Also, it is a good practice to wear protective gloves when handling Datura tatula L. plant parts, since they contain toxic chemicals that can be dangerous when ingested or inhaled.
Propagation of Datura tatula L.
Datura tatula L. is commonly propagated through seeds. However, stem cuttings can also be used as a propagation method.
Propagation through Seeds
The seeds of Datura tatula L. are viable for up to four years. They should be collected when the capsules have dried and turned brown. The seeds should be cleaned and stored in a cool and dry place until planting time.
Seeds can be sown directly in the garden bed or in containers. It is best to sow the seeds in the spring after the last frost. The seeds should be planted at a depth of ¼ inch and spaced at least 12 inches apart. Regular watering is necessary until the seedlings are established.
Once the seedlings have grown to a height of 6 inches, they can be transplanted to their permanent location in the garden. It is best to plant them in well-drained soil in a location that receives full sun to partial shade.
Propagation through Stem Cuttings
Stem cuttings can be taken from a mature Datura tatula L. plant. The cuttings should be at least 6 inches in length and should have at least two nodes on them. The cuttings should be taken from the plant in the spring or summer.
The cuttings should be dipped in rooting hormone and placed in a container filled with moist soil. It is important to keep the soil moist and to provide the cutting with partial shade until it has rooted.
Once the cutting has rooted, it can be transplanted into a larger container or directly in the garden bed. It is important to ensure that the soil is well-drained and that the plant receives full sun to partial shade.
