Overview of Cleome gossweileri Exell
Cleome gossweileri Exell is a species of flowering plant in the family Capparaceae, which is native to Africa. It is commonly known as Gossweiler's spiderflower.
Appearance
Cleome gossweileri Exell is an erect annual herb that grows up to 30 cm in height. It has simple, alternate leaves that are palmately compound with three or five leaflets and are up to 11 cm long. The plant produces delicate pink or lavender flowers that form elongated inflorescences with a length of up to 20 cm. The flowers bloom in summer and are followed by long, narrow seed pods up to 9 cm in length.
Uses
Cleome gossweileri Exell has a few uses. It is often grown as an ornamental plant and is valued for its delicate flowers and striking appearance. It is also used for medicinal purposes in some African cultures. The leaves and seeds have been used to treat ailments such as fever and skin diseases. Additionally, the plant is used to make a natural yellow dye known as "kichwa."
Cultivation
Cleome gossweileri Exell is a hardy plant that prefers full sun and well-drained soil. It is easy to grow from seed and can be started indoors or directly sown outside. The plant is drought-tolerant once established and does best in hot, arid climates. It can be grown as an annual in cooler regions or as a perennial in warm climates. The seeds are often collected and used for propagation and can be stored for several years.
Light requirements
Cleome gossweileri Exell thrives in areas with plenty of sunlight. It requires exposure to at least 6 hours of direct sunlight per day to grow optimally. It is also tolerant of partial shade but may not achieve its full potential in such conditions.
Temperature requirements
The plant is well adapted to grow in warm temperatures ranging from 18 to 34 degrees Celsius. It is susceptible to frost and extreme cold, and temperatures below 10 degrees Celsius could kill the plant. Therefore, it is advisable to plant the Cleome gossweileri Exell during the warmer months.
Soil requirements
The best soil for growing the Cleome gossweileri Exell is well-draining, fertile, and rich in organic matter. It thrives on soils with a pH range of 6.0 to 7.5, which are slightly acidic to neutral. The soil should also be moist, but not waterlogged. Adding organic matter such as compost or well-rotted manure to the soil before planting can help improve soil fertility and drainage.
Cultivation Methods
Cleome gossweileri Exell, commonly known as spider flower, is a tropical plant species that thrives in well-drained soils with adequate organic matter. It prefers sandy or loamy soils with a slightly acidic to neutral pH of 6-7.5. The plant requires full sun exposure but can also tolerate partial shade.
The best time to plant spider flowers is in the spring after the last frost. Plant the seeds 1/4 inch deep and 2-3 inches apart, then lightly water the soil to keep it moist. Germination usually takes between 7-21 days. Thin the seedlings to a spacing of 12-18 inches to allow proper air circulation and reduce the risk of fungal disease.
Watering Needs
Spider flowers require consistent moisture levels in the soil to thrive, but it is essential not to overwater them. Water the plant deeply once a week, giving it enough water to soak the soil to a depth of 6-8 inches. In hot and dry summers, water the plants more often, but do not allow the soil to become waterlogged. Overwatering can lead to root rot, yellowing of leaves, and stunted growth.
Fertilization
Cleome gossweileri Exell requires moderate fertilization throughout the growing season. Apply a balanced fertilizer, such as a 10-10-10 or 12-12-12, every 4-6 weeks during the growing season. Ensure that the fertilizer is applied evenly around the base of the plant and not on the plant's foliage. Over-fertilizing can lead to excessive vegetative growth and can reduce flowering.
Pruning
Pruning of spider flowers is not mandatory, but it can result in bushier growth and increased flowering. Pinching the top one-third of the plant's stem can promote branching. Deadheading, that is, the removal of spent flowers, helps to stimulate the production of new flowers and prevents seed formation, thereby extending the flowering season. Prune the plant in late fall by cutting the stems back to the soil level. Mulch the plant's base to protect it from frost damage in winter.
Propagation of Cleome gossweileri Exell
Cleome gossweileri Exell, commonly known as Flamingo flower, is a flowering plant native to Angola. Propagation of Cleome gossweileri Exell can be done through various methods including seeds, cuttings, and division.
Propagation by Seeds
Propagation of Cleome gossweileri Exell by seeds is the most common method used. The seeds are obtained from mature plants and sown directly into the soil. It is important to ensure that the soil is well-draining and fertile for proper germination of the seeds. The seeds can be sown either in a pot or directly in the garden.
It is recommended to sow the seeds in the early spring, after the last frost in the area. The seeds should be covered lightly with soil and watered well. Germination of the seeds can take anywhere between 7 to 14 days, depending on the environment. Once the seedlings are about 2 inches tall, they can be transplanted into individual pots or the garden.
Propagation by Cuttings
Propagation of Cleome gossweileri Exell can also be done through cuttings. This method involves taking a cutting from the stem of a mature plant and rooting it in soil.
To take a cutting, select a healthy stem and cut it just below a leaf node. Remove all the leaves except for a few at the top. Dip the cut end of the stem into rooting hormone and plant it in well-draining soil. Water the soil well and cover the cutting with a plastic bag to increase humidity. The cutting should be kept in a warm, bright place until roots develop, which can take about 3-4 weeks. Once the roots are well-established, the cutting can be transplanted into a pot or the garden.
Propagation by Division
Propagation of Cleome gossweileri Exell by division is another method that can be used. This method involves dividing the roots of a mature plant and replanting them to create new plants.
To propagate the plant by division, dig up the mature plant, being careful not to damage the roots. Gently separate the roots into smaller sections, making sure that each section has some stems and leaves. Replant the sections in well-draining soil and water well. It is recommended to do this in the spring or fall when the plant is not actively growing.
By using the aforementioned propagation methods, it is possible to grow multiple Cleome gossweileri Exell plants from a single mature plant.
Disease and Pest Management for Cleome gossweileri Exell
