Besides Brown-eyed Susan, Beckera petiolaris has other common names, including the Orange Rudbeckia and the Green-eyed Susan. Additionally, in Swahili, it is known as "Msihiri," which means "to stay awake."
Appearance
Beckera petiolaris typically grows as an annual or short-lived perennial and can reach a height of approximately 2 feet. The plant boasts pinnately lobed green leaves with toothed margins and hairy stems. The flowers grow in solitary and measure up to 1 inch in diameter with narrow petals that curl downward. The flowers have black centers, surrounded by light orange or yellow petals.
Uses
Beckera petiolaris has some medicinal properties, and in traditional African medicine, people use its leaves and roots to treat various ailments such as measles and heart-related diseases. The plant is also known to have insecticidal properties that make it useful in controlling pests. In addition, the plant's aesthetic value has made it a popular ornamental plant in many gardens and landscapes, where it can be grown from seeds.
Light Requirements of Beckera Petiolaris (Hochst.) Hochst.
Beckera petiolaris (Hochst.) Hochst. thrives in moderate to bright light conditions. It is ideal to keep this plant in a well-lit area with indirect sunlight. If the plant is exposed to direct sunlight, it may cause leaf scorching, and the growth of the plant may be impaired.
Temperature Requirements of Beckera Petiolaris (Hochst.) Hochst.
The optimal temperature range for Beckera petiolaris (Hochst.) Hochst. to grow is between 60-85°F (15-29°C). It is sensitive to drastic temperature fluctuations, so it is best to maintain a consistent temperature. In colder temperatures, it may go into dormancy, but it will continue to grow once the temperature becomes suitable.
Soil Requirements of Beckera Petiolaris (Hochst.) Hochst.
Beckera petiolaris (Hochst.) Hochst. thrives in well-draining, nutrient-rich soil. The plant prefers slightly acidic to neutral soil with a pH level of 6.0-7.5. The soil should have good water retention properties and be rich in organic matter. It is essential to avoid over-watering the plant, which can lead to root rot.
Cultivation Methods
Beckera petiolaris or the Silver-leaved cabbage or Sand-dune beckera grows well in sandy soils in hot and dry conditions. These plants are exceptionally drought tolerant and adaptable although they thrive best in well-drained soils. Although they are a hardy species, they need to be protected from heavy frost in extremely cold climates.
Watering Needs
These plants are native to arid conditions, so they require only minimal watering. The plants should be watered only when the soil gets dry. It's recommended to water this plant once every fortnight or every month. Overwatering causes the soil to be too wet, which can lead to root rot and other issues.
Fertilization
Beckera petiolaris responds well to occasional feeding. A slow-release general-purpose fertilizer would be suitable, and it should be applied once a month during the growing season. Too much fertilizer can cause leggy growth and fewer flowers.
Pruning
These plants require minimal maintenance, and pruning is not necessary. However, if the plants become too leggy or overgrown, cutting them back by half will encourage bushier growth and more blooms. It's best to do this in early spring, just before the plant starts to shoot new growth.
Propagation Methods of Beckera petiolaris (Hochst.) Hochst.
Beckera petiolaris (Hochst.) Hochst., commonly known as the African succulent, is a hardy perennial plant that belongs to the family Acanthaceae. This plant is endemic to Southern Africa and is often grown as an ornamental plant in gardens and greenhouses. The following are the methods used for propagating Beckera petiolaris.
Seed Propagation
Seed propagation is the easiest and most common method of propagating Beckera petiolaris. The plant produces numerous small seeds that can be collected from the dried seed capsules. The seeds should be sown in a well-draining soil mix and covered lightly with soil. They should be kept moist and warm, and they will germinate within two weeks.
Cuttings Propagation
Beckera petiolaris can be propagated by stem cuttings. The stem cuttings should be taken from a healthy stem and should be at least 10 cm long. Remove the leaves from the lower part of the stem, leaving only two to three pairs of leaves on the upper part. Dip the cut end of the stem in rooting hormone powder and plant it in a well-draining soil mix. Keep the soil moist and warm, and the cutting will root within two to three weeks.
Division Propagation
Division propagation is a method that is used for mature Beckera petiolaris plants that have grown into clumps. The plant should be carefully dug up and gently separated into smaller clumps. Each clump should be planted in a well-draining soil mix and watered regularly until it establishes itself.
Grafting Propagation
Grafting propagation is not a common method for propagating Beckera petiolaris. However, it is a useful method for maintaining rare or endangered varieties. Grafting involves joining the stem of the Beckera petiolaris plant onto the stem of a closely related plant. The joined plant should be allowed to grow until it establishes itself.
Disease and Pest Management for Beckera petiolaris (Hochst.) Hochst.
Beckera petiolaris (Hochst.) Hochst. is a flowering plant that belongs to the family Acanthaceae. It is native to Africa and is commonly known as the button flower. Like any other plant, it is susceptible to diseases and pests. Here are common diseases and pests that could infect this plant and ways to manage them:
Common Diseases
Root Rot: Root rot is a fungal disease that thrives in wet conditions. Symptoms of root rot include yellowing leaves, wilting, and stunted growth. To manage root rot, avoid overwatering the plant and ensure that the soil has adequate drainage. Remove infected plants and dispose of them far away from the garden to avoid spreading the disease.
Leaf Spot: Leaf spot is a fungal disease that appears as brown or black spots on the leaves. It occurs in humid conditions. To manage leaf spot, remove infected leaves and destroy them. Proper spacing between plants and ensuring good air circulation can help prevent the disease from spreading.
Powdery Mildew: Powdery mildew is a fungal disease that manifests as white or grayish spots on the leaves, stems, and flowers. It occurs in warm and dry conditions. To manage powdery mildew, ensure that there is good air circulation and avoid overhead watering. Remove infected plants and destroy them. Fungicides can also be used, but they are most effective when applied early in the development of the disease.
Common Pests
Aphids: Aphids are tiny insects that suck out the sap from the plant. They are usually found on the underside of leaves. Symptoms of aphid infestation include curling leaves, stunted growth, yellowing, and distorted leaves. To manage aphids, use insecticidal soap, Neem oil, or release predatory insects that feed on aphids.
Spider Mites: Spider mites are tiny creatures that feed on the underside of leaves. They cause discoloration of leaves and webbing. To manage spider mites, use insecticidal soap, Neem oil, or predatory insects to control their population.
Mealybugs: Mealybugs are white, cotton-like insects that suck the sap from the plant and transmit diseases. To manage mealybugs, apply insecticidal soap or Neem oil. Predatory insects, like ladybugs, can also be released to control their population.
It is important to note that the best way to manage diseases and pests in any plant is prevention. Proper care and maintenance of the plant and its surroundings can help prevent the occurrence of diseases and pests, ensuring a healthy and vibrant plant.
