The leaves are simple and oval-shaped, measuring about 2-3 cm in length. They are arranged in an alternate pattern and are also covered in small, stiff hairs. The flowers of the flattened heliotrope are small and white, growing in clusters at the end of the branches. Each flower measures about 3 mm in diameter and has 5 fused petals.
Uses
The flattened heliotrope has a variety of traditional medicinal uses. In some African cultures, the roots of the plant are boiled and consumed to treat stomach ailments, while other parts of the plant are used to treat fever, coughs, and skin conditions. The plant also has several non-medicinal uses. Its branches are used to make walking sticks, while the leaves and flowers are an important addition to traditional African herbal baths.
Common Names
In addition to flattened heliotrope, Heliotropium applanatum is known by several other common names, including African turnsole and spiny heliotrope.
Typical Growth Conditions of Heliotropium applanatum Thulin & Verdc.
Heliotropium applanatum Thulin & Verdc. is a plant species that typically grows in rocky areas and hillsides. Its favorable growth condition is generally characterized by specific environmental factors.
Light Requirements
The plant requires full sunlight to partial shade to sustain growth. It is best to plant in locations with sufficient light that ranges from 6-8 hours a day. Low light conditions hinder growth and development, leading to stunted growth.
Soil Requirements
The plant prefers well-drained soils composed of loamy, gravelly, or sandy soils. The ideal pH range for the plant is moderately acidic to neutral (5.5-7.5 pH). With its preference for rocky terrains, it's also essential to ensure that the soil contains enough organic matter to provide the required nutrients.
Temperature Requirements
Heliotropium applanatum Thulin & Verdc. can adapt to a wide range of temperature conditions. However, it grows optimally at a temperature range of 15-30°C (59-86°F). At high temperatures, the plant tends to produce fewer leaves and flowers, which may impact its overall performance.
Water Requirements
The plant requires moderate watering to thrive. Regular watering during the growing season helps to ensure that the soil remains moist but not waterlogged. During extreme drought conditions, the plant may wilt, leading to reduced growth and yield.
Fertilizer Requirements
Heliotropium applanatum Thulin & Verdc. does not require heavy fertilization. However, it is essential to add a light application of well-balanced fertilizer during the growing season to boost growth and improve plant health.
Overall, Heliotropium applanatum Thulin & Verdc. is a relatively hardy plant with low maintenance requirements. By following the typical growth conditions, gardeners and farmers can achieve optimal growth and yield of the plant.
Cultivation Methods
Heliotropium applanatum Thulin & Verdc., also known as flat heliotrope, is a species of flowering plant that is relatively easy to cultivate. The best location for planting this species should be in a sunny to lightly shaded area with well-draining soil. It is also essential to provide enough space when planting Heliotropium applanatum Thulin & Verdc. in a garden bed or container to ensure proper growth and development.
You can propagate Heliotropium applanatum Thulin & Verdc. using seeds or cuttings. Propagation using seeds requires that the seeds be sown directly into the soil in spring or early summer. Cuttings of the plant should be taken during the growing season and rooted in well-draining soil in a bright, shaded location. Once rooted, the cuttings can be transplanted to the sunnier location.
Watering Needs
Flat heliotrope requires moderate watering during the growing season. It is essential to keep the soil consistently moist but not waterlogged, especially during the hotter months. Therefore, it would be best to plant the heliotrope in a well-draining soil mix. When watering, avoid getting the foliage wet to prevent fungal infections.
Fertilization
Heliotropium applanatum Thulin & Verdc. responds well to moderate applications of balanced fertilizer during the growing season. You can feed the plant using a balanced fertilizer every four to six weeks during the growing season. It is essential to follow the manufacturer's instructions on the application rate of the fertilizer.
Pruning
The best time to prune Heliotropium applanatum Thulin & Verdc. is in late winter or early spring when the plant is still dormant. To promote bushy growth, you should pinch out the tips of the growing shoots, leaving a minimum of two nodes on each stem. Deadheading spent flowers and removing any yellowing or diseased foliage will help encourage the plant to continue blooming and remain healthy.
Propagation of Heliotropium applanatum Thulin & Verdc.
Heliotropium applanatum Thulin & Verdc., commonly known as the button heliotrope, is a small perennial herb that grows in poor soils in semi-arid regions of eastern and southern Africa. The plant is propagated through seeds and stem cuttings.
Propagation by Seeds
The button heliotrope produces small, black, shiny seeds that are dispersed by the wind and can easily germinate in the wild. In cultivation, seeds can be collected from mature plants and sown in seed trays filled with a well-draining potting mix. The seeds should be sown at a depth of about 2mm and covered with a thin layer of sand. The trays should be kept moist and placed in a warm and bright area. Germination can take about two to three weeks. After germination, the seedlings can be transplanted into individual containers or directly into the garden.
Propagation by Stem cuttings
The button heliotrope can also be propagated by stem cuttings taken from mature plants. The best time to take cuttings is during the growing season when the plant is actively growing. A stem cutting of about 10cm in length should be taken, and the lower leaves should be removed. The cutting should be dipped in rooting hormone and planted in a well-draining potting mix. The cutting should be kept moist and placed in a warm and bright area. Roots should begin to develop in about 2-3 weeks, and the cutting can be transplanted into individual containers or directly into the garden.
With proper care, both seed propagation and stem cutting propagation methods can produce healthy and vigorous button heliotrope plants.
Disease and Pest Management for Heliotropium applanatum
Although Heliotropium applanatum is a hardy plant, it can still be affected by pests and diseases. Here are some common issues and ways to manage them:
Pests
Spider mites: These tiny pests suck the sap from the leaves, causing them to turn yellow and become distorted. To manage them, spray the plant with insecticidal soap or neem oil.
Aphids: These sap-sucking pests can cause wilting and yellowing of the plant. Remove them by spraying the plant with a strong stream of water or by applying insecticidal soap.
Caterpillars: These voracious eaters can strip the leaves of the plant. To manage them, pick them off the plant by hand or apply Bacillus thuringiensis (BT) insecticide.
Diseases
Root rot: This fungal disease is caused by overwatering and poor drainage. To manage it, ensure the plant is not sitting in water and let the soil dry out between waterings. If the plant is severely affected, remove it and replant in fresh soil.
Powdery mildew: This fungal disease causes a white powdery coating on the leaves. To manage it, improve air circulation around the plant and remove affected leaves. Apply a fungicide if necessary.
Leaf spot: This bacterial disease causes brown spots on the leaves. To manage it, remove affected leaves and apply a copper fungicide.
By regularly monitoring your Heliotropium applanatum for pests and diseases and taking proactive measures to manage them, you can help keep your plant healthy and thriving.
