It grows in rocky and arid habitats, and it is a wild shrub that is widely cultivated for its essential oil.
Common Names
The plant is commonly known as the Egyptian everlasting, desert gold, and the aromatic helichrysum. In North Africa, it is referred to as “Siwa peppermint.”
Uses
The plant has a long history of use in traditional medicine and aromatherapy. The essential oil obtained from its dried leaves is known to have powerful anti-inflammatory, antifungal, and antispasmodic properties. The essential oil is also used in perfumes and cosmetics due to its pleasant fragrance. The plant is also used in herbal medicine to treat respiratory problems, colds, coughs, and bronchitis. In Africa, the plant is brewed as tea, which is believed to stimulate digestion, ease arthritis, and soothe a sore throat.
General Appearance
Helichrysum forskahlii (J.F.Gmel.) Hilliard & B.L.Burtt var. forskahlii is a small bushy plant with woody stems that can grow up to 50 cm tall. The leaves are small, aromatic, and covered with tiny hairs. The flowers are small, bright yellow, and arranged in small clusters at the end of branches. The small flowers bloom in summer and autumn, and they retain their color and shape when dried, making them ideal for floral arrangements and wreaths. The plant has a distinctive pleasant fragrance that resembles a mix of peppermint and chamomile.
Light Requirements
Helichrysum forskahlii var. forskahlii typically prefers full sun to partial shade. The plant requires at least 6 hours of direct sunlight daily. If grown indoors, placing the plant near a sunny window or using artificial grow lights can provide sufficient sunlight for the plant's growth.
Temperature Requirements
The plant requires warm temperatures to grow and flourish. The ideal temperature range for Helichrysum forskahlii var. forskahlii growth is between 18°C to 24°C. The plant cannot tolerate frost or extreme heat. If grown outdoors in regions with frost, it is best to grow the plant in a container to move it indoors during the winter months.
Soil Requirements
Helichrysum forskahlii var. forskahlii prefers well-drained soil that is rich in nutrients. The soil pH should be between 6.0 to 7.5. The plant can tolerate dry soil conditions, but not waterlogged soil. Adding compost or other organic matter to the soil can increase its nutrient content, boosting plant growth. It is best to avoid heavy clay soil as it may cause drainage issues.
Cultivation Methods
Helichrysum forskahlii (J.F.Gmel.) Hilliard & B.L.Burtt var. forskahlii is a plant species that thrives in warm and dry environments. It grows best in well-draining soil with a pH between 6.0 and 7.5. The plant prefers full sun to partial shade and can tolerate a range of temperatures. The best way to cultivate Helichrysum forskahlii is to plant it from seedlings or cuttings in spring or early summer. The plant requires proper spacing to prevent overcrowding and ensure good air circulation.
Watering Needs
Helichrysum forskahlii is a drought-tolerant plant; therefore, it requires minimal watering. Overwatering the plant can lead to root rot, causing stunted growth and eventually plant death. It is recommended to water the plant deeply once per week or every ten days, depending on the weather conditions. The soil should be allowed to dry out somewhat between watering.
Fertilization
Helichrysum forskahlii does not require regular fertilization. However, adding a small amount of balanced fertilizer (10-10-10) during planting can help promote healthy growth. The fertilizer should be applied at a rate of 1/4 cup per square foot of soil around the base of the plant. Over-fertilizing the plant can lead to excessive foliage growth and reduced flowering.
Pruning
Helichrysum forskahlii requires minimal pruning. However, it is important to remove any dead or damaged leaves or stems promptly. Pruning is also essential to maintain an attractive growth habit and encourage branching. Pruning should be done in late winter or early spring before new growth appears.
Propagation of Helichrysum forskahlii var. forskahlii
Helichrysum forskahlii var. forskahlii, commonly known as the 'shrubby everlasting,' is a herbaceous perennial plant with a woody base and silver-grey foliage. The plant produces yellow flowers with a papery texture, which make for excellent cut flowers. Propagation of this plant is crucial to maintain the species and to create new plants with desired traits.
Propagation Methods
There are different methods of propagating Helichrysum forskahlii var. forskahlii, including by seeds, stem cuttings, and root cuttings.
Propagation by Seeds
Seeds are readily available and easy to grow. For best results, sow fresh seeds indoors in a well-draining soil mix, covered with a thin layer of soil or vermiculite. Keep the soil moist, and place the container in a warm and bright location. The optimal temperature for germination is between 20°C and 25°C.
Propagation by Stem Cuttings
Stem cuttings taken from the upper part of the plant, including a node and two to three pairs of leaves, are ideal for propagation. Dip the cut ends into a rooting hormone, and plant them in a well-draining soil mix. Keep the soil moist, and place the container in a warm and bright location. The cuttings should root in two to four weeks.
Propagation by Root Cuttings
You can propagate Helichrysum forskahlii var. forskahlii through root cuttings, but this method requires more time and patience. Dig up a clump of the plant, and separate the roots. Cut the roots into sections, each with two to three buds and plant them in a well-draining soil mix. Keep the soil moist and in a warm location. The cuttings should grow within six to eight weeks.
Disease and Pest Management for Helichrysum forskahlii (J.F.Gmel.) Hilliard & B.L.Burtt var. forskahlii
Helichrysum forskahlii (J.F.Gmel.) Hilliard & B.L.Burtt var. forskahlii, otherwise known as the Egyptian Immortelle, is a hardy, drought-resistant shrub that is susceptible to certain pests and diseases. Proper disease and pest management is essential to maintain the health and appearance of the plant.
Common Diseases
One of the most common diseases that can affect Helichrysum forskahlii is powdery mildew. This fungal disease causes a white powdery coating to appear on the leaves and stems of the plant. To manage powdery mildew, it is best to remove and destroy any infected plant parts and to implement good ventilation and spacing practices to reduce humidity levels. Additionally, applying a fungicide can help to control and prevent the spread of the disease.
Another disease that can affect Helichrysum forskahlii is leaf spot. This fungal disease causes small spots to appear on the leaves of the plant, which can lead to defoliation and reduced growth. To manage leaf spot, it is best to remove and destroy any infected plant parts and to avoid overhead watering, as wet leaves can promote the development of the disease. Fungicide applications can also be effective in controlling and preventing leaf spot.
Common Pests
Helichrysum forskahlii can be susceptible to certain pests, including spider mites and mealybugs. Spider mites are tiny pests that feed on the leaves of the plant, causing them to appear speckled and discolored. To manage spider mites, it is best to remove and destroy any heavily infested plant parts and to apply a miticide to the plant.
Mealybugs are another common pest that can affect Helichrysum forskahlii. These pests are small, soft-bodied insects that feed on the sap of the plant, causing stunted growth and yellowing of the leaves. To manage mealybugs, it is best to remove and destroy any heavily infested plant parts and to apply an insecticide to the plant.
Implementing regular inspections and good cultural practices, such as proper watering and fertilization, can also help to prevent disease and pest infestations on Helichrysum forskahlii.
