General Appearance
The plant produces numerous stems that grow up to 60-80 cm in height and spread up to 30 cm wide. The leaves are grey-green, linear, and about 2-3 cm long, with hairs on the undersides, covered with silky hairs, giving a woolly appearance. The flowers are distinctive and arranged in small inflorescences, with a diameter of about 2.5 cm. The flowers range from yellow to orange, with a papery texture. The plant blooms throughout the year but primarily from winter to early summer.
Uses
Helichrysum obductum Bolus is commonly cultivated as an ornamental plant for cut flowers and its bright vivid display. Its flowers retain their color when dried and can last indefinitely. The dried flowers are used in potpourri and floral arrangements. The plant also has a medicinal history amongst the indigenous people of South Africa where it has been used to treat fever, coughs, colds, and chest complaints.
Light Requirements
Helichrysum obductum Bolus is a plant that requires full sun to grow. It needs to be exposed to direct sunlight for at least six hours a day. It is not advisable to grow this plant in shady areas as it may affect its flowering and growth. The plant also needs a lot of light to carry out photosynthesis, which is essential for its survival.
Temperature Requirements
Helichrysum obductum Bolus is a plant that is adapted to grow in hot and dry regions. It is a heat-loving plant that can tolerate high temperatures up to 30 °C. The plant requires a warm climate to grow and does not do well in regions with frost.
Soil Requirements
The plant prefers well-drained and sandy soils that are slightly acidic to grow. It can also grow in soils with a pH of between 6 to 7.5. The soils should not be water-logged as it can cause root rot and affect the growth of the plant. Helichrysum obductum Bolus requires moderate soil fertility and can tolerate moderately saline soils.
Cultivation
Helichrysum obductum Bolus, also known as Cape Strawflower, is a plant that thrives in well-draining soil and a sunny location in your garden. In order to grow Cape Strawflower successfully, sow the seeds in late spring or early summer in seed trays. Keep the soil moist and ensure that the temperature stays between 18°C and 24°C. When the seedlings have their first true leaves and are sturdy enough to handle, transplant to a larger pot with well-draining soil.
Watering Needs
Cape Strawflower requires moderate watering. However, it is advisable to water deeply and less frequently rather than shallowly and frequently. During the growing season, ensure the topsoil remains moist. In winter, reduce watering to avoid root rot. Also, ensure that your plants are not left standing in water as it may lead to root rot and other health issues.
Fertilization
It is essential to fertilize Cape Strawflower regularly. A good recommendation is to use a balanced fertilizer with N-P-K (nitrogen, potassium, and phosphorus) of 10-10-10 during the growing season. Apply the fertilizer every two to three weeks to promote healthy growth. In addition, if you notice the plants have stunted growth or discoloured leaves, it may be a sign of nutrient deficiency. Add a water-soluble fertilizer to the soil to compensate for the missing nutrients.
Pruning
Pruning is necessary to keep your Cape Strawflower from getting too leggy. Pinch back the tips of the stems regularly to encourage bushier growth, more branching, and more flowers. Also, deadheading helps to prolong flowering. Cut the stem just above where the flowers have faded. Engage in this activity regularly to ensure healthy growth and long-lasting beauty.
Propagation of Helichrysum obductum Bolus
Helichrysum obductum Bolus, commonly known as the grey everlasting or strawflower, is a perennial plant that belongs to the family Asteraceae. This plant is indigenous to South Africa and is popularly grown for its beautiful and long-lasting flowers.
Propagation methods
The following are some of the primary propagation methods used for Helichrysum obductum:
1. Seed propagation
One of the easiest methods of propagating Helichrysum obductum is through seed propagation. Seeds are readily available and can be sown in trays or shallow pots filled with compost. It is best to sow seeds in the summer or early autumn, and they should be placed in a warm and bright spot with good ventilation. Seeds will germinate in 10-14 days, and once seedlings are large enough, they can be planted into individual pots.
2. Stem cuttings
Another popular method of propagating Helichrysum obductum is through stem cuttings. Cuttings should be taken during the early summer months and should be approximately 5-10 cm in length. Remove the lower leaves and dip the cut end into rooting hormone before planting it into a pot filled with propagating mix. To improve the chances of success, use a heated propagator to ensure that the cuttings remain at a consistent temperature. Cuttings will root in 3-4 weeks, and once they are sufficiently rooted, they can be transplanted into individual pots.
3. Division
Division is another method of propagating Helichrysum obductum. It is best to do this during the late autumn or early spring months. To divide the plant, dig up the clump and remove the soil to expose the roots. Use a sharp and sterile knife or spade to cut the clump into smaller sections, each containing several stems and roots. Replant the sections into prepared soil in the garden or individual pots.
By utilizing these methods, it is possible to propagate Helichrysum obductum easily and successfully. Proper care and maintenance should be given to propagated plants to ensure optimal growth and flowering.
Disease and Pest Management for Helichrysum obductum Bolus
Helichrysum obductum Bolus, also known as the stiff everlasting, is a perennial plant that is native to South Africa. Like many plants, it is vulnerable to diseases and pests that can damage or kill it. Here are some common diseases and pests that can affect Helichrysum obductum Bolus and ways to manage them:
Diseases
One common disease that can affect Helichrysum obductum Bolus is powdery mildew. This fungal disease appears as a white or gray powdery coating on the leaves and can cause them to become distorted or yellowed. To manage powdery mildew, remove infected leaves and spray the plant with a fungicide containing potassium bicarbonate or neem oil.
Another disease that can affect Helichrysum obductum Bolus is stem rot. This can be caused by overwatering or poorly draining soil, which can create conditions ideal for fungal growth. To manage stem rot, remove infected parts of the plant and improve soil drainage. You can also use a fungicide containing copper or chlorothalonil.
Pests
One common pest that can affect Helichrysum obductum Bolus is spider mites. These tiny insects can create webbing on the leaves and cause them to become stippled or discolored. To manage spider mites, spray the plant with a strong stream of water to dislodge them and use an insecticidal soap or neem oil to kill them.
Aphids are another pest that can affect Helichrysum obductum Bolus. These small insects suck sap from the leaves and can cause them to become distorted or yellowed. To manage aphids, prune off heavily infested areas and spray the plant with a strong stream of water. You can also use insecticidal soap or neem oil to kill them.
By keeping an eye out for diseases and pests and taking proactive steps to manage them, you can help keep your Helichrysum obductum Bolus healthy and beautiful.
