Origin
Helichrysum pumilio (O.Hoffm.) Hilliard & B.L.Burtt subsp. pumilio, commonly referred to as dwarf everlasting, is a plant species that is native to South Africa.
Common Names
Dwarf everlasting is also commonly known as the Cape Gold, Little Yellow Bells, and the Dwarf Strawflower.
Uses
The plant is mostly used for decorative purposes. It is a great plant for garden beds and borders as it produces masses of bright yellow flowers that bloom from late spring to summer. The flowers can also be used as a cut flower as they can last for weeks when dried. Dwarf everlasting is also said to have some medicinal values, such as treating coughs and colds.
General Appearance
Dwarf everlasting is an evergreen perennial plant that grows up to 30 cm tall. The plant has a woody base, and it forms a dense and mat-like growth. The foliage is silver-grey and has small, narrow leaves. The flowers, which bloom in summer, are small and bright yellow and are held on long stems above the leaves. The plant's roots are fibrous, allowing it to form a dense mat on the ground, which makes it ideal for use as groundcover.
Light Requirements
Helichrysum pumilio subspecies pumilio requires full sunlight exposure for optimal growth and development. It cannot tolerate any shade, and reduced light levels can lead to stunted growth or leggy plants. Ideally, H. pumilio should receive at least six hours of direct sunlight every day.
Temperature Requirements
H. pumilio thrives in temperate climates and can tolerate occasional freezes. However, it grows best between 15°C and 30°C and cannot survive extremely high temperatures. In regions with hot summers, it is advisable to plant H. pumilio in a location that receives cool afternoon shade.
Soil Requirements
This plant prefers well-drained sandy soils, but it can grow in rocky, clay, or loamy soils as long as the drainage is sufficient. H. pumilio does not tolerate waterlogging or standing water, and wet soils can lead to root rot or other diseases. It requires a soil pH between 6.0 and 7.5 and can benefit from occasional fertilization with a balanced fertilizer.
Cultivation methods
Helichrysum pumilio (O.Hoffm.) Hilliard & B.L.Burtt subsp. pumilio, commonly known as the dwarf everlasting or the silver-bush everlasting, is a small, shrubby plant that belongs to the family Asteraceae. The plant grows well in well-drained, sandy soils and is tolerant of both drought and frost. It requires full sun to thrive and, once established, is relatively low maintenance.
Propagation of Helichrysum pumilio is best done from seeds. Directly sow the seeds in the soil as soon as the soil temperature is above 15 degrees Celsius. Alternatively, propagate from cuttings taken in spring or summer.
Watering needs
Helichrysum pumilio is drought-tolerant but still requires regular watering, especially during the first year after planting. Water the plant deeply and allow the soil to dry out slightly before watering again. Avoid overhead watering to prevent the leaves from becoming waterlogged.
Fertilization
The plant does not require regular fertilization. However, if you want to encourage healthy growth, a slow-release fertilizer applied during the growing season can be beneficial. Be careful not to over-fertilize, as it can lead to excessive leaf growth and reduced flowering.
Pruning
Pruning Helichrysum pumilio is not required, but it can help maintain the plant's shape and encourage bushy growth. Lightly trim the tips of the stems after flowering has ended, cutting back no more than one-third of the plant's height. Remove dead or damaged stems as necessary, taking care not to remove too much foliage, as this can reduce the plant's vigor.
Propagation of Helichrysum pumilio subsp. pumilio
Helichrysum pumilio is a low-growing, evergreen shrub that is native to South Africa. The species can be propagated by cuttings, division, or seed.
Propagation by Cuttings
Cuttings can be taken from Helichrysum pumilio in the spring or summer months. The cuttings should be taken from new growth on the plant and should be about 2-3 inches in length.
The cuttings should be dipped in a rooting hormone and then planted in a well-draining soil mix. The soil should be kept moist but not too wet, and the cuttings should be kept in a warm, bright location. Roots should start to form within a few weeks.
Once the cuttings have established roots, they can be transplanted into individual containers or into the ground.
Propagation by Division
Helichrysum pumilio can also be propagated through division. This is best done in the spring or fall.
To divide the plant, gently dig up the entire plant and then separate the root ball into smaller sections. Each section should have some leaves and roots attached.
The divided sections can then be planted in their new location. It is important to keep the soil moist and to provide some shade for the newly planted sections until they become established.
Propagation by Seed
Helichrysum pumilio can be grown from seed. The seeds can be planted directly in the ground or started indoors in pots.
If starting the seeds indoors, plant them in a well-draining soil mix and keep them moist. The pots should be kept in a warm, bright location until the seedlings emerge.
Once the seedlings have emerged, they can be transplanted into individual containers or into the ground.
Disease Management
Helichrysum pumilio is generally a healthy plant that is not affected by many diseases. However, some common fungal diseases that might affect the plant include:
- Botrytis Blight: This disease is characterized by grayish-brown patches on leaves and stems. It can be managed by removing infected plant parts and providing better air circulation.
- Powdery Mildew: This disease appears as a white powdery substance on the leaves. It can be treated with fungicides containing sulfur or neem oil.
- Root Rot: This disease causes the roots to rot, resulting in stunted growth and wilting. It can be avoided by providing well-draining soil and avoiding overwatering.
Pest Management
Helichrysum pumilio is also susceptible to some pests, such as:
- Aphids: These small insects feed on the sap of the plant and can be managed by using insecticidal soap or neem oil.
- Spider Mites: These pests spin webs on the leaves and cause discoloration. They can be managed by washing the plant with water and using insecticidal soap.
- Thrips: These tiny insects feed on the leaves and flowers, causing deformed growth. They can be managed by using insecticidal soap or neem oil.
Regular monitoring of the plant can help to detect diseases and pests early, making it easier to manage them. Additionally, keeping the plant healthy by providing proper care, such as watering and fertilizing, can also help prevent diseases and pests.
