Origin of Phylica axillaris Lam. var. densifolia Pillans
The species is native to South Africa where it is found in western and southern coastal regions of the country. It grows in sandy soils and is tolerant of salt spray and sea winds.
Physical characteristics
Phylica axillaris Lam. var. densifolia Pillans is a small evergreen shrub that grows up to 2 meters tall. It has a dense, bushy growth habit with stiff, wiry branches that spread outwards and upwards. The leaves are small, narrow and densely packed, arranged alternately on the branches.
The flowers are small and inconspicuous, produced in dense clusters at the leaf axils. They are greenish-yellow and are mainly wind-pollinated. The seeds are small and round, produced in capsules that split open when ripe.
Uses and Cultivation
Phylica axillaris Lam. var. densifolia Pillans is grown as an ornamental plant for its dense foliage and interesting growth habit. It is often used in rockeries, coastal gardens and as a hedge or screen. It is also used in the floristry industry for its long-lasting cut stem and small, wiry branches that add interest and texture to floral arrangements.
Phylica axillaris Lam. var. densifolia Pillans is easy to grow and is adaptable to a wide range of soil types, provided they are well-drained. It prefers full sun to partial shade and is drought tolerant once established. It can be propagated by seed or by taking semi-hardwood cuttings in late summer.
Light Requirements
Phylica axillaris Lam. var. densifolia Pillans thrives in full sunlight to partly shaded areas. It can tolerate some shade, but it prefers to receive direct sunlight. Therefore, it is ideal to plant it in a location that receives at least six hours of direct sunlight daily.
Temperature Requirements
This plant typically grows in areas with mild to warm temperatures. A temperature range of 18°C to 28°C (64°F to 82°F) is ideal for healthy growth. It can tolerate higher temperatures but may require frequent watering in hot, dry conditions. Conversely, it cannot withstand freezing temperatures and should not be exposed to frost. Therefore, the plant is best suited for USDA hardiness zones 9 to 11.
Soil Requirements
The plant requires well-draining soil with good air circulation. It cannot withstand waterlogged soils, as this can lead to root rot. A soil pH range of 5.5 to 7.5 is ideal for optimal growth. The soil should be rich in organic matter, but it should not be excessively fertile, as this can lead to vigorous vegetative growth and poor flowering.
Cultivation methods
Phylica axillaris Lam. var. densifolia Pillans, commonly known as cape myrtle, is a small evergreen shrub that requires sandy, well-draining soil to grow optimally. It is accustomed to dry summers and mild winters, making it an ideal addition to coastal gardens and rock gardens where the soil is light and well-draining. This plant requires full sun exposure to grow and thrive.
Watering needs
Phylica axillaris Lam. var. densifolia Pillans does not require regular watering once it is established in the ground. It has adapted to grow amid the sandy soils along the western coastal plains, which is an area that experiences very little rainfall. However, young plants benefit from regular watering until they are established in the ground. Water deeply and then let the soil dry completely before watering again to keep the roots from sitting in water, which can cause damage.
Fertilization
The plant Phylica axillaris Lam. var. densifolia Pillans has low nutrient requirements and does not need regular fertilization. However, applying a slow-release granular fertilizer with low nitrogen, moderate phosphorus, and high potassium levels once a year in early spring will help keep the plant healthy and vigorous. Alternatively, you can apply a liquid fertilizer monthly during the growing season, diluting it to half strength before applying to avoid damaging the roots.
Pruning
Pruning the plant Phylica axillaris Lam. var. densifolia Pillans is essential to keep it from becoming leggy and unsightly. Prune away any dead or diseased branches as soon as possible to prevent the spread of disease and pests. Additionally, prune away about a third of the plant's growth in late winter/early spring to promote bushier growth and stimulate new growth. Use sharp and clean pruning tools to avoid marring the bark or causing any damage to the plant during the pruning process.
Propagation of Phylica Axillaris Lam. var. Densifolia Pillans
Phylica Axillaris Lam. var. Densifolia Pillans is a popular evergreen plant found abundantly in the Western Cape Province of South Africa. The plant is propagated by both sexual and asexual means with varying levels of success.
Seed Propagation
The plant can be propagated from seeds collected from ripened fruit. The seeds must be soaked in water for at least an hour before sowing. Germination can take up to 3 months, and it is best done in the spring. The sowed seeds should be kept moist until germination occurs.
Cuttings Propagation
Softwood cuttings taken from healthy branches with a length of about 10-15 cm with at least two nodes can be used for propagation as well. The cuttings must be treated with rooting hormone and planted in well-draining media. High humidity is necessary for the cuttings to root, so the cuttings should be covered with a plastic bag or a transparent container to retain moisture. The cuttings take about 4-6 weeks to form roots and can be potted or transplanted to the field once well-established.
Grafting Propagation
Although grafting is not a common propagation technique for Phylica Axillaris Lam. var. Densifolia Pillans, it can be used to propagate plants in regions with poor soils or unfavorable climatic conditions. The plant can be grafted onto rootstock from the same plant species, which can improve the quality and yield of the plant. The grafted plant can be transplanted to the field after a year or two of growth.
Disease and Pest Management for Phylica axillaris Lam. var. densifolia Pillans
Phylica axillaris Lam. var. densifolia Pillans is a shrub that is prone to certain diseases and pests. Here are some of the common problems and ways to manage them:
Diseases
Leaf Spot
Leaf spot is a fungal disease that causes small, dark spots on the leaves. If not treated, it can cause the leaves to fall off. To manage this disease, remove the infected leaves and avoid overwatering the plant. Fungicides can also be used as a preventive measure.
Root Rot
Root rot is a common disease caused by overwatering and poor drainage. Signs of root rot include yellowing leaves and wilting. To manage this disease, make sure the soil is well-drained and avoid overwatering. If the plant is severely infected, it may need to be removed.
Powdery Mildew
Powdery mildew is a fungal disease that appears as a white, powdery substance on the leaves. To manage this disease, remove the infected leaves and avoid overhead watering. Fungicides can be used as a preventive measure.
Pests
Spider Mites
Spider mites are small pests that can cause significant damage to the plant. Signs of spider mites include yellow leaves and fine webbing on the plant. To manage this pest, use insecticidal soap or spray the plant with a strong stream of water to wash off the mites.
Caterpillars
Caterpillars can eat through the foliage of the plant, causing significant damage. To manage this pest, physically remove the caterpillars from the plant or use a pesticide designed for caterpillar control.
Scale Insects
