Origin and Common Names
Evolvulus capensis E.Mey. ex Choisy is a species of flowering plant native to South Africa. It is commonly known as Blue Daze, Cape Dwarf Morning Glory, or just Dwarf Morning Glory.
Appearance
Evolvulus capensis is a small, spreading, herbaceous plant that reaches a height of only about 30cm. It has small, bright blue flowers that bloom in the summer months, from October to May. The flowers have five petals and a yellow center. The plant has green leaves that are oval-shaped and arranged alternately along the stems.
Uses
Evolvulus capensis is commonly used as a ground cover or border plant in gardens and landscapes. It is also used in hanging baskets and containers. The plant is drought-tolerant and does well in full sun to partial shade. It is easy to grow and requires minimal maintenance. Evolvulus capensis is also grown as an ornamental plant for its attractive flowers and foliage.
Light Requirements
Evolvulus capensis is a sun-loving plant that requires full sunlight exposure to grow best. It can tolerate partial shade, but too much shade will result in stunted growth and fewer blooms. Therefore, it is ideal for planting in open areas with direct access to sunlight.
Temperature Requirements
The plant thrives in warm temperatures ranging from 20°C - 30°C (68°F - 86°F). It can withstand colder temperatures of up to 10°C (50°F) but becomes dormant during the winter months. It is essential to keep the plant protected from frost and cold winds that can cause damage or kill the plant.
Soil Requirements
Evolvulus capensis prefers well-draining, sandy soil rich in organic matter. The soil should have a pH level of about 6.0 – 7.5 to promote good growth. It is essential to maintain adequate soil moisture levels while avoiding water-logging or soil-compaction that can be detrimental to the plant's growth. Adding compost or mulch to the soil can help improve moisture retention and fertility.
Cultivation methods
Evolvulus capensis E.Mey. ex Choisy, commonly known as Cape blue-eyed grass, is a lovely, evergreen herbaceous perennial plant that prefers warm temperatures and bright sunlight. It grows best in well-draining, moderately fertile soil in partially shaded to fully sunny locations.
To cultivate Evolvulus capensis, prepare a soil bed by loosening the soil to a depth of at least 8 inches and mixing in organic compost and organic matter like peat moss. Sow the seeds 2 inches deep and 12 inches apart in late spring. Seedlings can be transplanted once they reach a height of 4 inches.
Watering needs
Evolvulus capensis requires regular watering to support its growth and development. During the growing season, water the plant every other day to keep the soil moist.
However, avoid overwatering the plant as it may lead to root rot and fungal diseases. Ensure that the soil is well-drained, and avoid standing water around the roots. Water the plant sparingly during the winter season as the plant goes into a dormant phase.
Fertilization
Applying a slow-release balanced fertilizer once a month during the growing season can be beneficial to the growth and blooming of the Evolvulus capensis plant. Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium.
Avoid over-fertilization as it can cause damage to the plant and lead to the depletion of nutrients from the soil.
Pruning
Pruning helps to promote the bushy growth of the plant and encourages blooming. Evolvulus capensis requires pruning after blooming to remove the spent flowers and dead stems. Pinching off the growing tips of the stems can help to promote the formation of new branches.
Prune the plant in early spring before new growth appears, and avoid pruning during the winter dormancy phase.
Propagation of Evolvulus capensis E.Mey. ex Choisy
Evolvulus capensis E.Mey. ex Choisy can be propagated through both sexual and asexual methods.
Sexual Propagation
The plant produces seeds that can be sown directly in the ground or in pots filled with well-draining soil. The best time for sowing is spring or early summer, when the temperature is warm. The seeds should be covered with a thin layer of soil, watered gently, and kept in a warm and bright location. Germination usually takes place within 10-20 days.
Asexual Propagation
Evolvulus capensis E.Mey. ex Choisy can also be propagated through asexual methods such as stem cuttings and layering.
Stem cuttings can be taken from a healthy, mature plant in late spring or early summer. The cuttings should be about 10-15 cm long with a few leaves attached. Remove the lower leaves and dip the cut end in a rooting hormone powder. Plant the cutting in well-draining soil and keep it in a bright location, but out of direct sunlight. Water the cutting regularly and mist the leaves to keep them hydrated. Roots should develop in about 4-6 weeks.
Layering involves bending a low-growing stem of the plant to the ground and burying a portion of it in the soil, leaving the tip exposed. Peg the stem in place and keep the soil moist. Rooting should occur in a few weeks and the new plant can be separated from the mother plant once it has established a good root system.
Disease and Pest Management for Evolvulus capensis E.Mey. ex Choisy
Evolvulus capensis E.Mey. ex Choisy, commonly known as blue daze or Cape dwarf morning-glory, is a low-growing perennial plant that is native to South Africa. To maintain its health and vigor, it's important to be familiar with the common diseases and pests that can affect the plant and to manage them effectively.
Common Diseases
One of the most common diseases that can affect Evolvulus capensis is root rot. This is usually caused by overwatering or poor drainage, which can lead to the accumulation of water in the soil, creating the perfect environment for fungal growth. Symptoms of root rot include yellowing and wilting of the leaves, stunted growth, and a foul odor coming from the soil. To manage root rot, it's important to improve the drainage of the soil and avoid overwatering the plant. In severe cases, the affected parts of the plant may need to be removed, and the plant should be treated with a fungicide.
Another fungal disease that can affect Evolvulus capensis is powdery mildew. This disease is characterized by a white powdery coating on the leaves, stems, and flowers of the plant. It can be caused by a range of fungal species and is favored by high humidity and warm temperatures. To prevent powdery mildew, it's important to ensure that the plant is not overcrowded, and there is adequate air circulation. In case of infection, the affected parts of the plant can be removed, and the plant can be treated with a fungicide.
Common Pests
Evolvulus capensis is relatively resistant to pests and diseases. However, it can be occasionally affected by a few common pests, such as spider mites and aphids. Spider mites are tiny arachnids that suck the sap from plant leaves, causing them to turn yellow and dry out. These pests thrive in dry and dusty conditions. Regular spraying of the plant or wiping it with a damp cloth can help to control spider mites infestation.
Aphids are small, soft-bodied insects that suck the sap from plant leaves and stems. They can be identified by their pear-shaped bodies and long antennae. The damage caused by aphids manifests as the curling and yellowing of leaves, as well as stunted growth. To manage aphids on Evolvulus capensis, it's important to physically remove the insects by spraying the plant with a jet of water or using insecticidal soap.
Overall, by being aware of the common diseases and pests that can affect Evolvulus capensis, gardeners can make informed decisions about its management. By taking appropriate measures to monitor and manage these problems, gardeners can promote healthy growth and a long life for these beautiful plants.
