Wedelia is a genus of flowering plants in the family Asteraceae. The most well-known species within this genus is Wedelia trilobata, commonly known as Creeping Oxeye, Trailing Daisy, or Sphagneticola. Wedelia species are native to tropical and subtropical regions of the Americas and have been introduced to other parts of the world as ornamental plants and ground covers.
Landscape Use:
Wedelia trilobata is commonly used as a ground cover in gardens, landscapes, and urban areas, thanks to its rapid growth and attractive flowers.
It is often planted on slopes or embankments to help control erosion due to its dense mat-forming growth habit.
The plant’s bright yellow flowers and low-growing nature make it a popular choice for adding color to rock gardens, borders, and other sunny areas.
Note: While Wedelia trilobata is widely cultivated as an ornamental ground cover, it is important to exercise caution when planting it, as it can become invasive in some regions and may be considered an invasive weed in certain areas. Always check with local authorities or gardening experts to ensure that Wedelia is suitable for your specific location and to prevent it from spreading uncontrollably.
Here’s a detailed description of Wedelia trilobata:
Plant Characteristics:
Size: Wedelia trilobata is a low-growing perennial herbaceous plant that forms a dense mat or carpet. It typically grows to a height of 6 to 12 inches (15 to 30 cm) and can spread vigorously along the ground, covering a large area if left unchecked.
Leaves: The leaves of Wedelia trilobata are distinctive and trilobed (three-lobed), which gives rise to its specific name “trilobata.” The leaves are bright green, succulent, and have toothed edges. They are arranged alternately along trailing stems.
Flowers: The flowers of Wedelia trilobata are daisy-like, with bright yellow petals surrounding a dark yellow or orange center. The flowers are about 1 inch (2.5 cm) in diameter and occur singly or in small clusters at the tips of the stems. They bloom throughout the year in warm climates.
Growth Habit: Wedelia trilobata has a trailing or creeping growth habit, with stems that root at nodes when they come into contact with the ground. This rooting ability allows the plant to spread rapidly and form a dense ground cover.
Cultural Requirements:
Sunlight: Wedelia trilobata thrives in full sunlight. It is highly adaptable and can tolerate a wide range of light conditions, from full sun to partial shade.
Temperature: This plant is well-suited to warm and tropical climates, where temperatures remain above freezing. It is sensitive to frost and prefers frost-free regions.
Soil: Wedelia trilobata is not particularly picky about soil type and can grow in various soil conditions, but it prefers well-draining soils.
Watering: The plant is relatively drought-tolerant once established, but regular watering is necessary during the establishment phase.
Maintenance: Due to its aggressive spreading habit, Wedelia trilobata requires regular maintenance and control to prevent it from becoming invasive and crowding out other plants.
