Tricolor Asiatic Jasmine, known scientifically as Trachelospermum asiaticum ‘Tricolor’, is an evergreen groundcover valued for its unique foliage. It provides continuous interest throughout the year and its adaptability makes it a sought-after plant for enhancing diverse garden landscapes.
Characteristics of Tricolor Asiatic Jasmine
Tricolor Asiatic Jasmine is distinguished by its vibrant, variegated foliage, displaying a mix of green, creamy white, and pink hues. New growth often emerges with prominent pink and white tones, maturing to a deeper green with white variegation. The pink coloration deepens in cooler weather, particularly in fall and winter.
This plant exhibits a dense, spreading growth habit, forming a low-lying carpet of foliage. While primarily grown for its ornamental leaves, it can produce small, star-shaped, fragrant white or cream-colored flowers in late spring or summer, though these are sporadic.
Planting and Care Guide
Light Requirements
Tricolor Asiatic Jasmine adapts to various light conditions, performing well in full sun to partial shade. For optimal color vibrancy, especially the pink and white variegation, partial shade or morning sun with afternoon shade is preferred. Insufficient light may reduce blooming, but the foliage remains its primary appeal.
Soil Preferences
This plant thrives in well-draining soil rich in organic matter. A slightly acidic to neutral pH (6.0-7.0) is suitable. To improve soil fertility and drainage, amend garden beds with compost or well-rotted manure before planting. For containers, a high-quality potting mix with added perlite or sand promotes adequate drainage.
Watering Needs
Consistent watering is important, especially during establishment. Newly planted jasmine benefits from consistently moist soil for the first few months to encourage strong root development. Once established, the plant becomes more drought-tolerant, but water when the top inch or two of soil feels dry. Avoid overwatering to prevent root rot and ensure the soil is never waterlogged.
Fertilization
Tricolor Asiatic Jasmine benefits from regular feeding during the growing season (spring through summer). Apply a balanced, water-soluble fertilizer (e.g., 10-10-10 blend) every 4 to 6 weeks. Alternatively, use a slow-release granular fertilizer at the beginning of the growing season. Avoid over-fertilization, as it can promote excessive foliage growth at the expense of blooms.
Pruning for Health and Appearance
Regular pruning helps maintain the desired shape and density. The optimal time for pruning is late winter or early spring before new growth begins. This removes dead, damaged, or diseased branches, promoting overall plant health. Light, ongoing pruning throughout the growing season keeps the plant tidy and encourages bushier growth.
Winter Hardiness
Tricolor Asiatic Jasmine is hardy in USDA Zones 7 through 11, tolerating temperatures down to -12°C to -15°C. In colder regions (below USDA Zone 7), grow it in containers and bring indoors during winter to protect from freezing. Providing shelter from strong, cold winds also contributes to its winter survival.
Common Landscape Uses
Tricolor Asiatic Jasmine is versatile for various landscape applications. Its dense, spreading nature makes it an excellent groundcover, suppressing weeds. The plant’s trailing habit also lends itself to spilling over walls, raised beds, containers, and hanging baskets, creating an attractive visual effect.
Beyond ornamental appeal, this jasmine can be used for erosion control on slopes and embankments due to its spreading root system. It can also be trained to climb trellises or fences, though it is a slower climber than other jasmine varieties. Its ability to form a low carpet or short hedge makes it suitable for borders and mass plantings.
Addressing Common Problems
A common issue is the loss of distinctive variegation, where leaves revert to solid green. This often occurs with too much shade, as sufficient light is needed to maintain vibrant pink and white hues. Moving the plant to a location with more light can restore its color.
Tricolor Asiatic Jasmine can be affected by pests and diseases. Common pests include aphids, spider mites, and scale insects, which cause leaf damage or discoloration. Inspecting regularly and treating infestations with insecticidal soap or neem oil manages these issues.
Fungal diseases, such as leaf spot or powdery mildew, occur in humid conditions with poor air circulation. Ensuring good air circulation and avoiding overhead watering prevents these problems.
Root rot results from overwatering or poorly draining soil. Improving soil drainage and maintaining appropriate watering practices are key preventative measures.
