Carolina jasmine and Star jasmine are two popular vines commonly found in gardens and landscapes. While they may share similar names and certain characteristics, they are actually different plants. Let’s explore their differences in more detail.
1. Botanical Classification:
Carolina jasmine, also known as Carolina jessamine, is scientifically called Gelsemium sempervirens. On the other hand, Star jasmine is scientifically known as Trachelospermum jasminoides. Despite their common names, neither of these plants are true jasmines.
2. Appearance:
Carolina jasmine is an evergreen vine that features bright yellow, trumpet-shaped flowers. These flowers are typically fragrant and bloom in late winter or early spring. The leaves of Carolina jasmine are glossy, lance-shaped, and dark green in color.
Star jasmine, on the other hand, is also an evergreen vine but bears small, white, star-shaped flowers. These flowers have a sweet, intoxicating fragrance that is often used in perfumes. Star jasmine blooms during late spring or early summer. Its leaves are oval-shaped, glossy, and deep green in color.
3. Growth Habits:
Carolina jasmine is a vigorous grower and can reach heights of 20 to 30 feet. It requires support, such as a trellis or fence, to climb and thrive. This vine is often used to cover walls, fences, or pergolas, creating a beautiful green backdrop.
Star jasmine has a more compact growth habit, with a maximum height of 10 to 15 feet. It can be trained to climb or used as a ground cover. This vine is often seen cascading over walls or trellises, or used as a fragrant, low-growing hedge.
4. Hardiness:
Carolina jasmine is native to the southeastern United States and is well-adapted to a range of climates, from USDA hardiness zones 7 to 10. It can tolerate both heat and cold, making it a versatile choice for many gardeners.
Star jasmine is native to China and thrives in USDA hardiness zones 8 to 10. It prefers milder climates and may struggle in areas with harsh winters. In cooler regions, it can be grown in containers and brought indoors during the winter months.
5. Care and Maintenance:
Both Carolina jasmine and Star jasmine are relatively low-maintenance plants. They prefer well-draining soil and full sun to partial shade. Regular watering is essential during the establishment period, but once established, they are quite drought-tolerant.
Pruning is important for both vines to maintain their shape and control growth. Carolina jasmine should be pruned after flowering, while Star jasmine can be pruned in early spring to encourage bushier growth.
While Carolina jasmine and Star jasmine may share similarities in their appearance and growth habits, they are distinct plants. Carolina jasmine displays yellow flowers, has lance-shaped leaves, and can grow quite tall. Star jasmine, on the other hand, boasts fragrant white star-shaped flowers, oval leaves, and has a more compact growth habit. Understanding these differences can help gardeners choose the right vine for their specific needs and preferences.
