Introduction
Star jasmine (Trachelospermum jasminoides) is a fragrant evergreen jasmine vine widely admired for its glossy foliage and star-shaped white blooms. Also known as confederate jasmine, this plant earned its common name from its popularity in the southern United States, where it thrives in warm climates. Although often grown as a climbing jasmine, it can also be shaped into an evergreen jasmine shrub. Gardeners love it for its sweet fragrance, vigorous climbing habit, and elegant appearance. In this guide, you’ll learn everything about planting, care, winter survival, toxicity concerns, common problems, and the many benefits of growing a versatile star jasmine plant.

The scientific name of star jasmine is Trachelospermum jasminoides.

- Jasmine trachelospermum

Is Star Jasmine a True Jasmine?
Star jasmine is not a true jasmine. True jasmine plants belong to the Jasminum genus. While both are fragrant and vining, a jasmine vine from the Jasminum group differs botanically from Trachelospermum jasminoides.
It is often called climbing jasmine because of its twining growth habit and sweet scent, which closely resembles traditional jasmine flowers.
Growth Habit & Appearance
Star jasmine vine can grow as either:
- A climbing vine with support
- A dense shrub form when regularly pruned
Star jasmine height and spread:

- Spread: 3–6 feet as ground cover
The white star jasmine vine produces small, pinwheel-shaped blooms in late spring to early summer. Star jasmine flowers release a strong, sweet fragrance, especially in warm evenings.
Star jasmine fruit is rare in cultivated gardens but may appear as slender seed pods in ideal conditions.
Available star jasmine colors are primarily white, though some varieties may develop creamy tones. When discussing star jasmine colours, white remains the dominant and most recognized bloom shade.
