Pink Jasmine: The Fragrant, Fast-Growing Winter Vine
By Richard Flowers, ACCNP, Green Thumb Nursery, Ventura
When people think of fragrance, jasmine is one of the first plants that comes to mind, and for good reason. Every year in late winter I watch the pink buds appear just outside my kitchen window, and when they open to sweet white flowers I cut a few runners to drape over my bedroom window so the perfume drifts inside for days. That plant is pink jasmine, and it is one of the most rewarding fragrant vines you can grow in Southern California.
Quick answer: Pink jasmine (Jasminum polyanthum) is a fast-growing, evergreen twining vine prized for its intensely sweet fragrance. In late winter and early spring it covers itself in flowers that are pink in bud and open to white, star-shaped blooms. It grows in full sun to part shade, is hardy to about USDA zone 8, climbs 15 to 20 feet with support (or sprawls as a groundcover), and takes well to pruning, so you can keep it to any size. In Southern California it is easy to grow, deer-resistant, and happy on a fence, arbor, wall trellis, or around a doorway where the scent can drift indoors.
What Is Pink Jasmine?
Pink jasmine is known botanically as Jasminum polyanthum, and it belongs to the olive family, Oleaceae, alongside olives, forsythia, lilac, ash trees, and privet (NC State Extension). It is native to western China, in the Guizhou, Sichuan, and Yunnan provinces (Oregon State University). The genus name comes from the Persian word yasameen, and the species name polyanthum combines the Greek for “many” and “flowers,” a fitting description for a vine that blooms by the hundreds. Its leaves are compound, with several small leaflets to a stem, which gives the whole vine a soft, lacy, delicate look.
Pink Jasmine Flowers and Fragrance
The flowers are the whole point. They are white on the inside and pink to rose on the outside, star-shaped with five petals, about 2 centimeters across, and borne in dense clusters all over the vine. More than the look, it is the scent people fall for: pink jasmine is very fragrant, and on a still evening the perfume carries well beyond the plant (Oregon State University). It blooms heaviest in late winter and into spring, and in mild coastal areas it tends to flower a little earlier, sometimes with scattered blooms at other times of year. That early, generous bloom is exactly why it is such a welcome sight at the tail end of winter.
How Fast Does Pink Jasmine Grow, and How Big?
Pink jasmine is a fast, vigorous grower that can reach about 20 feet with support (Oregon State University). It climbs by twining, weaving its stems in and out of a fence or trellis, and wherever a stem touches the soil it can root and spread as a groundcover. It is vigorous enough that in frost-free, tropical climates it can become weedy, though it is not listed as an invasive plant in California (Cal-IPC). The practical takeaway is simple: give it a sturdy support and prune it to keep it where you want it. Left alone it will happily cover a fence, climb 15 feet or more into a tree, and fill in any bare ground beneath. Kept trimmed, it makes a tidy, lacy screen at 8 to 9 feet on an arbor.
How to Grow and Care for Pink Jasmine
Pink jasmine is easy to grow and adapts to a wide range of Southern California conditions, from hot interior valleys to cooler coastal gardens. It blooms most abundantly in full sun but flowers satisfactorily in part shade (NC State Extension). It is hardy to about USDA zone 8 and may want a little protection from a hard frost, but it is tolerant and comes back strong. It grows faster in good soil but adapts to less than perfect conditions, and it is deer-resistant. Use it to dress up an old fence, cover a wall on a grid trellis, frame a door or window so the fragrance wafts inside, or grow it in a large container or hanging basket.

Pruning Pink Jasmine
The best time to prune is right after the vine finishes blooming, which also sets up a good round of buds for next year (NC State Extension). Over the years, older plants build up woody stems and dead thatch that start to look untidy. In my own garden, every three to four years I cut the whole vine back hard, almost to the ground, once it has finished flowering, and clear out all the dead debris. The following spring it comes back fresh and clean and quickly covers the fence again. If you would rather not do a hard reset, simply pinch and prune through the year to control the size.
Frequently Asked Questions
Is pink jasmine fragrant?
Very. Pink jasmine is one of the most intensely fragrant vines you can grow, with a sweet perfume that carries on the breeze, which is why it is so often planted near a window, door, or patio.
How fast does pink jasmine grow?
Fast. Pink jasmine is a vigorous grower that can reach 15 to 20 feet with support, so give it a sturdy trellis, fence, or arbor and plan to prune it to keep it in bounds.
When does pink jasmine bloom?
Mainly in late winter and into spring, with the heaviest, most fragrant flush then. In mild coastal areas it may bloom a little earlier and send out scattered flowers at other times.
Does pink jasmine need full sun?
It blooms most heavily in full sun, but it also grows and flowers satisfactorily in part shade. For the biggest show of fragrant flowers, give it as much sun as you can.
Is pink jasmine evergreen?
Yes. In the mild Southern California climate pink jasmine is an evergreen vine, holding its lacy green foliage through the year.
How do you prune pink jasmine?
Prune right after it finishes blooming. Pinch and trim through the year to control its size, and every few years cut an old, woody plant back hard and clear out the dead growth so it returns fresh.
Is pink jasmine toxic?
Pink jasmine is a true jasmine grown as an ornamental, and the ASPCA lists plants in the genus Jasminum as non-toxic to dogs, cats, and horses. It is not a culinary herb, so enjoy it for its flowers and fragrance rather than for eating. One note on names: several unrelated and toxic plants are also called “jasmine,” such as Carolina jessamine (Gelsemium), so make sure what you have is a true Jasminum.

Pink jasmine really is a wonderful addition to a garden, as happy cloaking a bare fence as it is perfuming a doorway. Come by your favorite Green Thumb Nursery location and check out pink jasmine and other fragrant vines. If you want evergreen privacy without the strong scent, take a look at its cousin star jasmine too (which, despite the name, is not a true jasmine), and see our guide to climbing plants that cover a fence or wall.
