A Field Guide to the True Jasmines
On real jasmine, its many pretenders, and how to fill a Southern summer evening with the most famous fragrance in the world.

I.What jasmine actually is
Say the word jasmine and almost everyone conjures the same thing: a warm night, a white star of a flower, a scent that seems to arrive before you find its source. What most people do not know is how loosely that word gets thrown around. True jasmine is a specific thing, a genus of some two hundred species called Jasminum, and it belongs, of all places, to the olive family, the Oleaceae. Its home ground runs across the warm temperate and tropical stretches of Asia, Africa, and Oceania, with its center of gravity in South and Southeast Asia.
These are shrubs and twining vines, most of them fragrant, a few of them not, and their diversity is far greater than the single perfumed climber of the popular imagination. Some bloom in the dead of winter on bare stems. Some are red. Some are hardy well up into the middle South, and a few will not tolerate a frost at all. Learning to tell them apart is one of the small, durable pleasures of gardening in a warm climate.
True jasmine is a member of the olive family, two hundred species deep, and only a fraction of what gets sold under the name is the real article.
II.The imposters (and why it matters)
Half the plants sold as "jasmine" in the South are not jasmine at all. This is not pedantry. The pretenders behave differently, want different things, and in one notable case will poison you, so it pays to know who is who before you plant against your front porch.
Field Note: Three Famous Fakes
Confederate or star jasmine is Trachelospermum jasminoides, a lovely and useful vine, but a member of the dogbane family (Apocynaceae), not a jasmine. Carolina jasmine (also yellow or false jasmine) is Gelsemium sempervirens, our state flower's cousin in spirit, from yet another family entirely, and every part of it is toxic. Night-blooming jasmine is usually a Cestrum, a relative of the nightshade. All three are worth growing on their own terms. None of them is Jasminum.
Why care? Because when a gardener tells us "my jasmine died in the shade" or "my jasmine never smells," the fix usually starts with figuring out which plant they actually have. A true Jasminum wants sun and warmth and rewards it with scent. A Confederate jasmine tolerates more shade. A winter jasmine offers no fragrance at all and never promised any. Names carry expectations, and mismatched expectations are where most garden disappointments begin.
III.The jasmines we grow
Here is the working collection, the true Jasminum we propagate and grow at the nursery, arranged more or less from the classics to the curiosities.
Common, Poet's, or True Jasmine (Jasminum officinale)
- Vine
- Fragrant
- Hardy to Zone 7
- Summer-long bloom
If you grow one jasmine, grow this one. The poet's jasmine is the hardy backbone of the genus, a vigorous twining vine that carries clusters of pure white stars from a big late-spring flush straight through summer until frost. The fragrance is the real thing, the one the poets meant, strong enough that a single well-placed vine can perfume an entire courtyard on a still evening. Hardy to roughly Zone 7, which puts it comfortably in reach of most Southern gardens.
Shop Jasminum officinale →Spanish or Royal Jasmine (Jasminum officinale var. grandiflorum)
- Vine
- Fragrant
- Medicinal
- Perfumer's jasmine
The large-flowered, intensely scented form that perfume is built on. This is the jasmine of tradition and of the great fragrance houses, with bigger blooms and a deeper, headier scent than the type. Grow it where you can lean in.
Shop Spanish jasmine →Red Jasmine (Jasminum beesianum)
- Vine
- Fragrant
- Very Rare
- Unusual color
The rule-breaker. In a genus defined by white and yellow, Bee's jasmine flowers in soft, unexpected shades of pinkish red, a color that stops people mid-sentence. Vigorous and semi-evergreen, it is one of the more collectible plants we offer, and one of the few chances a Southern gardener has to grow a jasmine that is not white.
Shop red jasmine →Pink or Chinese Jasmine (Jasminum polyanthum)
- Vine
- Fragrant
- Tender (Zones 8–11)
- Floriferous
The most generous bloomer of the group, an evergreen twiner that smothers itself in reddish-pink buds opening to fragrant white stars in late winter and early spring. It resents hard freezes, so in the colder parts of our range it earns its keep on a warm wall, a sheltered porch, or in a pot that comes indoors. Where it is happy, it is unforgettable.
Shop pink jasmine →Stephan Jasmine (Jasminum × stephanense)
- Vine
- Fragrant
- Very Rare
- Pink hybrid
A rare pink-flowered hybrid between the red jasmine and the poet's jasmine, blending the unusual color of one parent with the hardiness and scent of the other. Soft rose blooms, a light sweet fragrance, and a pedigree that makes it a quiet prize for the collector.
Shop the Stephan jasmine →Golden Jasmine (Jasminum officinale 'Fiona Sunrise')
- Vine
- Fragrant
- Gold foliage
- New
A poet's jasmine with a costume change: the same fragrant white flowers and hardy constitution, dressed in bright chartreuse-gold foliage that glows against a dark fence or wall. Two ornamental jobs from one plant, scent and season-long color, which is our favorite kind of value.
Shop 'Fiona Sunrise' →Winter Jasmine (Jasminum nudiflorum)
- Scrambling shrub
- Not fragrant
- Zones 6–10
- Late-winter yellow
The contrarian of the genus, and a plant we love for exactly that. Winter jasmine is a deciduous, scrambling shrub from western China that opens bright yellow flowers on bare green stems in the depth of winter, weeks before anything else stirs. The catch, and it is a fair one to state plainly, is that the flowers carry no scent. You grow this one for color in the cold months and for its willingness to cascade over a wall or bank, not for perfume.

V.Growing jasmine in the South
The true jasmines ask for less than their reputation suggests. Give the vining species sun to light shade, the more sun the more flowers and scent, and a support to climb: a trellis, an arbor, a length of wire along a fence, or the porch post itself. They are not fussy about soil so long as it drains, and they appreciate a summer drink in a dry spell but dislike sitting wet.
Prune right after the main flush of bloom, which keeps the plant tidy without sacrificing next season's flowers. For the tender ones, chiefly pink jasmine, the whole game is winter placement: a warm microclimate, a sheltered wall, or a pot that can duck indoors when the forecast turns hard. In the Aiken area and points south, the hardy vines settle in as permanent residents; in the coldest corners of the range, treat the tender species as the seasonal luxuries they are.
Field Note: Siting for Scent
Fragrance is a design material, and jasmine is the most generous supplier of it we know. Plant a poet's jasmine where warm air pools and lingers in the evening: beside a seating area, under a bedroom window, along the path you walk after dark. Scent rises and drifts on warm air, so a vine trained just above head height on an arbor will greet you as you pass beneath. This is the difference between owning a jasmine and living with one.
VI.The scent that built an industry
No flower has done more for perfume. The absolute distilled from Spanish jasmine is one of the foundational notes of the entire fragrance trade, prized because it cannot be convincingly faked and costly because it must be gathered by hand, at night, when the flowers give up the most of themselves. In garden after garden across the warm world, jasmine has earned nicknames that all circle the same idea: the flower is at its most eloquent after sundown.
Jasmine is a night speaker. It saves its best sentence for the hour after the sun goes down, which is, not coincidentally, the hour a Southern gardener finally sits down.
There is something fitting in that for us. A Southern summer is largely an evening proposition. The heat pushes the good hours to either end of the day, and it is on the porch after dinner, when the light goes long and gold and then blue, that a garden earns its keep. A jasmine trained where that air moves is not decoration. It is the reason to be out there.
VII.Common questions
Which jasmine is the most fragrant and the easiest for a Southern garden?
For most gardeners in our range, Jasminum officinale, the poet's jasmine, is the sweet spot: reliably hardy to about Zone 7, strongly scented, and blooming for months. The Spanish jasmine (J. officinale var. grandiflorum) is even more intensely fragrant if you want to lean into scent.
Why doesn't my jasmine smell like anything?
Two likely reasons. Either you are growing winter jasmine (J. nudiflorum), which is genuinely unscented, or you are growing a Confederate or Carolina jasmine, which are not true jasmines at all. A true summer Jasminum in enough sun should perfume the air readily.
Can I grow the tender ones, like pink jasmine, where it freezes?
Yes, with a plan. Pink jasmine (J. polyanthum) thrives on a warm sheltered wall in the lower South and makes a superb container plant elsewhere, blooming in late winter indoors and summering outside. Think of it as a movable luxury rather than a permanent fixture.
Is any true jasmine toxic?
The true jasmines (Jasminum) are not considered dangerously toxic. The caution is reserved for the imposters, particularly Carolina jasmine (Gelsemium sempervirens), which is genuinely poisonous in all its parts. One more reason to know which plant you actually have.
From the Nursery
We propagate and grow the true jasmines here in Aiken, from the dependable poet's jasmine and the perfumer's Spanish jasmine to the uncommon red jasmine, the floriferous pink jasmine, the rare Stephan hybrid, the gold-leaved 'Fiona Sunrise', and the cheerfully scentless winter jasmine. Several are rare enough that stock comes and goes, so if one is between restocks it is worth checking back. If you are trying to choose the right jasmine for a particular wall or porch, we are always happy to help you match the plant to the spot.
