A seedling grows from a pod, loses its tag, and by its second summer nobody can say what it is. The leaves are long and narrow, the flowers look a bit like rubra, and the label that came with the seed says only plumeria. Questions like this are why a clear plumeria species list matters, and why the answer is not as simple as one name per plant.
This guide walks through the species currently accepted by Plants of the World Online, the botanical reference run by Kew. We cover where each species grows wild, what is documented about it, and which ones you will actually meet in gardens. We also explain how species differ from cultivars and hybrids, so you can read a plant label with confidence.
How many plumeria species are there?
The answer depends on who is counting. The Plants of the World Online database currently recognizes about 18 species, plus one natural hybrid. Other sources say 8, 11 or up to 20, so books and nursery sites often conflict.
The gap comes from history.
Linnaeus named only three plumeria species in 1753: rubra, alba and obtusa. Botanists later described well over 100 more names. Many rested on flower color or leaf shape alone.
Woodson’s 1938 revision folded many of them into a smaller group. Later work moved others into related genera such as Himatanthus.
That is why old names like Plumeria acutifolia still appear on tags and in older books. Today acutifolia is treated as a form of Plumeria rubra, not a separate species.
If you meet a rare name, check whether it is an accepted species or just a synonym. Do that before assuming you have something unusual.
The accepted plumeria species at a glance
The table follows the current accepted list. Native ranges are summarized and may change as botanists publish new work. For most of the Cuban and Hispaniolan species, detailed growth information is simply not well documented, and we say so rather than guess.
| Species | Native range | Habit and leaf (where documented) | Grown in gardens? |
|---|---|---|---|
| Plumeria rubra | Mexico through Central America to Colombia and Venezuela | Deciduous small tree, large leaves | Yes, the main garden species |
| Plumeria obtusa | Bahamas, Greater Antilles, southern Mexico, Belize, Guatemala, Florida | Evergreen or semi deciduous, blunt glossy leaves | Yes, widely |
| Plumeria alba | Puerto Rico and the Lesser Antilles | Narrow, corrugated leaves | Yes, less common |
| Plumeria pudica | Panama, Colombia, Venezuela | Evergreen, glossy spoon shaped leaves, blooms most of the year | Yes, popular |
| Plumeria inodora | Guyana, Colombia, Venezuela | Not well documented | Rare, if at all |
| Plumeria clusioides | Cuba | Not well documented | Rare, if at all |
| Plumeria cubensis | Cuba | Not well documented | Rare, if at all |
| Plumeria ekmanii | Cuba | Not well documented | Rare, if at all |
| Plumeria emarginata | Cuba | Not well documented | Rare, if at all |
| Plumeria filifolia | Cuba | Name suggests thread like leaves; little else documented | Rare, if at all |
| Plumeria lanata | Cuba | Not well documented | Rare, if at all |
| Plumeria montana | Cuba | Not well documented | Rare, if at all |
| Plumeria trinitensis | Cuba | Not well documented | Rare, if at all |
| Plumeria venosa | Cuba | Not well documented | Rare, if at all |
| Plumeria krugii | Puerto Rico | Not well documented | Rare, if at all |
| Plumeria magna | Hispaniola (Dominican Republic) | Not well documented | Rare, if at all |
| Plumeria subsessilis | Hispaniola | Not well documented | Rare, if at all |
| Plumeria tuberculata | Hispaniola; possibly Cuba, Bahamas and Jamaica | Not well documented | Rare, if at all |
Plumeria stenopetala, from Hispaniola, is listed as a natural hybrid rather than a species, so it is not counted in the 18. Some grower sources also use the name Plumeria stenophylla for a narrow leaved plant. We did not find it as a separate accepted species in the list we checked, so treat that name with care.
The four species gardeners actually grow
Almost every plant sold as a plumeria comes from just four species, and most of those come from one. Each has its own page on our site, so here is the short version.
Plumeria rubra
This is the type species and the parent of most named plants. It is a deciduous small tree with long leaves that drop in cool weather, and flowers in nearly every color. Our Plumeria rubra guide covers its traits and care in detail.
Plumeria obtusa
Often sold as Singapore or Singapore White, obtusa has blunt, glossy leaves and white flowers with yellow centers. It tends to hold its leaves through winter in mild climates, though it can go semi deciduous in the cold. Read more in our Plumeria obtusa profile.
Plumeria alba
Alba is notable for narrow leaves with a corrugated texture and white blooms. It is less common in nurseries than rubra or obtusa. We cover it on the Plumeria alba page.
Plumeria pudica
Pudica is a tall, narrow evergreen with glossy, spoon shaped leaves. Its white flowers appear for much of the year, which is why it is prized for its long season. See the Plumeria pudica guide for growing details.
Species, cultivars and hybrids: what is the difference?
A species is a wild kind of plant that breeds true across a natural range. A cultivar is a named plant selected and kept alive by cuttings or grafts, such as a particular pink flowered tree with a registered name. A hybrid comes from crossing two plants, whether by nature or by a breeder.
Hundreds of named plumeria are cultivars, and most trace back to rubra, often with some obtusa blood. Our guide to plumeria varieties sorts the named plants by color, origin and bloom type, so we will not repeat that list here.
Seed adds another layer. Seedlings from a cultivar usually do not match the parent, because flowers cross with whatever pollen is nearby. That is how unlabeled plants like the lost tag tree above appear.
It is also a main reason growers reach for cuttings. Our seed growing guide explains what to expect.
Why identifying a plumeria species is hard
Growers naming an unlabeled tree compare leaf shape, petal width, scent and winter behavior. The problem is that these traits overlap, and hybrids blur the lines further. A narrow leaved tree with broad petals might be a species, a cross, or a seedling of a named plant.
A few practical clues help, though they are not proof:
- Large, deciduous leaves that fall in winter point toward rubra types.
- Blunt, glossy leaves that stay on through mild winters suggest obtusa.
- Tall, narrow growth with spoon shaped leaves and near constant white flowers suggests pudica.
- Narrow, corrugated leaves suggest alba.
Only a botanist can settle a hard case, using flowers, fruit and leaf detail. For a garden plant, the useful question is usually how it behaves, not what it is called.
Plumeria species and cold tolerance
Every accepted species comes from the tropical Americas, so none of them is truly cold hardy. Differences between species are real but modest, and growers disagree about exact limits. Our guide on plumeria cold hardiness gives the ranges and explains where sources conflict.
If you are curious how the common name relates to the botanical one, see plumeria vs frangipani. All species share the same milky sap, which can irritate skin.

Frequently Asked Questions
How many species of plumeria are there?
Plants of the World Online lists about 18 accepted species and one natural hybrid. Older books and nursery sites give lower or higher numbers because of past disagreements over which names are real species.
Is Plumeria acutifolia a separate species?
No. Acutifolia is now treated as a form of Plumeria rubra. You will still see the name on older tags and in older books.
Which plumeria species is best for beginners?
Most beginners end up with a rubra cultivar, since those are the most widely sold. Obtusa and pudica are also common and tend to keep their leaves longer in mild climates.
Are plumeria hybrids the same as cultivars?
Not always. A hybrid is defined by its parentage, while a cultivar is a named plant kept going by cuttings. Many cultivars are hybrids, but some are simply selected forms of one species.
Can I tell the species from the flowers alone?
Rarely with confidence. Flower color varies widely within rubra, and hybrids blur the differences, so leaves and growth habit help more than petals.
