It looks possibly like some variety of plumeria

Wow, it's gorgeous. I would guess a relative of plumeria also. Is it a vine? It could be Chonemorpha penangensis or Stemmadenia galeottiana (litoralis), Milky Way tree, which are both in the Apocynaceae family. I think it might be Stemmadenia.

The flowers don't look quite like the flowers on a chonemorpha and a chonemorpha vines, doesn't look like that is vining would be much easier to tell if they were open. It's definitely a member of the apocynaceae family. I think clare is spot on with the stemmadenia littoralis.

Lucky you, yes it's a stemmadenia.
It's my favorite tree in the garden.
Where I live here in Florida, they bloom 8-10 months of the year........cheryl

RisingPower, Clare and Cheryl, THANKS to you all.

It looks like a great small tree and I will plant it very close to my house. I just found out that none of Stemmadenia sp. is endemic to Thailand (according to my reference books). Thanks again.

Here is a picture of one of my stemmadenia trees this past summer.
It's fragrant day and night........cheryl

Cheryl, This is really a lovely and healthy tree. Thanks for the photo. I am so excited....well, I already planted mine this morning.

Congrats, Kukiat, on acquiring such a beautiful tree. I'm glad we could help.

Cheryl, your tree is gorgeous! I've got to get one of those.

Cheryl,

Stemmadenia has got to be no. 1 on my "I really want it but don't have space for it in winter" list! Great growing!

Jim

Jim, I kept one in a -5 gallon pot for over 2 years.
It never got more than 6-7 foot tall.
It also bloomed almost as heavy as the ones planted.
The man I bought my 1st one off of said "zone 10 - no weather under 40 degrees".
go down to 32 3-4 times in the winter months.
Well, we've had several 32dregee nights here St.Petersburg
and only miner leaf damage occurred to mine.
If it were me, I'd find the space to have it.
It is my #1 tree!.......cheryl

Cheryl -- your name seems to rhyme with "enable!"

Thnx! It may go down on my spring Gardino order!

Jim

Cheryl are you saying people like Jim and I who live where the snow flies could keep this in a container and move it in and out as the seasons change and still get it to bloom and be fragrant? The picture and description of yours makes my heart go pitter patter!

Sweet B, I don't see why you can't.
As soon as temps hit 70 here,
my Stemmadenia starts budding up and blooming
and cont. blooms until the temps drop below 70 in the fall.
I think if you give it as much sun as you can(full sun in the summertime)
and give a good 3-6 month fertilizer,
you shouldn't have any problem getting it to grow and bloom.
Just be careful not to leave it outside when temps go below 40.......cheryl

Hi everybody,
I long waited for my tropical vines to bloom , and now that they flowered, both chonemorpha penagensis and hiptage benghalensis flowers ( plenty of them) have no fragrance at all. What is happening? Please help an old fan of fragrant plants not to despair...
