I purchased a Star Jasmine and a Royal Jasmine two years ago. They bloom all the time and they look identical with the exception of the leaves. I have been trying to find out if Hirt or Logee mis labeled them. Both have identical flowers and both flowers have the same fragrance.
I have been discussing these plants with a customer of mine who works at the Atlanta Botanical Gardens and he sent me this information.
Royal jasmine (Jasminum rex) has a completely different petal shape and the flowers are the largest in the jasmine family, it is hard to find...it is also scentless.
Star jasmine (Jasminum multiflorum) has a similiar flower to the nitidum but the buds should not be pink and should be forn in an umbel shape inflorescence.
He suggested there was a mixup in the labeling at the places I purchased them.

I see a definite difference in the leaves, but my mystery is that the flowers on both plants smell identical. Yet, the Royal is to be scentless.

Here is a picture of the so called Royal jasminum nitidum that I have.



Now the Star jasminum nitidum

The first picture is too fuzzy for me to tell.

Come on Amanda, it ain't that bad.................groan and moan. O.K. you win, I will see if the other one is any better.
You look like an sweet darling angelic person opn your picture. Now I know why I adore you.
This one is marked Royal Jasminun

I am having problems with my computer and many times a post will print twice. I apologize if that happens and I do not catch it in time to delete the dupllicate.

Amanda, I took those with my cell phone and I apologize, they both seem a bit fuzzy. I am sorry.
Guess I can not expect much help using these pic tures.

JB...looking at pics of Jasminum rex the flowers have more rounded petals than the ones in your pic, which I'd describe as long, slender(er), some lanceolate petals.

I wonder if you have two species of Star Jasmine and the slight difference in the leaves could be due to age or perhaps it crossed with something, eh?

Just guessing here. Especially since J. rex isn't supposed to have a fragrance.

Or did you ever come to a conclusion to this, since I now notice it was posted last month?

Shoe, thanks for the belated comments.

I think they were mismarked at the distributor. The leaves color difference is a mystery, but then, many things I get from Hirt have a discolored leaf. I think they use some sort of spray that does that. i do appreciate you thoughts, even it I could have died of old age before you got around to it.

Hope your Aimee is doing o.k. The cuttings I got from Linda of the radicans are not doing well in water. They are long cuttings compared to what I usually take and maybe I should have put them in a medium instead. What do you think?

Hah! Naww, you ain't dying anytime soon! I just now stumbled across your thread and it caught my eye...

Yep, Aimee is doing well. Getting cooler nights here so am hoping to move things into the g-house soon (which is a weed jungle and needs cleaning first!)

I just stuck some cuttings of Radicans last week or so. I ended up seeing one marked down at Lowes or Home Depot and needed new stock so bought it because it had enough new growth on it to take cuttings. They're all fairly short cuttings but I put them in soil/medium. I think soil rooting goes much faster than water for certain cuttings. I'll also put them on a heat mat with minimal temp just to keep the soil at an even temperature.

If yours don't make it I'll send you something in the spring.

Best!
