For some reason it is not letting me upload a pic so I will just include the link. It is the top picture.

Actually, if you are looking at the large "flat" flower at the left, it is an orchid--a phalaenopsis, or moth orchid. They are exquisite and a popular wedding flower. They come in a number of colors and if you Google moth orchid you can see the variety.
There are cutters and veiners available in many of the cake supply sites.
Good luck.

It does say roses, but maybe the person who wrote the caption got it wrong. I agree that they look more like gardenias.
If you are refering to the first cake with only 4 flowers on it those look like all white poeny...if this link works (never att. one here befor) here is a pic of a pink one.

They look like double wild roses to me. Check the link.

I too think they look like double wild roses 
we have some growing in our garden and are quite beautiful
Tree peonies & double & single petal shrub peonies, usually have visible stamens, and there isn't any stamens on the cake flowers that I could see. Most peonies tend to have ruffled petals also whereas the flower petals on the cake are more rounded.
They might be double gardenia's but I still think they look more like wild white roses. I'd just call or email the customer to confirm she meant roses. It would save you a lot of wondering!
I agree with warchild!! Email her and attach photos of her choices and then have HER decide. It will save you the heartache if she is expecting gardenias and you give her large roses. Especially since obviously everyone that sees them thinks they are a different variety, as even on here we have 3 or 4 different opinions. But if you ask her what SHE sees, then you can give her what she actually wants.
