It could be, we need more information. There are a few roses that look similar, Blue Girl, Lady X.
No thorns at all smooth canes foliage is mid green and matt not glossy. Very mild almost no tea fragrance. Blooms one on a stem.
looks like stainless steel
blue girl is fragrant.
Lady X is fragrant too. Maybe Stainless Steel. Would need to see photo of not-so-open bloom.
There are two Blue Girls--Kordes and Tantau. One is fragrant and the other isn't. Mine isn't and doesn't look anything like this one. Check out HelpMeFind.com for assistance.
Could it be Lagerfeld?
