I haven't identified it yet, but there are dozens of fonts in this style if an exact match isn’t important:
La Veronique
Harlean
Azalea Rough
Azalea Smooth
Adorn Bouquet
Caprizant
Lovingly Friends Script
Allegreto Script
Blingtastic
Botanica Script
Goodlife Brush
Voluta Script
Aphrosine
Adorn Pomander
Depending on the project, I’d also strongly recommend hiring a calligrapher. For many purposes it is worth the investment, and it will result in a more customized style that specifically suits your needs.
