- Rose petals for a 'Rosolio' and violets for 'Parfait Amour' were
mentioned earlier. The 'Parfait Amour' is colored blue. I looked up
my herb book and found that 'Cornflower' flowers (Centaurea cyanus)
and the stems and leaves of 'Meadowsweet' (Filipendula ulmaria) will
give a natural blue color. I gather then that violets themselves will
not, and steeping for 5 minutes is sufficient for flavoring purposes.
Meadowsweet roots will also give black, while the tops a green-yellow.
Other aromatic flowers mentioned in recipes are jasmine, orange
blossom, elderflower, rosemary flowers, and lavender flowers. About
11/2 cups of flowers for 11/2 cups alcohol seems to be the norm.
