It's a whole lil place in there. You could kick back on an anther and still have plenty of room for company.
I made simple syrup with the flowers and used it for a color-changing Tom Collins. The pigment of the flowers reacts with acid and changes from dark purple/blue to bright pink. It has a nice flavor too though it's pretty subtle.
Interesting, didn't know you could use them in syrup! Do you put them in cold or steep them after you take it off the heat?
I put about an ounce of them in a half pint mason jar with two ounces of water + two ounces of sugar and microwaved it until right when it started to boil. Let it sit overnight and then shook it up the next day and that's when most of the color dropped out.
From reading a few different recipes online I'm guessing if you had a larger amount and simmered it on low heat for ten minutes or so you wouldn't need to let them soak for as long.
