I've been picking and admiring bergamot for years. I usually eat the flowers as soon as they bloom in the summer. (the soft petal part not the hard spiky ball part) I'll pinch the flowers, pull them off and then eat them from the bottom up. little kids seem to really get a kick out of eating flowers

.
I've often wondered if the leaves or the flowers are better for tea but, I never seem to be able to remember to dry any flowers.
I've also noticed that the flower head (hard spiky ball part that has all of the seeds in it) will smell strongly of bergamot for several years after I pick it.
