As you can see I am also a brit. Peat bogs are conspicuous by their absence though.
At this time of year they shouldn't be flowering. However, if they are then you can use the flowers in salads or omelettes.
Honey, pinch the flowers off. I've grown mint for years indoors and out. It will go to sleep in winter and come back up as the weather warms up. It is the hardiest of herbs.
