Yes I have some growing in a pot, bought at a National Trust property several weeks ago. It smelt very strongly of chocolate and mint at the time, but now its grown larger it seems to have lost the chocolate smell.
yes keep it well trimmed don't cook with it but put the sprigs in little vases on a sunny window sill they make a different air freshener..
Best air freshener mint is the one that smells of Eau de Cologne Water mint is also lovely
