I have to laugh at myself at the grocery store when I'm buying flat leaf parsley. I have to stare at it and sniff it for a few seconds to make sure that it isn't cilantro...every single time. And the sad thing is that I probably buy parsley at least once a week.
Which is why I love this "vintage" idea from Martha Stewart.
Simply paint the name of each herb in your garden on to individual terracotta pots. It looks more elegant than the plastic nametags of norm. And it will prevent me from clipping my cilantro...when 9 times out of 10 I need the parsley.
