We think vic's photo is in the wrong place Sue.
The upper leaves on my Nepeta cataria citriodora as posted above are quite pointed on the tip, I have a photo of the same plant when it was growing in a pot when it was without the flower spike, the leaves are more rounded on the basal leaves.
I have Agastache, an aniseed scented one and a peppermint one that keep setting around, both have a very strong smell. If we could get a better idea of the type of scent the leaves have it would help but flowers help more. Some Agastache leaves do look much like Nepeta cataria.
