Does it smell like chocolate when you bruise the foliage? If so it's chocolate mint. If not, its not ;-)

FYI - Scents are often weak in the spring when they are very flush with water.

That's true. I wasn't really considering the time of year. But what other techniques are there if one's not an expert, since so many mints look similar?

I now believe them to be orange mint. Saw them in a local nursery.

There difference type varieties and species mint

If you smells:

Smells like orange then Orange Mint

Smells like chocolate then Chocolate Mint

Smells like toothpaste and stonger then it's Peppermint

Smells like gum and less stonger than Spearmint
