I apologize for the sorry description. I'm posting for my mother. She's good at growing flowers but not so good at using the Net. I've attached a photo. Thanks! ( photo / image / picture from wordbuilder's Garden )
It is difficult for me to make out...but I think that the small purple ones may be one of the Nepeta sorts. I can´t see any of the leaves very well. It should have a scent if you rub the leaves a bit roughly between thumb and forefinger.
I spoke to my mom. You're right on the purple ones. They do have a smell. Turns out, they are catmint. Thanks! I've uploaded a larger shot of just the pink flowers. ( photo / image / picture from wordbuilder's Garden )
