I'm not sure what this is either. It is growing in the planter outside my doctor's office, and I liked the purple, so I took a picture of it. Doesn't have a fragrance but it had a lot of these purple flowers.
September 2015 - I dropped my Nikon L22 at the arboretum (on asphalt!) and it's definitely broken. :(
October 2014- finally reached 365 photographs and it...
@sana@sailingmusic Thank you very much! The last time I was over there it did have a couple of bumblebees hanging around it, now you mention it. But it has these bright purple flowers that just pop with color.
