I was strolling through a plant nursery and spotted a bush with pretty little purple clusters of flowers. I looked at the container and it showed Saint Duranta tree which I had never heard of.
I looked it up and found a site with some good info. Here is the link

Per the website, it is a shrub but it can grown up to 20 feet tall. The flower can be blue, purple or white. The plant grows fast and so it might be better away from walkways, because it will take over.
All I know is that it was lovely!
