Here are some photos. This one is planted in a median strip. My partner likes it and would like to put some in our garden.
There are four pictures where it says “Recent Activity”. The plant we’re interested in is the one with purple flowers, not the spiky one.
My description would be: small silvery-green leaves several layers thick around the base of a long skinny stalk that is topped with a small purple bowl-shaped flower with a single layer of petals. I am no botanist, but the leaves make me think it might be a succulent of some kind.
