Ooh!
We get something quite similar!
Really teeny-tiny things compared to garden centre bought pansies or even violas. At school we called them forget-me-nots. But at the age I'm talking about, one person would say something with conviction and the rest of us took it as gospel. They grew all over the school playing field for about 5 days every Spring anyway.
ETA - I think what you have are
violas, and I hazard a guess they're
Viola riviniana or the common dog violet. I'm still searching for the ones I was talking about.
