Perennial Wallflowers

We noticed these tiny flowers coming out about 3 years ago. We'd planted them at the steps but they were swamped by other plants such as the periwinkle. Year by year, they have come back stronger and stronger until we have this beautiful display. Tiny but obviously very hardy and taking no nonsense from the bigger plants!
This plant is along the fence but the one by the steps has shown the same resilience.
The other contender for todays blip, Lonely Cloud, is in the Extra box but I liked the flowers.
