This week’s WildflowerHour challenge was to find wildflowers, in bloom, growing on walls. You might think walls would be inhospitable places for plants to grow but it turns out that rather a lot of our British wildflowers relish life on a wall. It’s certainly a good place for a plant to find shelter, and a wall might also supply reflected or stored heat so, for those plants that are able to push their roots into tiny cracks and crevices and don’t mind a life of hanging around, a wall can be an ideal habitat.
Here are the wall-bound wildflowers I found during this week’s exercise walks: Daisy, Dandelion species, Forget-me-not, Groundsel, Herb Robert. Ivy-leaved toadflax (this seems to be growing in abundance on every local wall!), Red valerian, and, my favourite, Yellow corydalis.
