Bellis perennis is a common European species of daisies, and often considered the archetypal species of that name. Bellis (Latin) means beautiful, pretty, perennis (Latin) persistent, perennial. This species is spread by contaminated grass seeds all over the world. You can find it in North and South America, along the Pacific coast, in Madeira and New Zealand.
A beautiful dreamy shot M. I wonder if these flowers are currently blooming in your area or did you happened to bring one along with you for this shot? It's great to see your lake in the background with the people as well. :)
