I was going to title this 'Random plant' because my computer has started backing itself up, so it's grinding to a halt and searching for a name sends Explorer into shock mode. Its flowers are like hemlock but I'm pretty sure it isn't that. Anyway - it isn't random - its flowers are very carefully arranged and I'm sure if I look properly Fibonacci sequence will be involved.
I have just been looking up to find out what this is called the one it looks like most is Oenathe Pimpielloides... Corky-fruited Water Dropwort butits a job to tell so many look alike and I can not see the leaves very clearly. lovely picture
Did you lie on the ground for this shot ? I love the way you have the flowers against the sky like that ,it really shows them off so well ! We have these flowers down our lane in the banks but I don't know their proper name either !
