Wild Carrot has to be my favourite Umbellifer plant, especially at this time of year, when many of the inflorescences are going to seed. These plants are in Edinburgh's Comely Bank Cemetery
I love the way that the inflorescence folds up once it's gone to seed
In the centre of most inflorescences of this plant, there is a red flower, which you can see in the photo below. The red flower is just to the right of the Batman hoverfly (Myathropa florea) which seems to have a particular liking for Wild Carrot.
