Ah, the wonders of photography that allows us to look at the details in nature at leisure.
This is a ceanothus, otherwise known as the California lilac – and a close up of the flower.
Lilac is an Old World species – quite common in the UK in parks and gardens – and I guess that whoever named the California lilac had it in mind, although the species look very different from one another.
The second photo is of comfrey. It has an interesting history as a folk medicine and in the last thirty or forty years or so has had a renaissance as a plant that helps other plants to ward off pests.
