Lathyrus nissolia (Grass Vetchling) which is surprisingly a member of the pea family. The first photo shows a very young flower bud forming in the base of the leaf.
Myosotis discolor (Changing Forget-me-not). So called because the flowers change from a pale yellow to blue.
Orobanche minor (Common Broomrape)
And finally a Dingy Skipper, of which there were many enjoying the sun!
