Serendipity

I am by no means a great gardener, in fact, I am barely and adequate one. However, I do love pretty flowers, and when we moved into this flat the unpromising little plot in front of it set about producing buckets of the things with no input at all from me. Perfection!
I recognize most of them, but this yellow one flummoxes me. It's not in my one reference book...

These ones here are Michaelmas daisies:
These are wild peas:
And these are campanulas, whcih very obligingly come up in all the cracks and gaps in the stonework of the steps. Thanks to our weird weather this is their second flowering this year, making them excellent value!And of course, they provide an excellent opportunity to play with my new camera's close-up feature...
