Garden flowers

While doing a bit of gardening today I took some photos of the flowers.


I don't think I'd noticed before the spiralling of the parts (stamens?) of the daisy which carry the yellow pollen.


Looking at my "Complete British Wildlife" I think I've identified the next one as greater celandine.


This looks like it could be willowherb, but it shouldn't be out until July, so perhaps it isn't.


The next photo isn't of a flower as such, but can you tell what it is?



Update on conservatory: My temporary flood prevention measures have been soak tested today. All dry inside so far!
