18 pretty pictures of nameless flowers

[SueA]

No.5 looks like Crocosmia 'Lucifer'.

[Palustris]

Just had another try,
Not sure I agree that 16 is White campion, it looks more like Saponaria officinalis alba plena, but maybe not.
14 Potentilla fruticosa alba may be either Vilmoriniana or P.f. mandschurica
To really id Hebes, you ned to be able to see a length of stem and the back and front of a leaf!
12Potentilla fruticosa again. Lots of named varieties.
6 Anemone japonica Honorine Jobert
5 Crocosmia (Montbretia is an invalid name, no longer in use).
Sorry it has taken so long.
