Thanks Buttercup. I think 3 might be a wait and see. I have oenothera in number but the don't look like that and they're nowhere near flowering.
I appreciate all the suggestions.
I've only just got round to checking out Pere David and he'e a flexuosa hybrid. I don't think this is a flexuosa, not blue enough
