No 2 is Mecanopsis and No 3 is Lewisia. Sorry I don't know No 1 but I'm sure the more knowledgeable will enlighten you :)

Agree with Scottish for 2+3, 1 may be dogs tooth violet (erythronium)

1 Erethronium possibly 'pagoda'
2 Mecanopsis x sheldonii the blue poppy : not a true poppy
3 Lewisia cotelyedon

All very nice plants. :o)

Agree with SBG

SBG's written what I was going to put! :-) Except that I'm certain that No. 1 is Erythonium 'Pagoda'

Thanks everyone.

oops my spelling's getting worse Beattie :o)
