Corydalis flexuosa

Good photo! Those flowers look like heads of Alien, lol.

They are very unusual have to say:)

Lovely...not seen these before.very delicate looking!

Love this one, yours is way ahead of mine. :o)

Very nice Kasy, way ahead of mine too. :-)

How big are these? Are they hard to grow? I didn´t see any at all here.

I keep mine in a sheltered corner near the kitchen door. Seems like not so hardy plants like it there, and hardy once are bit ahead of others too.
Katarina - it is small plant - height 0.3m; spread 0.5 m -deciduous perennial, it likes partial shade. Fully hardy so it should be ok where you live:)

very beautiful, love the colour

Thank you Sticki:)
