Ferns.

Those look like young fronds of the Ostrich Fern were they taken a while ago

These were taken in May at Arboretum Tesarske Mlynany, on which I made a blog, too. So this is Ostrich Fern? That is its name? Thank you! :)

If you want the proper name it is < Matteucia Struthiopteris >

A nice grouping there !

they look good altogether.

kind of remind me of shuttlecocks - I love the shape of ferns -

Paulsgarden@bingo! Yes, they look like that :)
Bjs@ Thank you for its proper classification :).
