In The Garden: Fern Identification Help?

I have ferns in pots on my deck, and there are two plants of a sort I like but cannot identify.

I would like to buy more of these, but do not know what they are or where to buy.

Any help will be greatly appreciated.

 

Athyrium filix-femina corymbiferum?

 

Thank you so much for your prompt and helpful reply!

You fairly surely have correctly identified what I have.

Much appreciated.

Not a Dryopteris?

 

Athyrium filix-femina corymbiferum seems to be a better fit, from the photos I could find on the internet.

the photo at http://www.gardeninginfozone.com/best-outdoor-and-garden-ferns seems to be very like what I have.

Thanks for your interest.
