Does anyone know the northernmost limit to grow these outdoors?

i have recently acquired a fern which the roots grow on the surface of
the soil...like air roots....they are hairy like a tarantula spider
legs.
the fronds and leaves grow from these roots. they are small and very
delicate.
can anyone identify this fern for me please?

thanks.

Sounds like a rabbit's foot fern - Davillia or Humata. Those furry
extensions are rhizomes, not roots, but you can cut them off and root them
to start new plants. A great little fern and quite hardy, too - I have one
that has lived outdoors in zone 8 for about 3 years.
