There aren't a lot of ferns, cycads, etc. eaten today. You would be
seriously lacking protein in the absence of grains and legumes, and
quite a few ferns and fern allies are either toxic or contain enough
silica to be inedible. You hear about people eating fiddleheads, but
only from one or two species, and even then only at certain times. If
the characters in your book have time to do any research, have them
learn which few species might be edible.

Seeds of modern plants *would* grow, but you would run into problems
with those whose pollinating insects have yet to evolve. E.g., beans,
which are largely self-pollinating, might be all right, but things
like squash which have relationships with solitary bees are not going
to set fruit. Do a little research into when the different groups of
insects arose.

Any of them could be eaten?
Do you think if someone could take with himself modern vegetables seeds,
would they grow in that clima and atmosphere composition?

"Eight Miles High"--

Very nice piece of art.
