You claimed the oldest known plants are under 10,000 years old and now you claim you never stated otherwise. You are a liar.
Since you clearly have misunderstood me several times (probably intentionally, but we'll leave that be) let me summarize my position in words you can hopefully understand:
1. No individual plant alive today was alive during the Pliocene.
2. No individual plant alive today has identical genetics to those alive during the Pliocene.
3. There were plants we call 'ferns' during the Pliocene. 'Ferns' is a large category of plants on a simlar level to 'grasses' or 'mammals' or 'reptiles. That there were 'ferns' during the Pliocene and 'ferns' existing today does not imply in any way that todays ferns are identical to those during the Pliocene. In fact, it is well known that most ferns found today are quite different from those during the Pliocene, Just as most mammals and most reptiles are quite different.
4. The fact that Plants during the Pliocene managed to survive high levels of CO2 tells us nothing whatsoever about how well specific species will do today.
