patented or trademarked orchids.

[pinkham]

So here's another angle..
What happens if someone patented a certain orchid hybrid...lets say for this thread that the future seed pod parent is "alice" and the father is "fred"....
What if alice and fred were very common orchids and the seeds they produces were germinated and patented after growing...
What if I had those two same orchids( because they are common) and went through the whole process with my own seed pod. is that infringement?
