Hi Steve - I used to grow Rodgersia in a previous garden - this one's too free-draining.
I remember new plants taking a little while to get going - they also really like their roots in damp to boggy conditions - although yours are by a stream is the bank dry? We've had a very dry spring.
The new leaves are the ones that are lovely copper colour then they turn greener as the season develops.
