Karen wrote we've had some very cool nights (45) and not real sunny warm
days,
that may be what's stopping it from growing.
My parrot's feather did not start growing until it warmed up.
I'd give the plant the full growing season to see what it does.
I've grown parrot's feather in the frog bog,
still water and full sun. It took over.
It is such a prolific grower that it is now banned in my state.
I ripped all mine out, not getting it all of course, and it is starting its
second season in the compost pile!
Be careful what you wish for.....
