Love my parrot feather; my pond is small enough that I can pull it out by the handfuls mid summer when it is spreading too much. Before my pond was deep enough to stick a parrot feather root in the flower pot with the water lily 3' below the surface, I used to winter it over indoors in a large flower pot filled with water, a couple of baby goldfish, and just a handful of mud in the bottom of the pot. By spring, it would be spindly, but I'd just throw it back in the pond and it spread again every year!
A problem anywhere other than controlled in a home pond. DO NOT let it get out into waterways. This is like the water hyacith. Lovely only when it's controlled. Very easy to grow. In my pond, it has overwintered with NO protection for 4 years

parrots feather grows well in alkaline soil-tho i've never seen the blooms. each segment will regrow roots n the hotter n more humid it is, the faster it takes over. it is listed in library books for water gardens as a plant that steals oxygen from the water, rather than generating new oxygen. and it is a nuisance when it gets loose.

I've had it winter over here in zone 6A as long as the roots were tucked in mud. I used to just let it float but noticed it does much better if planted. I planted some in a new lotus pool last summer and it went bonkers, sprawling way out beyond the edges of the pool. Any part that was out of the water is now mush.

I'm not so sure of the Zone classification.
I have it growing in a barrel outdoors.
It is growing quite well after being totally frozen in the ice.
It maybe needs a Zone 5 or 6 classification at least.

I just love this plant! It floats around under the surface, feathery "heads" sticking up above the water. Have you ever tried pulling one of the "heads" below water? They don't get wet, but just kind of close up with silvery air bubbles trapped between the fronds. Neat!
These also normally close up at night. Interesting.
