According to Wiki it is a noxious weed in Alabama, Connecticut, Massachusetts, Maine, Vermont, and Washington. Never in a million years would I try to grow it in my garden.

'Grown in water gardens in UK since 1878, first recorded in the wild in 1960. Initial spread by improper disposal of garden and aquarium plants. Still found in some garden centres, often under one of its pseudonyms. Spreads by
vegetative fragmentation, no seeds are produced in the UK.
Causes flooding by blocking watercourses and drainage channels. Can rapidly dominate a water body displacing native species. Parrot’s feather is listed under Schedule 9 to the Wildlife and Countryside Act 1981 with respect to England, Wales and Scotland. As such, it is an offence to plant or otherwise allow this species to grow in the wild.' (DEFRA)

BTW, when I post pictures from travelling, I merely enjoy the plant without any intention to keep, plant or sell. Do you understand?

I mentioned the invasive tendencies of this plant because one responder appeared to admire it and might possibly try to obtain it.

Luckily, I knew this plant but when you post pictures from your travels it would be very helpful if you could say where and when you photographed the plant. That information helps greatly in identifying plants.

I cannot guess why any particular poster asks about a plant, unless they say so. Therefore, I often add information about its habits and preferences, if I have personal knowledge of them, rather than solely a bald statement of its name. I am just trying to help.

BTW it is invasive in France too.

There are waaayyyy too many invasive species being propogated (if that's the right term) due to people not understanding that they can be harmful to the environment, not to mention it's a nightmare trying to get rid of them once you've figured out you made a terrible mistake. Been there, done THAT....lol.
