Last flower in the pond

Aw All alone..no I dont know :)

very nice K, is it a type of Pontederia cordata, although it may be a bit big for that..

Thank you W...that does ring a bell... :))

:-))

A very nice last flower!!! :)

At least it's not a lonely little petunia :)

Thanks all...it's been too hot for the pond this year. The waterlily only had three flowers, J (although that might also have had something to do with OH 'watering' it!), the iris keeled over at the end of June and, Scottish, the petunias gave up about the same time!

excellent photo - very nice indeed

Thank you, Paul! It's a deep water marginal and has been flowering since April...a very easy plant! :)))

Like Surreylad says, I think its Pickerel Weed.

Thank you, Dawnsaunt :)
