Need Verification on Plant Name

[Madman]

We've had this plant in our pond for at least ten years, but i think it is more like 12-15 years. I believe it's called a Japanese arrow, but it's been so long since we bought it, my memory is fading.

When first purchased, it was about a foot high with three or four stems. The garden center salmon or salesman told us it would not survive winters and that we should take it indoors each fall. Well that never happened and as you can see it loves our pond and has grown to five feet in height and width. It has also spread it's off spring around the pond in several places.

Ha, ha, good catch. The spell check is quicker than the eye.

Thank you. I knew it had some kind of arrow name. The site you posted indicates a two to three foot growing height. Mine has exceeded that by two.

They refer to cutting it back each year?

Perhaps you have two-years growth??

Each year the leaves and stems turn brown in the Fall. Then I cut them back as low to the water's surface as I can. In the Spring it's all new growth. So the picture I posted is this year's growth. The plant keeps growing in width under the water's surface, just like any similar plants do on land, like Daffodils or Lilies of the Valley. There are seeds that fall from the plant most of the Summer. A few seeds have found places to root so I have a half dozen or so smaller versions of the Arrow plant. Next Spring I have to cut some of the root system off of the large one as it will reach the other side of the pond and block some of the water flow to the filter.
