Here is a picture. It grows on the banks near the edge and in up to a foot or so of water.

It looks to be in the water-plantain family, maybe Alisma.

Agree - looks like my arrowhead - it's a beneficial plant for sure.

Is arrowhead easy to control? I need to find some plants to supplement our American pondweed, which is pretty easy to control. Thanks. BM61.

In my experience arrowhead is a beneficial emergent plant very desirable, I've never needed to manage it in any way it's never been out of control.

Tj I have access to tons of arrowhead.... would it be good to transplant it to my pond and if so where would you place the starts? Also have read that the tubers are edible

There are different species of arrowhead. I have a couple, including duck potato. I too like the plants, but I maintain a "natural edge". No cattails though!

I have the arrowhead plants in my pond and absolutely love them. They occurred on their own and thankfully so. My pond is only a year and a half old since renovation so I can not speak too much on how they age with the pond, but at this point they are lovely. They don't grow deep in the water so removing them is not too bad even though I have not had to remove any.

I was thrown by your photo by not noticing the "V" at the base of the two largest leaves. I'm still not convinced they are arrowhead, but maybe your plants do not have a very pronounced notch at the base of the leaves. Here are some pics of mine...





Mine are not flowering just yet, but they should in the next month or so, IIRC.

Hi Pat sorry for the late reply. Yes, I'd encourage it to grow through transplant. I do that often in my ponds with sedges, rushes, arrowhead and other plants I view as beneficial. I'm a huge fan of emergent vegetation as it helps reduce nutrient levels but doesn't impact angling.
