| But interesting -- iris-type leaves but it has thick fibrous roots. Any ideas? |

| If the flesh of the roots has a pinkish tinge it's Iris pseudacorus. If not, post a pic of the root. |

| I will pull some up -- I recall them being rather bright white. The leaves are somewhat fleshy if that helps. |

| Looks like cattail. FataMorgana |

| Was thinking cattail as well. Must be a rather wet spot if it is. |

| Iris pseudacorus leaves have a raised midrib along the middle of the leaf. The sap of the root is black. The leaves are covered with a fine waxy powder that gives them a glaucus cast. If it's planted in too much shade, it won't flower, or will flower very late, so waiting for a flower to ID in that case might take a while. If it is yellow water iris, it's on the invasive species list on many states. But don't immediately dig it up and compost it, because I. pseudacorus does have cultivars, and it's only the species that is considered invasive. Cattail leaves have parallel veins, they are stiff, and rounded on the back. They also twist - some sources say along the entire length, some sources say towards the top. Cattails only grow in standing (still) water up to but not more than 6 feet deep. |

| "Cattails only grow in standing (still) water up to but not more than 6 feet deep." Not true. They can and do grow in saturated soil though not nearly as
vigorously as in water. |

| Did that *really* need to be stated? Yes, cattails also grow in bogs and marshes and "water-saturated soil" - anywhere the water isn't deeper than 6 feet and is not *moving*, such as a brook or stream, although, since we are being *precise* here, they will grow in the middle of a stream if there is a pool of still water, such as downstream of a boulder or on the inside of a bend in the stream. And they don't stop growing at the margin of still water because water doesn't stop at the margin. It penetrates into the soil around the body of water (unless, being *precise* again, the body of water is in stone or otherwise impenetrable material), and since water levels fluctuate, cattails have to be adaptable to those fluctuations. And, I suppose that water penetrates deeper than a body of water, too, which means that the roots of cattails probably also go much deeper than 6 feet, which means that they can possibly grow in saturated soil deeper than 6 feet. Jeez! That'll teach me! |

| Seemed appropriate to point out since the plant in the image does not appear to be growing in standing water and if cattails only grew in standing water that would suggest the plant in the image is not a cattail. |
