Is this a weed or aquatic plant?

    We found a plant in our backyard that we aren't sure of. It may be just a weed but there is a possibility that it could be an aquatic plant that can be grown emerged.

    I have aquariums and sometimes when I do water changes and pruning, the odd cutting will end up outside when I dump out the water. Most of the plants in my tanks are plants that are naturally aquatic but they can be grown emerged.

    So what do you all think? Does this look familiar to you? The plant is about six inches in length and the stems and leaves of it is very soft. It doesn't seem to need full sunlight as it is growing along the side of the house that doesn't get any direct sunlight.

    Thanks.

    Leaves perhaps too finely and frequently divided but flattish main leaf stalks are like those of pineapple weed. Does it smell?

    I just went outside to sniff the plant and there is no smell. I also checked out the plant that Audrey mentioned and the stems of that plant look a lot more stiff and the leaves are more spaced out then what we have.

    I'm going to check out some of the aquatic plants that I have online to see if I can find any pictures of them when grown emerged to see if they match up with the plant outside.

    There are some yellow(?) flowers in making seen on the bottom of the second photo. Check on them when they open and count the petals. If there are four petals, this could be something from Brassicaceae family (like Descurainia). If there are five petals, this might be one of the Apiaceae family member.

    Could be Anethum graveolens, commonly known as Dill.

    There are no flowers on it. What you are seeing is a small bit of a dead leaf. I didn't remove it from the plant when I took the picture. :/

    The stems don't appear to be very strong. Now that it's getting taller, the stems are bent over instead of being straight. I found this site when I looked up Dill and it could be it. If there were flowers on it I'd be able to compare it a little more.

    Thanks everyone! :)

    Crush the foliage and report back on the scent.

    Already mentioned it's odorless, so not Dill at least. Of course I'm assuming it was crushed, but
    never assume, right?

    The branching style is not quite dill-ish. The dill petiole is round in section, here is looks flat.

    Foeniculum vulgare and Cuminum cyminum are other possibilities.

    Sorry for taking so long to get back to this thread. Allergies suck.

    Yes, I did crush the stem that I broke off to see if it had a scent and all it smells like is fresh cut grass and it was not strong.

    Here are three more pictures of the plant stems and leaves. The main stems are round but the branches from them look flat. From the pictures that I looked up, it does look a little bit like the Cuminum cyminum that Audrey mentioned but it would probably be easier to tell if the plant had flowers on it.
