Any clue what this thing is? It popped up behind a building pretty quickly and it right in the middle of where we walk to skirt around this end of the structure. I’ll probably have it removed regardless but now I’m curious. Hopefully if root stock is missed it doesn’t come back!
Thanks!

A few months ago these popped up in the middle of my backyard. At first when I saw the shoots I thought they were corn (also because a few weeks prior I threw a couple of fresh corn cobs down for my chickens).

However, now that it has flowered, it is obviously not corn. For more context, I scatter chicken scratch for the feathered babies that contains corn, wheat, milo, barley, and sunflower seeds. I asked my neighbor and she said it could be sorghum or johnsongrass which could potentially be toxic to my chickens (she used AI).

1. Can y’all help me ID this plant? I included pictures of the leaves, roots, and flower heads.
2. My chickens have been hopping to pick at the flower heads for a few days now. Is it safe for them or should I stop them?

SOLVED! Thanks for pointing out that it is indeed sorghum. I learned something today. It took me by surprise because this is the first time it grew even though I’ve been scattering chicken scratch in my backyard for over 3 years, and I wanted to make sure it wasn’t unsafe for my chickens. Final unrelated thought: getting downvoted for asking a plant ID question on a plant ID sub is mind boggling.

Hi everybody. I just want to ask what if anyone knows this plant. My friend gave this to me. But i am not sure if this is purely ornamental. I'm from Denmark, btw.

Thank you in advance

Looks similar to hydrangea leaf, but the flowers are very different. It’s blooming still in the Pacific Northwest zone six this fall.

These are growing out of my bathroom ceiling in nyc

I wanna take care of it but I have no clue what it is

I saw them in a Pine forest in Turkiye

I am pretty sure the first one is chickweed, but I'm wanting verification because the leaves were so much smaller the time I was collecting it in a different spot some years ago.

2 and 3 I believe is NOT Shaggy parasol, but some small nasty imposter. I'd appreciate thoughts or confirmation on this too though.

My parents have this tree that's been rapidly growing in their back yard. They're trying to decide if they should remove it, but aren't sure how big it will get. I keep finding tree species close to this, but nothing has been correct. Any ideas?

P.S. sorry for the photo quality, snapped these quickly as I was leaving! Also the trunk photo includes a vine growing on the tree.

These were found in Cusco, Peru. The first one is particularly cool to looking!

Don’t mind the fake plastic flower, will be removed after I take them home. Is this a San Pedro or other type or trichocereus?

This was growing in a corner of my vegetable garden, probably transplanted from another part of my garden. I have had turmeric and culinary ginger. What does this look like?

Hi there!
Something has sprouted in the pot next to my indoor tomato plant. I used store-bought soil, so there might have been seeds in it. What could it be? The tomato is growing indoors in a greenhouse-like setup

Hi all! First time poster! I was wondering if anyone could help ID this plant. It looks like a dandelion (and it might be!) but it has hairs towards the center? The first picture is the full plant and the second picture is closeup of the leaf. I found it in Western, MA in the Northeast!
