I planted some seeds, orange cosmos and these sprouted up around that time and I thought it was them. But now wondering if its just a weed? They are about 10 inches tall, seem very healthy and no buds/blooms at all. How big do the cosmos have to be to bloom? I found some of these in an area that I didn't plant any of the seeds and that of course made me think I've been watering weeds. But I grew these in the past years ago and they looked familiar to me when they started growing. The last photo is the ones I found not where I planted them. I bought the seeds from Baker Creek.
okay guys thank you! I just started getting worried cause they are nearly a foot tall and no blooms yet.
@sallyg well i was supposed to add a different photo but it didn't show up I guess. Yes I did find some in an area not where I planted the seeds, but I can't tell if the plant is entirely the same or a close look alike. I should get out and pick one and put them side by side.

Cosmos are day hour dependent plants. I can't remember exactly how many daylight hours they have to get before it kicks them into bloom. That's why it's important to plant early, I think. I may have all this mixed up!

Side by side should do it. The other suspect in my mind is ragweed- Ambrosia artemisifolia? Ragweed leaves are placed oppoosite, I think Cosmos are too. Ragweed stems are hairy, Cosmos I suspect should be smooth https://www.illinoiswildflower...
I've grown the Sulphur Cosmos for years and that is what it looks like to me. I went out and took some pictures of the cosmos that I have for comparison. Looks like I also see some zinnias in your pictures... I need to get some of those too.
As an aside, I let cosmos grow all over my property. However, in 2017 I let it go wild in the daylily bed and will never do that again! The weeds underneath and were horrible to clean up. I did enjoy seeing all the butterflies and bees buzzing around it though.

So pretty, Vickie! But it sounds like Cosmos sulphureus made you so furious! LOL!

The best time to plant a tree is 20 years ago. The 2nd best time is now. (-Unknown)

okay I got some new photos, they are at least a foot tall and robust, no blooms, no buds that I can see.
They are definitely hairy along the stalk/stems. Shouldn't they have blooms by now? I'm growing weeds
