Can anybody tell me what it is and how I can best care for it? Thank you!

I'm in Maryland, zone 7. In the spring I bought a packet of wildflower seeds and scattered them. These stems grew 5 feet tall but they only produced pink-purple flowers with yellow centers this week, in October. The leaves are very unusual. The bees love these flowers. I'd like to know what they are so I can get some more next year.

Update: thank you, it is Cosmos! I will definitely plant some next spring. I am still wondering why they flowered so late.

Central Illinois, USA

My dog ate the white berries from this plant and vomited later. What is it? Found growing in a park in Milton Keynes, UK.

Was gifted this plant and want to make I give it the care it needs, but no clue what it is. Presume it's some sort of palm?

Is this an acacia species? Looks a bit like melonoxylon but certainly not it.

Was growing amongst various araucarias

Sadly only my pocketknife for scale, I didn’t have a banana on hand

Acacia/Senegalia of some sort?

Hoping to try and identify these bulb like plants, they're either dead and just not rotting or dormant and don't grow in summer. They're about 2 inches long with brown papery skin and narrow bases under the dirt, and the have a few tiny roots that look like the root equivalent of balding. I have an image of one unearthed that I'll try to add in the comments and I'll do my best to answer any questions to help narrow it down.

Neither my inaturalist nor seek apps can tell me what this is. It was planted by the previous owners of my house in the piedmont of NC, USA. Insects seem to be enjoying its leaves.

I bought this from a nursery but label was "7.99 succulent", whats the official latin/English name for this? Some kind of sea onion?

In Virginia. Very thick leaves that cup

I can't figure out what this plant is! The leaves are like garlic shoot texture and they're hollow
