It is fine to link like that, but on the first two, it would help to see pictures of the leaves too.

The last one, a yellow puffy flower, looks like Kerria japonica, a shrub.

I'm sure you can tell by the name that Kerria japonica is not native. I don't know if you meant to post this in the Native Plant forum or if you meant to post in the Name that Plant forum.

Here is a link that might be useful: Name that plant forum

Thanks I'll get some photos of the leaves for the other two and
post them in the other forum.
