Are these edible?

[trongbui]

I saw this plant in my back yard, and there are a lot. I'm wondering if it's safe for my Russian or not.

They look like Marigolds... in which case the answer is yes

I think its an aster. Its edible.

looks like it's this:

different from what I'd always called a Marigold, but searching "calendula" led to the common name "pot marigold"

it is an aster.

...what I'd always thought of as Marigolds however are in the Tagetes genus, also an Asteraceae:
