Hi I need to know if this plant is a weed. It is growing in my flower garden.

it depends on where you are, but it looks like one of my weeds in southern Indiana.

I think I'd wait until the first one blooms to see what they are - could be Sweet William (dianthus) or even lilies - tall stems with whorled leaves like that.

Doesn't look like you have very long to wait for the first flower - post another picture when that happens.

Looks like Conyza candensis..
