Wonderful except the plants doesn't match any of the Amaranthus shown in the
link.

It could just as easily be a Celosia.

The difference between the two genera is slight and they have been reported
to hybridize.

Amaranthus [stigma 2-3, distinct to the base]

Celosia [stigmas united into a style]

My father has some volunteer plants in his butterfly garden (mostly
zinnias).

We are unsure as to what this is

Amaranthus. See:
