Formula to insert parentheses

(I have around 600 species names)
I need to be able to insert parentheses around the “common names” of different species. Some species will have different number of names.
Right now, my list looks like this:
Asclepias amplexicaulis Sand Milkweed
Agastache scrophulariaefolia Purple Giant Hyssop
Aster ciliolatus Lindley's Heart-leaved Aster
Aster novae-angliae New England Aster

I need it to look like this:
Asclepias amplexicaulis (Sand Milkweed)
Agastache scrophulariaefolia (Purple Giant Hyssop)
Aster ciliolatus (Lindley's Heart-leaved Aster)
Aster novae-angliae (New England Aster)

THANKS!!!

Assuming the first word in parentheses will always be the 1st capitalized word in the string (excluding the very first word):

=LEFT(A1,MIN(IFERROR(FIND(CHAR(32)&CHAR(ROW($65:$90)),A1),999)))&"("&REPLACE(A1,1,MIN(IFERROR(FIND(CHAR(32)&CHAR(ROW($65:$90)),A1),999)),)&")"

You must confirm it with Ctrl+Shift+Enter since it's an array formula.
