syngoniums:

A lyside sulphur (Kricogonia lyside) on goldeneye (Viguiera dentata), a pipevine swallowtail (Battus philenor) on scarlet muskflower (Nyctaginia capitata), and queens (Danaus gilippus) on Gregg’s mistflower (Conoclinium greggii). I think only the large butterflies can take advantage of the scarlet muskflower, but the other two are huge favorites with just about every insect pollinator.
