The flowers she's holding are daisies (daisy). The ones on her kimono are peonies (peony_(flower) and floral_print). The ones above and to the left and right that look a little like daisies are cosmos_(flower). The ones in lower right corner that aren't daisies are lilies (lily_(flower). There are also roses and cherry blossoms.
I'm not sure about the rest, although the ones to the left of her knee may be hydrangea.
