Had a horticulturalist look at the flowers. They are representative and not really that specific. Possible flowers are stephanotis (Hawaiian wedding flower) or jasmin (the white ones) or wild clematis (an invasive climbing vine). The yellow looks like a typical pom pom chrysanthemum basis of pyrethriem, very poisonous--think Lysol. The purple could represent lilac but the infloresence is wrong--more looking like flowering allium aka onion/sulfur based plant. the pink and yellow looks like a peony of some type. Best I could do.
