Flower #1: I see them very often walking around UBC. Has yellow flowers with 5 petals as well as white, feathery stuff with it. Flower #2: Tiny Tiny white flowers. Looks as if they have 4 petals that look like mini-hearts. Flower #3: 5 petals, that are pink in color. Leaves are scented. Flower #4: I am guessing they are a part of the Mint Family...not too sure. Has pale violet colored flowers with the ends of the petals resembling "forks."
