Choose the daisy colors and large blossoms; select three de-thorned, long-stemmed roses and pick a versatile, elegant container. A simple squared glass vase adapts to any décor and will display the tall flowers to advantage. Place some clear glass pebbles in the bottom of the vase to help anchor the flowers. Fill the vase halfway with cool, not cold, water and add a small amount of florist's preserver to keep the daisies looking fresh longer.
Slip curled wire supports up the stems of the daisies to the back of the flower head and gently poke the tip through the flower. Holding the end in place at the flower, slide the wire coil down the stem, uncurling it as you go. The flower will now stand stiffly in the arrangement. Trim the stems on an angle with a florist's knife, varying the heights slightly so more flowers are visible when they are in the vase.
Arrange flowers in the vase so the faces show. Push them into the pebbles at the base of the vase to help hold the flowers in place. Fill in with a few fronds of leather leaf fern mixed with strands of bear grass.
Trim the stems of three cream or yellow roses from tall to short. Tuck the shortest in the front of the daisies, the mid-height in the middle but off-center, and the tallest in the back, in front of the greenery. Adjust the greenery so a few strands of the bear grass are mixed in among the flowers.
