Rose
Three methods of divination utilizing roses are available for use. The first, known as phyllorhodomancy, consists of placing a fresh rose petal in the palm of your left hand, then smartly snapping your right hand against the petal. If this creates a loud sound, the signs are favorable or the answer is yes. If there is a little sound, the reverse has been divined. (This practice is of ancient Greek origin.)
Alternately, obtain three fresh roses. Place these in three vases that aren't filled with water. Name the left rose "yes," the middle rose "no answer" and the right rose "no." The flower that remains fresh after the other two have withered reveals the outcome. Check them several times a day to observe their progress.
Finally, a rose love oracle: fill a basin with rose water (or, failing this rather expensive commodity, plain water). Pluck three leaves from a rose plant. Name each for a specific person that you wish to become involved with (but are having difficulty making up your mind). Place these on the surface of the rose water. The leaf that floats for the longest time on the water's surface indicates the favored choice.
