Not at my computer right now and haven't looked at Mark's version. The flowers if I remember correctly are symbols with their own timeline. So you can duplicate the symbols and give them an ID that increases in number so the next in the sequence. (look to the other symbols for the naming)
Also, you would need to increase the counter condition as Mark states to account for the increase in flowers. If you create a new timeline or a rotation you could call that timeline similar to the way the other timeline is called.
Bear in mind that the code you posted above has been commented out. (the // before it)
