I suggest 3 options for your colliding flowers:
  - change the random seed.
  - slightly increase the spacing of the flowers. Just miltiply the 
horizontal locations by 1.03-1.05 before tracing.
  - add an exclusion cylinder centered around each flower, binded in an 
union. The cylinders radius will dictate the minimum distance between 
two flowers. You perform an insideness test on that union before you 
place a new flower.
