Color Variation at Its Limits 



Composite flowers usually arrange the colors of their ray 



flowers symmetrically. But here is a dahlia that has departed 



strikingly from the traditions of its tribe, presenting some petals that 



are striped and others that are of uniform color. It would b 



interesting to observe the range of color variation that 



would be shown by the plants that might be grown 



from the seeds of this single flower.
