I would have just guessed it was an aging flower (the one with "bleached" tips) but I take it all flowers opened at the same time?

Rick, you'll have to wait till next fall to see if these new traits are permanent or just caused by some random temperature fluctuation or something.

I would think that the two flowers are slightly different ages.  But I have had many open flowers so far (I counted 83), some already senesced, and none have exhibited any deviations from homogenously colored petals at any time.  I have always assumed that the whole petal develops at a pretty equal rate, but perhaps that is not the case.

Update:
Soon after that pic was taken yesterday, I watered the garden.  Now, 25 hours later, both anomalies have almost disappeared!
         

And all the colchicums seem happier.  If there was a water deficit for that one bulb, and petal development differs from one end of a petal to the other, I suppose that could explain it.  As Trond says, next year's bloom should tell.

A pleasing light color, Luc. 8)

Do you know what makes it a new species?

This one is related to C. lingulatum that grows on higher habitats (500-2300 m).
Botanically speaking there are differences in leaf shape and in the number of flowers on a bulb (2-5 for C. lingulatum - 1-2 for C. sfikasianum).

A first flower for this season on one of the plants in the C. cupanii complex. These suffered a lot during last winter with a lot of dead one's as a result.
Colchicum cupanii var. pulverulentum from Zaghouan Tunesia.

The petals almost look pleated. 

Are my eyes tricking me?
