All Of My Callalilies Turned The Same Color Flower This Year, Why?

Question

I had callalilies with white (purple center), red, yellow & peach flowers last year in separate areas in my yard & this year all of the flowers are white with purple centers. I have had all but the yellow plant for several years & they never changed color before.

Answer 1

This is a strange one. I have two possible explanations.

The first- It is possible that the dominant colored flower is a stronger cultivar and has killed off the others in the area, replacing them with itself.

The second- It is very possible that color co-dominance for the flower color gene has allowed the more dominant color to be expressed.
