Pick of the Month
Here is an explanation from John for those who would like to know more about how the colouring in the flowers comes about:
“The more commonly seen orange clivia has red anthocyanin in the outermost cell layers of the petals and sepals.
The middle layers of cells contain yellow carotenoid pigment.
The overlay of red on yellow produces the orange colour that we see.
In the case of peaches, like mine, there is a naturally occurring mutation in the anthocyanin pathway which results in only a small amount
of the red pigment being deposited in the petals and sepals.
The overlay of this dilute red over the yellow in the middle cells results in the peach colour of the flowers.
The physical difference between a yellow flower and a peach or orange flower is that with a yellow a mutation results in a total blockage of the anthocyanin pathway
so that no red anthocyanin pigment at all is deposited in the outer-most cell layers of the petals and sepals.
All that is visible in the flowers of a yellow clivia is the yellow carotenoid pigment in the middle layers of cells in the petals and sepals,
underlying a clear layer of outermost cell layers.”
