Cross-pollination may result in pink offspring from both parents' genes, but the existing plants remain the same. By the same token, if an inter-racial couple get together, their races remain constant while their children inherit traits of both parents. Consider the results of human genetics and it makes sense. Many white flowers, as they age, may take on non-white tones which some people attribute to what was mentioned, but it's just a result of natural aging in the flower. White trilliums turn slightly pink as they age, for example.
Is it true? if I plant white cone flowers near pink cone flowers they will turn pink?
Sometimes that can happen, due to cross fertiliation.
Reply:Not likely. Usually for cross pollination to occur you have to have red and white flowers next to each other. That's usually how pink flowers are created. Another way that the white flowers might change color could be related to what the soil has in it. For example if there is iron in the ground then the flowers could turn reddish brown. If the soil is more acidic or base that can also have an effect on what color the flowers become.
