It is common in some flowers to see the pink hews flush on white flowers when moved into some soils. I would imagine mineral overburden or deficiencies may effect colouration, but only in some cases. The classic example of a plants possible colour uptake abilities, is the old die test on a cut flower in a cup of die, many flowers will quickly draw colour into their petals. I wonder if you had a range of soil dilutions & a bunch of white carnations, would we get a result ? Would be a fun experiment. -- Steven : ) Esk Queensland Australia Summer Zone 5 Winter Zone 10
