What is variegation?
Question; Why does leaves produce variegation? I have talked to a hosta nursery owner in Ohio and he explained it this way. There are mainly 3 ways plants produce variegation in there leaves. 1 Chemical, 2 Radiation, 3 Old age.
#1 Chemical; a lot of toxins weaken the cell structure and most effects are only temporary. #2 Radiation; again breaks down the cell structure but also changes it's DNA component. Effects are more long lasting. #3. Just like us, as we age we tend to go gray. same as plants. A overgrown and old clumps is where you find off shoots of variegation. Known as sports. But what is known is that variegation while looks attractive, is actually a weaker poorer plant. mostly never achieving the potential of the mother plant it came from. Any thought about this? I am still learning. Any help/comments?
