The growth of rose petals exploits a geometric trick previously unobserved in nature, physicists have found. Using theoretical analysis, computer simulations and experiments with rubbery plastic sheets, they established that as the petals curl outwards, mechanical feedback regulates their growth, leading to the formation of rolled edges and pointed corners at their tips.
The findings, described in Science on 1 May1, could one day have applications in engineering and architecture. “You might learn new principles and then implement them in manmade structures,” says Eran Sharon, an experimental physicist at the Hebrew University of Jerusalem.
