A new study has revealed that some flowers can heal with remarkable speed after a major accident, such as being walked upon by humans. Scientists observed that varieties including orchid and sweet pea could recover themselves in 10-48 hours after damage. These specific plants can turn, twist and readjust their stems to assure that they reproduce. Scientists studied 23 native and cultivated flower species in South and North America, Australia, UK, Europe. Research indicates that most of the bilaterally symmetrical flowers such as snapdragon, orchid, and sweet pea have the potential to accurately restore their stigma after injury.
