Zinnia : first flower grown in space

NASA astronaut, Scott Kelly, tweeted the photo of the first flower to bloom in outer space. The flower is the beautiful orange Zinnia, a flower native to southern United States.The flowers were grown inside the Veggie lab aboard International Space Station (ISS) which was installed in early May 2014. With the success of this experiment, Zinnia has become the first flowering plant grown outside Earth's atmosphere. The system, according to scientists, uses red, blue, and green LED lights to simulate sunlight, making the successful growth of the flower possible.
