First zinnia in space

A bright orange zinnia has blossomed aboard the International Space Station, marking a first in space."

"First flower even grown in space makes its debut," US astronaut Scott Kelly wrote on Twitter, with a photo of the flower.

Zinnias grow easily on Earth and blossom in abundance in summer. But on the ISS, where they were taken to carry out experiments, they have had trouble adapting to microgravity.
