Researchers stuck moss to the outside of the ISS for nine months and it survived.
The moss isn’t quite as hardy as the reigning king of extremophiles, the tardigrade, but it put up an impressive showing in an experiment where scientists exposed sporophytes (the reproductive structures that produce spores) to the harsh vacuum of space for 283 days. After crunching the numbers, they believe the moss could survive for around 5,600 days, or a little over 15 years in space and still survive and reproduce. According to the press release:
... Over 80% of the spores survived 9 months outside of the International Space Station (ISS) and made it back to Earth still capable of reproducing, demonstrating for the first time that an early land plant can survive long-term exposure to the elements of space.
