Morning glory seeds could potentially survive a trip between planets:

Natural sunscreens help morning glory seeds survive doses of ultraviolet (UV) radiation that would burn most humans to a crisp, according to a new study. The hardy seeds of the common flowering plant would probably even survive a voyage between planets, say the researchers. This might help researchers decide which species to send on future missions to Mars, a place that is bombarded with UV light because of its thin atmosphere. It also validates the concept of panspermia, the idea that life might have hopscotched through our solar system—or others—by hitching a ride on asteroids or comets.

"These results add to the fast-growing body of evidence showing that panspermia is not only possible, but absolutely inevitable," says Chandra Wickramasinghe, director of the Buckingham Centre for Astrobiology at the University of Buckingham in the United Kingdom, who was not involved in the study.

The research began a decade ago, when astronauts placed about 2000 seeds from tobacco plants and a flowering plant known as Arabidopsis thaliana on the outside of the International Space Station. For 558 days, the seeds were exposed to high levels of UV light, cosmic radiation, and extreme temperature fluctuations—conditions that are lethal to most forms of life. [...] They found that only morning glory seeds germinated [open, DOI: 10.1089/ast.2015.1457] [DX] after being exposed to light roughly 6 million times the dose typically used to sterilize drinking water, conditions that killed the much smaller tobacco and A. thaliana seeds.

Did somebody say interplanetary trip?

    Morning glory seeds could potentially survive a trip between planets

    Or, they could make you trip and imagine that they and you could survive a trip [wikipedia.org] between planets..

    The seeds of many species of morning glory contain ergoline alkaloids such as the psychedelic ergonovine and ergine (LSA). Seeds of Ipomoea tricolor and Turbina corymbosa (syn. R. corymbosa) are used as psychedelics. The seeds of morning glory can produce a similar effect to LSD when taken in large doses, often numbering into the hundreds.

    They must be eradicated lest a teenager get ahold of them, any benefits to terraforming Mars or science be damned. Besides, everybody knows that the world is flat, Mars is a wandering star, and science is, er, trying to remember... funding, fame, fraud???
