Being at the right place at the right time: In October 2009 a botanist driving along a busy San Francisco freeway spotted something growing in a traffic island surrounded by ramps near the Golden Gate Bridge. It turns out it was the long-lost Franciscan manzanita, last seen more than 60 years earlier. Excellent story on how rare plants are being saved and hopefully be brought back from scarcity. #science #nature #plants https://therevelator.org/manzanitas/
