image of Smooth Owl's Clover from the Presidio Trust press release
1917 was the last time Smooth Owl’s Clover was last seen at the Presidio. That is, it was the last time it was seen until April 2009, when staff of the Presidio Trust spotted the bright yellow flower not seen in the Presidio in 92 years emerging from the soil.
