The bush—a Franciscan manzanita—was a specimen of a commercially cultivated species of shrub that can be purchased from nurseries for as little as $15.98 per plant. The particular plant in question, however, was discovered in the midst of the City of San Francisco, in the median strip of a highway approaching the Golden Gate Bridge, and was deemed to be the last example of the species in the “wild.” ... or the plant dropped out of someone's car, landed on the median, and took root.
