Sierra Madre Wistaria

Giant flowering vine in California. Largest single flowering plant

About

Sierra Madre Wisteria or The Wistaria Vine is a flowering Wisteria vine shown at the annual Wistaria Festival in Sierra Madre, California. The Wistaria Vine in 1990 was declared by the Guinness Book of World Records to be the largest blossoming plant in the world. The Wistaria vine is named after physician Caspar Wistar (1761–1818) by botanist Thomas Nuttall (1786–1859). The general name for the plant is spelled Wisteria. This single wisteria vine covers over an acre. The Wistaria Vine has over 1.5 million blossoms and weighs over 250 tons. The plant is on private land and open to the public once a year during the Wistaria Festival.
