Forsythia intermedia A. A. Reznicek


Shrubs of this familiar yellow-flowered Forsythia spread vegetatively from cultivation, and are barely established around old homesteads, and along roads and fencerows where garden refuse may have been dumped. First collected in 1965 in Van Buren Co. All the commonly cultivated Forsythias are introduced from eastern Asia.

This mounding shrub with arching branches is one of the commonest, and has the pith chambered between the nodes and solid at the nodes. Though treated as a species, this is suspected of being a hybrid of Forsythia suspensa and F. viridissima.
