The foliage of the Zelkovas are starting to turn orange and red for fall. Green Vase, Zelkovaserrata 'Green Vase', is a great choice for tough urban areas including street trees and parking lot islands. The upright vase shape form also works well on residential properties. The dappled shade of the foliage allows grass to grow under the canopy. Green Vase is a fast growing tree that matures 60x40'.
