Unveiling the Picea orientalis 'Mt. Vernon'
The Picea orientalis 'Mt. Vernon' is a selection of the Oriental Spruce (Picea orientalis), a species native to the Caucasus region. This tree was introduced to the horticultural world in 1962 by the esteemed plant breeder and nurseryman, John G. Gordon, who named it after his hometown, Mount Vernon, Washington.
Distinctive Features
What sets the 'Mt. Vernon' apart from its parent species is its striking growth habit and needle color. Here are some of its distinctive features:

- Blue-Green Needles: The 'Mt. Vernon' boasts stunning blue-green needles that contrast beautifully with the tree's brown, papery bark. This unique needle color adds a touch of vibrancy to any landscape.
