Alpine Yellow Gum Eucalyptus Tree
A most unusual cold hardy Eucalyptus species, Alpine Yellow Gum Eucalyptus is unique for its deep green foliage, as opposed to the typical silvers and blues of Eucalyptus. Trees are sturdy and grow very upright to about 30′ tall in 10 or so years. The bark is the real attraction here, featuring handsome reddish brown streaks in youth and maturing to silver and bright YELLOW when mature! One of the most unique bark colors you might ever see for a tree that’s hardy to Zone 7b. Alpine Yellow Gum has performed very well for us here in Portland and will resprout from the base in climates where severe frost knocks it back. It can also be coppiced to maintain its juvenile foliage and a smaller shrub, though you won’t be able to gaze upon its gorgeous yellow bark if coppiced.
