Rainbow Eucalyptus (Eucalyptus deglupta)
Source tree from Shamus O'Learys, Apr 2016
This was already a beast when I bought it. 3 gallon tree but was 12 ft tall. I planted it on the west side of my property to serve as an afternoon shade canoppy tree. The last couple of years the trunk has been getting larger and is now starting to show some of its famous striation. Not very colorful yet, but beautiful all the same.
