Special Attributes

'Big O' is one of the most popular of the Southern Eucs series of cold hardy eucalyptus trees. Development of the Southern Eucs began in 1997 when an English botanist working in Atlanta, Georgia realized that there was little winter temperature difference between the native locations of many eucalyptus species he had collected in his explorations and colder regions of the United States. The team at Southern Eucs carries on this legacy by expanded explorations to find and test-trial all the varieties of eucalyptus trees that will thrive in colder regions of the United States. 

Eucalyptus neglecta 'Big O' is quickly becoming one of the most popular eucalyptus in the United States. It was named "Big O" for its unique, large, rounded leaves. Juvenile foliage is vivid blue with red highlights, fragrant, and a stand out in any floral or dried flower arrangement. The juvenile leaves are large and round and on square stems, and usually persist for 7-15 years before any adult leaves are seen, which are elongated. In a cool, moist climate the foliage assumes a fabulous purplish hue. The bark is rough, fibrous and grey on the trunk, turning smooth grey and green above. Big O is highly rated for its cold hardiness.  All grown up Big O could reach 20' in height with an equal spread.

Because of its seed provenance, Big O can handle temperatures down to -10 F. In Atlanta, Georgia, 10 month old trees had minimal leaf damage and looked great after a brutal winter (2013/14) where temps reached 6 degrees. In Western, NC, 10 month old trees - that froze to the ground at -10 degrees - are growing vigorously from their base.

Landscape Uses

Growing to 20 feet tall with an equal spread, 'Big O' is a fast growing but smaller Eucalyptus tree that will beg to be planted as a focal point in your garden. It is one of the best Eucalyptus in the shade. Can also be useful as an evergreen hedge or screen.

Pleased with my tree
Small tree in a 1 gallon pot but I know they grow fast. Fast delivery and the tree was in very good condition. Thanks for the tip on not to disturb the roots when planting...I didn't know that about Eucalytpus. Overall very satisfied. I never give 5 stars but if I did I would've given it here.
