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. Get all the details below!
