Description

‘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.

Cold Hardiness

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.

Suggested Spacing: 8′ for privacy screen; 22′ or more for space between trees

Note: For our customers who live and garden north of USDA Plant Hardiness Zone 6b, where this Eucalyptus tree variety is not reliably winter hardy, you’ll be happy to know it can be grown in containers that can be brought indoors during winter and placed back outside when temperatures warm up in spring.

Growing Preferences

Big O Eucalyptus isn’t too picky about soil type. It will grow in well-drained soil but can also handle waterlogged soil It will grow in full sun but is also quite shade tolerant. It is also very heat resistant and we’ve seen no problems with insects or disease. Responds well to pruning so size is easy to control. With all these attributes, it’s no wonder this variety is a favorite!

My baby Big O Eucalyptus plant arrived at my home 3 days after I ordered it and it was in excellent condition. It has now been in the ground for 4 weeks and is thriving. The unusual square stems are supporting new growth and the tiny new leaves are most attractive. The weather has been very hot with thunder storms most afternoons and the plant is fully exposed, no shade. I am expecting this tree to become a classic specimen and hopefully it will be the subject of discussion because it will be the focal point in front of our restaurant. This plant is another example of the high-quality products offered by Wilson Bros.——————————————We are so glad you are pleased and we hope you enjoy it for years to come!

Once this plant was back in stock I ordered it immediately Shipment was very fast. The packaging was perfect! When I removed the plant from the pot it hardly had any roots which made me think that it had newly been potted for sale. It has put on at least a foot of growth but the main trunk is very thin and needs support. I hope that it will thicken its trunk as the summer progresses.———————————-Thanks so much for your review. Let us know if there’s ever anything we can help you with. If it’s growing, I’m sure the trunk will get more sturdy! – Beth | WBG
