The Highrise Live Oak is an evergreen and grows to a mature size of 30 – 60 feet tall, with a spread of up to 40 feet wide. This canopy tree has an upright, compact growth habit with a dense foliage canopy. Preferring to be grown in full sunlight, the Highrise Oak grows at a fast rate and can even live up to 150 years old or more. Able to tolerate many types of environments, it can thrive in high traffic inner cities, as well as in the yard of a humble home.
The Oak Highrise is one of the industry’s first patented clonal live oaks. Genetically identical in all characteristics for long-term uniformity and consistency, the Oak Highrise is quickly becoming the tree of choice where restricted growing areas are of concern. Due to it’s weather resistance and more moderate footprint, it is ideal for areas where space is limited. Tree plantings along boulevards, parking lots and planters will be forever enhanced by planting this oak variety.
The Highrise Oak tree can be messy, and may require light maintenance to upkeep. It is best to prune them at the end of winter after extreme cold temperatures pass. Many varieties of birds and mammals, including squirrels, are attracted to it’s flowers and fruit.
