About the Tree
At one time, the world’s largest known pin oak was right here in Wisconsin.
It was growing on the campus of UW Stevens Point since 1894, but was removed in 2017 after being infected with the lethal oak wilt disease. During its 123 years of life, it had reached 92 feet in height with the trunk being over 4 feet wide.
Pin oak is somewhat unique in its tendency to exhibit a strong central trunk rather than the sprawling nature of other oaks. This form, paired with a relatively fast growth rate, leads them to attain impressive heights within their short lifespans compared to other oaks.
Our climbing tree in Sun Prairie is the only pin oak in our current line-up of climbing trees. This tree is surrounded by a handful of other impressive pin oaks and I encourage you to come out and meet them during one of our climbs.
The scientific name (Quercus palustris) comes from the Latin word for marsh, palus, indicative of the habitat where it is typically found in nature. The species tends to grow in lowland areas of the Midwest states, however, it can be grown across the continental U.S.
Having the ability to tolerate pollution and compacted soils, pin oak has been one of the most widely planted oaks in urban landscapes. Before you decide to plant this tree however, beware that the tree can face nutritional issues when growing in clay soils.
Starting my career in Missouri, I was fortunate to work with pin oaks that reached 100 feet in height. Since the species tends to hold on to its dead branches and twigs, I spent a lot of time in these magnificent trees.
